How to determine the location of a car

When we drive, we need to know where our car is on the road, how far the body is from the sideline, and how far it is from the center line. Novices are often not sure when judging the position of the car. Through several pictures, I try to explain how to judge the position of the car, for reference only. There may be some errors in different judgments when driving a vehicle, so you have to sum up your own experience.

1. To judge the position of the left wheel, we need to know where the left wheel will pass through to avoid the tire from pressing on the solid line, or to avoid potholes and stones on the road. When our line of sight coincides with an object on the ground through the protruding node of the left wiper, our left wheel will press over the object while traveling. For example, in the picture below, if the wiper node coincides with the center line of the ground, then the tire will pass over the center line.

The left wheel presses the center line

2. 60 meters away from the center line When we drive normally, it is safer to be 60 centimeters away from the center line. When our line of sight coincides with the center line through the intersection angle of the cotton panel and the A-pillar, the car body is exactly 60 centimeters away from the center line. The car body is 60 cm away from the center line

3. Determine the position of the right wheel. When our line of sight passes through the right wiper and intersects with the target, the tire will press the right wheel from the target and has already pressed the line

4. Driving with the right side 60 cm away from the roadside. When the right sprinkler overlaps the target on the roadside, the vehicle body is still 60cm away from the roadside. There are still 60 centimeters from the curb

5. Pull over to the right. When the right wiper node coincides with the curb, pull it slightly to the left to achieve the effect of pulling over 10 centimeters from the curb. How to judge the distance between the front end of a car and the person and the distance to the car in front of you 10 centimeters from the roadside. Determine the distance between the front end of the car and the person: Taking a car as an example, assume that there is a person in front of you who is about 1.7 to 1.8 meters tall, with a foot height of about 10 cm, a knee height of about 45 cm, and a hip height of about 70 cm.

1. When you see the front end of the car move from the ground to the feet or heels of the human body and stay there, the distance between the front end of the car and the human body is 3 meters.

2. When you see the front end of the car raised to the height of the human body's knees, the distance between the front end of the car and the human body is 1 meter.

3. When you see the front end of the car rising to the lower end of the human body's buttocks, the distance between the front end of the car and the human body is 0.3 meters.

Judge the distance to the vehicle in front:

1. From the lower edge of the windshield to the upper edge of the bumper of the vehicle in front, it is about one meter;

2. It is about two meters from the lower edge of the windshield to the lower edge of the bumper of the car in front (human feet and knees);

3. From the lower edge of the windshield, you can see the lower edge of the rear tire of the car in front (or look at to the ground) about three meters;

4. The horizontal line relative to the ground seen from the lower edge of the left rearview mirror is the position of the front of your car.

Use the right rearview mirror to determine the distance to the vehicle behind:

1. When the shadow of the rear vehicle occupies the entire rearview mirror, the distance between the vehicle and the vehicle is about 3 meters

2. When the car shadow occupies two-thirds of the rearview mirror, the distance between the cars is about 5 meters;

3. When the rear car shadow occupies one-half of the rearview mirror, the distance between the cars is about 9 meters;

4. When the rear car shadow occupies one-third of the rearview mirror, the distance between the car and the car is about 12 meters;

5. The left rearview mirror can see the middle of the rear wheel cover (the rear door handle, The horizontal line of the car body or the bottom line of the rearview mirror (reflected from the bottom line of the rearview mirror) is the rear position of the car relative to the ground.

6. Use the interior rearview mirror to look through the lower edge of the rear windshield to determine the distance to the car behind you: If you see the upper edge of the headlights of the car behind you, the distance between the rear trunk and the car behind you is about three and a half meters. ; If you see the junction between the engine compartment cover and the front windshield of the rear car, the rear trunk is one meter away from the car behind you; if you see one third of the horizontal side of the front windshield of the rear car, it is basically close to it. Determine the vehicle position (wheel position, front and rear position):

1. Determine the position of the roadside in the windshield (the left wheel is 10-15cm to the right of the left pillar of the windshield; the right wheel is in the windshield 5-10cm to the left of the center line of the glass); the distance from the roadside can be seen in the rearview mirror.

2. Determine the position of the right wheel (middle of the front of the car or the right wiper): one-third of the way to the right of the front cover of the car relative to the ground. The following are the emergency tips for driving on the road. I hope it may be beneficial for you to read them carefully.

1. Driving Skills The foundation of driving safety is technology and experience

1. When getting in the car, look at the car first. Go around the car before getting in, and check the car’s appearance, tires, Are there any oil or water leaks under the car? You have to open the cover and check the engine oil, cooling water, and brake fluid once a week.

2. During the ignition step, tighten the handbrake (to prevent slipping), depress the clutch to the bottom, put it in neutral, and do not step on the accelerator (accelerator pedal). Turn the key to the II position and stop for 6 seconds to allow the car's electronic system to start. Electrical self-test, start the lubrication system, and then continue to turn the key to ignition position III. After successful ignition, shift into first gear, release the handbrake, slowly lift the clutch, refuel, and set off.

3. Warm up the car first before driving. There is almost no need to heat up the EFI car. Warming up the car here refers to starting the lubrication system. After parking for more than 3 hours, after the engine ignites, idle for more than 10 seconds, and the tachometer drops to about 1,000 before starting the car. In severe cold weather in the north, the idling warm-up time should be appropriately extended.

4. The first gear starting car transmission design focuses on speed. If you reluctantly start in second gear, it will not only increase the load on the engine, but also cause early wear of the clutch. Therefore, regardless of the displacement of a car, you should start in first gear.

5. To shift gears smoothly, two things must be done: first, the vehicle speed reaches the speed range of the gear being shifted; second, when lifting the clutch, lift it to the "linkage point" and pause (not slowly). , but stop!), and at the same time, a little bit of gas, until you feel the car has forward force, then gently lift the clutch. This operation is smooth, smooth and without jitter.

6. Apply the foot brake accurately. In order to ensure that the foot brake is applied correctly in an emergency, the position of the right heel must be fixed. With the heel as the center of the circle, press the foot brake forward with the ball of your foot and press the accelerator to the right. Usually, whenever there is a slight problem on the road surface, immediately put the sole of your right foot on the foot brake pedal and enter the preparation state to ensure that everything is foolproof!

7. The engine generates traction when refueling with gear braking, and the engine generates braking force when braking with gear, and can control the synchronization of the two drive wheels to prevent deviation during braking. What is particularly important is that the assist force of the brake booster will be greatly reduced when in neutral. Therefore, you must apply the brakes in gear under any circumstances. When the car is about to stop, depress the clutch and return to neutral to prevent the fire from being extinguished.

8. Check the rearview mirror before braking. Check the distance of the car behind you before braking. If it is too close and there is still a certain distance between you and the car in front, brake slightly to avoid a rear-end collision with the car behind you.

9. Always keep track of the foot brake condition. Tap the foot brake before speeding up on the road. Tap the foot brake lightly after driving for a long time. Tap the foot brake before going downhill. Tap the foot brake lightly before approaching intersections or intersections. Foot brake. Always be aware of the foot brake condition. If any abnormality is detected, immediately use the downshift and hand brake to slow down and stop.

10. Danger at bus stops After a bus pulls over to the stop, passengers often get off the bus and run hurriedly to the other side of the road. Some buses do not turn on the turn signal when leaving the station and suddenly go on the road.

11. It is dangerous if the vehicle in front suddenly gives way. While driving normally, if the vehicle in front suddenly gives way, do not overtake. An emergency may occur ahead.

12. Don’t get close to cars parked on the roadside. Cars parked on the roadside may open their doors at any time. When driving, keep a safe distance from any car on the roadside. If you can't avoid it, blow the whistle and slow down to pass.

13. When driving in the middle of the road in a two-way mixed traffic lane, try to stay as far away from bicycles and pedestrians on the roadside as possible, and lean toward the middle of the road, because the cars on the opposite side can see each other, and the cars on the roadside can see each other. Pedestrians and bicycles face away from you, so be sure to keep a safe distance!

14. When overtaking, reduce gear and increase speed while overtaking, you must make a prompt decision and do not hesitate or delay. Look for the empty seat and quickly increase your speed to overtake. If the load of the car is heavy, reduce the gear by one gear and then refuel to increase the traction of the engine and achieve overtaking. Overtaking will definitely consume fuel and cars, and will only increase the risk. It is best not to overtake if you can.

15. Five places where you cannot overtake when driving on non-expressways: ① You cannot overtake on curves, ② You cannot overtake on slopes, ③ You cannot overtake when crossing a bridge, ④ You cannot overtake when there is an intersection ahead. ⑤ You cannot overtake oncoming vehicles within 200 meters from the opposite side. 16. 4 things not to follow a car: ① Don’t follow an out-of-town car and suddenly stop to ask for directions; ② Don’t follow a long-distance bus and suddenly stop to pick someone up; ③ Don’t follow a taxi and suddenly wave and stop; ④ Don’t Follow the big truck. Suddenly the police stopped.

17. Be sure to slow down at intersections. Observe that you must slow down in advance at all intersections. Even if the light is green, you must slow down! Beware of cars coming from across the road running the red light and forcing through the intersection at high speed. If you are walking to the middle of the intersection, how do you avoid it? Have you all seen the traffic surveillance video broadcast by CCTV? The more dangerous it is at night!

18. Turn left at an intersection and make a big bend. When a car makes a left turn at an intersection, many drivers have the habit of taking a shortcut and driving directly over, occupying the left lane. If there is a car rushing in the left lane, it is dangerous!

19. Rules for cornering: slow down before entering the curve, and then accelerate after halfway through the curve, which is fast and stable. If you enter a corner too quickly and then apply the brakes, it is easy to spin or roll over.

20. Honk the horn with caution. Sudden honking may cause pedestrians to panic and run around. Especially when there are children crossing the road. You should slow down or stop and wait.

21. Honk when you can’t see. When driving, if your sight is blocked and you cannot see the road ahead, for example, there are tall buildings and walls at the corners of the road, there are building fences blocking the way, or you must slow down at sharp turns on the mountain road. , whistle. If necessary, use high beam to remind the other party to avoid. Be prepared for people or cars to suddenly run out there!

22. In high-speed emergencies, the steering is extremely sensitive when driving at high speed with only the brakes applied. A slight movement will cause a large steering effect. If an emergency occurs, turning the steering wheel using your usual technique is quite dangerous! Therefore, if an emergency occurs while driving at high speed, it is better to just apply the foot brake to slow down, rather than turning the steering wheel randomly to increase the risk.

23. Water accumulation on the highway. There is often water accumulation on the highway after heavy rain. If you cannot avoid it, hold the steering wheel firmly when passing by and keep driving in a straight line at a constant speed. Never make any steering or braking movements!

24. When going downhill or downhill in gear, you cannot use the foot brake to slow down for a long time, because the brake pads will heat up, be damaged, and fail. You should select low-speed gear 3 or 2 in advance to limit the speed going downhill.

25. Delayed stalling If the car is driven at high speed for a long time, the engine is in a high temperature state. If it is stalled immediately after stopping, it will cause damage to the engine. The correct way to turn off the engine is to let the engine run at idle speed for about two minutes and then turn off the engine.

26. Steering wheel locked The "steering wheel locked" phenomenon is a protective function. After parking and turning off the engine, pulling out the key and then turning the steering wheel, the steering wheel will be locked, which has a simple anti-theft function. The way to release it is to insert the ignition key, twist the key to ignite and turn the steering wheel at the same time, it will unlock naturally.

27. The engine is designed to run at a higher speed. If it works at low speed for a long time, it will cause insufficient combustion, accelerate carbon deposition, and further cause insufficient combustion. You may wish to frequently increase the speed when driving to let the high temperature burn away the carbon deposits.

2. Parking skills There is technology and art in parking.

1. Basic Principles of Parking When parking, you must consider the convenience of your own entry and exit, the convenience of others, and possible accidents.

2. If you wait for a signal to stop for more than one minute, you should turn off the engine, which is in line with fuel saving and environmental protection. If you wait for the signal to stop within one minute, you can leave the engine off, put the vehicle in neutral, or apply the handbrake, but you must not shift the vehicle into gear.

3. Turn on the turn signal when pausing on the roadside. When temporarily parking on the roadside, be sure to turn on the turn signal in advance and observe the rearview mirror to make sure there are no cars or pedestrians before stopping. The parking location must allow parking without affecting the passage of other vehicles and pedestrians.

4. When starting on the roadside and turning on the turn signal, when you stop on the roadside and then drive again, you must fully observe the road conditions. Not just looking in the rearview mirror, but turning your head. After everything is normal, turn on the turn signal, sound the horn, and get on the road.

5. When pausing on the road, don’t get too close to the car in front of you. When you are stuck in a traffic jam or waiting for a signal light, you should at least leave a distance that you can break out of, in case the car in front breaks down and you are caught in the middle and cannot get out. .

6. No matter where you park, park the car with the front of the car facing out. Firstly, it is convenient when walking, and secondly, it has anti-theft function. If a car thief only has the chance to steal one car, he will steal it with the front facing in.

7. When you park your car in the open to visit relatives and friends temporarily at night, choose a bright, spacious, barrier-free, and far-sighted place to park, and never hide in a dark corner. If you park for a long time or all night, you must enter the parking lot.

8. It is not safe under the windows of high-rise buildings. Some people dump garbage and throw bottles from upstairs. Flower pots and advertising stands upstairs will fall when there is strong wind. When parking, you should stay away from these dangerous areas, such as parking in The windowless building is under the gable.

9. Don’t put anything in the car. Keep items in the car well. There should be no things that others are interested in that can be seen from outside the car. If you leave an empty leather bag, the windshield may be smashed!

10. Tips for parking along the roadside. When there is only one parking space along the roadside, you can only choose to reverse into the parking space. Method: Drive forward so that the rear of your car is aligned with the rear of the front car. The two cars are 1 meter apart and stop. Turn the steering wheel fully to the right and back away slowly at a 45° angle. When the front of your car is in line with the rear of the car in front of you, quickly turn the steering wheel fully in the opposite direction and back up slowly, and the car will basically be able to stop.

11. Lateral parking skills on the roadside: drive forward until the rear of your car is in line with the right side of the front of the car on the right, and the two cars are 1.5 meters apart. Turn the steering wheel fully to the right and back away slowly. When the rear of the car enters the gear, quickly return the steering wheel and quickly observe the left and right rearview mirrors to adjust the left and right distance of the car. Use the cars on both sides or the lines on the ground as a reference to correct your direction and retreat to the parking space. ("Strike in the full direction" means the maximum amount. The time for hydraulically assisted hitting to the bottom should not exceed 15 seconds. It usually does not take this long. If it takes a long time to hit the bottom, you can bring it back a little and then hit again. , repeat the operation.) 12. When parking in a parking lot, the car is often reversed, with the front of the car facing outward.

13. If you need to park on the expressway under special circumstances, you must park in the emergency lane on the far right, turn on the double flashing lights, and place the triangle sign 150 to 200 meters behind the car. Don't be lazy. Within 50 meters, it means there is no release. If there is a situation ahead that requires queuing to park, all personnel should temporarily leave the vehicle and retreat outside the guardrail to prevent rear-end collisions with oncoming vehicles.

14. Parking on the roadside on an uphill slope. If there is a curb on the side of the road, drive the car close to the curb, turn the front wheels to the left at a certain angle, stop the car, turn off the engine, shift to 1st gear, and tighten the handbrake. Let the rear of the right front wheel be close to or close to the curb to prevent the car from sliding down the slope. If there is no curb on the roadside, turn the front wheels to the right at a relatively large angle to prevent the car from sliding down the slope and into the center of the road. If there are bricks and stones available on the roadside, bring them over and plug them. Don’t forget to return it to where it came from when you leave.

15. When parking on a downhill roadside, if there is a curb on the side of the road, drive the car close to the curb and turn the front wheel to the right at a certain angle so that the front of the right front wheel is close to or close to the curb to prevent the car from driving. Smooth down the slope. Then stop the car, turn off the engine, engage reverse gear, and tighten the handbrake. If there is no curb on the roadside, turn the front wheels to the right at a relatively large angle to prevent the car from sliding smoothly down the slope and into the center of the road. If there are bricks and stones available on the roadside, bring them over and plug them. Don’t forget to return it to where it came from when you leave.

3. Tips for using car lights. All lights on the car are powered by batteries, and the electricity in the batteries is converted from gasoline. Ineffective use of car lights wastes gasoline, damages bulbs, and damages lamp housings. The light bulb is a wearing part and should be replaced with spare parts at any time.

1. Night driving lights, commonly known as "headlights". Headlights have two forms: high beam and low beam. Use low beam on roads with street lights in urban areas, and high beam when driving on roads without street lights or highways. When passing through an intersection or overtaking, the high and low beams alternately change to provide prompts.

2. Night traffic lights, commonly known as "small lights", are used to display the width and length of the vehicle body at night to remind other vehicles and pedestrians to see them. When you can't see clearly behind you from the rearview mirror, you should turn on the small lights, including on rainy days.

3. The turn signal should be turned on about 100 meters before the turning intersection. Driving too late will cause following vehicles, oncoming vehicles, and passing pedestrians to be unprepared and make mistakes while busy. When waiting in line at a traffic light intersection to turn, as long as you are not first in line, there is no need to flash for a long time. Wait until the car can turn and move before flashing again. Otherwise, it will cost electricity and lights, and the driver behind you will be upset.

4. Brake lights Brake tail lights are used to inform the car behind you to slow down or stop. If there is a fault, it can easily cause a rear-end collision. The power of the double tail light bulbs of the brake lights is many times greater than that of ordinary small light bulbs, which will generate high temperatures. If the foot brake is pressed for a long time, the brake tail lights will stay on for a long time, affecting the service life and wasting electricity.

5. Fog lights can help drivers improve visibility in foggy days, notify oncoming vehicles, avoid each other, and meet vehicles safely. Therefore, when driving in foggy weather, fog lights must be turned on and must not be replaced by small lights. The power of fog lights is usually 55W/light, which is similar to headlights, but the heat dissipation space is far less than that of headlights. Therefore, be sure to turn it off immediately after parking to prevent overheating and damaging the lampshade.

IV. Fuel-saving Tips 1. Control the optimal speed when driving. Generally, the engine speed of an EFI vehicle is most suitable around 2200-2500. No matter which gear it is in, keep the engine rpm at about 2200-2500. If the speed is too low, the car will not be able to move, and it will consume more fuel and damage the engine; if the speed is too high, it will increase the ineffective fuel consumption and also damage the engine.

2. Maintain the best speed and the most fuel-efficient driving state is to drive in a straight line at a constant speed. The most fuel-efficient speed for small-displacement cars is 60-80 kilometers per hour, and for medium-displacement cars is 80-100 kilometers per hour.

3. Control the shifting speed. When shifting, add a little more oil than normal driving, so that the speed reaches a little more than 2,500. If you shift gears when the speed is lower than 2000 rpm, the speed will still drop after shifting, and you will feel like you are out of gear. You have to refuel to get it back, which will consume more fuel.

4. Don’t change lanes or overtake. Sometimes you change lanes, overtake, suddenly refuel, and suddenly brake. This wastes gas and traffic, and the risk factor increases several times. It’s very unworthy and unworthy. necessary. When driving your own car, remember to stay on the same lane as possible, do not overtake, and keep driving at a medium and constant speed to be safe and save fuel.

5. Don’t brake hard. If you need to stop in front of you, you should stop the gas in advance and coast to slow down in gear instead of rushing to the front and braking hard. Braking actually consumes precious gasoline. The harder you brake, the more it is wasted.

6. Take good roads, and take roads with fewer cars. If you want to take a shortcut, it will cause traffic jams, the speed will be too low, and the fuel consumption will be high. It is better to find a long way around but with good roads. , save fuel and cars.

7. Full tire pressure to ensure normal tire pressure. Tire pressure that is too high or too low will increase fuel consumption. The pressure of car tires must be strictly in accordance with the requirements of each vehicle manual. In order to prevent the road surface from being overheated in summer, especially when the tires heat up when running long distances, the gas in the tires expands and the pressure increases a lot. You can slightly reduce the air pressure by 10%.

8. Half a tank of oil reduces the weight of the car body, which means reducing fuel consumption. Don't run around the city with a full tank of gas, this is "fuel consumption"! Considering that the gasoline pump is installed in the fuel tank and relies on gasoline to dissipate heat and cool down, it is best to keep half a tank of fuel if you are not traveling far. At the same time, the interior of the car must be streamlined to reduce weight and save fuel. 5. Snow driving skills There are two main driving difficulties in the cold winter in the north. One is the low temperature and difficulty in starting; The road surface is slippery and it is easy to lose control of steering and braking. When the temperature is around -20°C, I have never encountered any difficulty in starting an EFI car parked in the open air. However, when the temperature is close to -30°C, it often fails to start, especially when the battery is low.

1. Clear frost and snow before getting in the car. Before getting in the car, clear the frost and snow on the front and rear windshields, lampshades, and rearview mirrors, and clean the snow on the soles of your feet. The important thing is that the foot brake pedal should not be slippery on ice or snow. Then check the antifreeze, oil, and tires.

2. In severe cold weather, start the car in neutral and depress the clutch without stepping on the accelerator. The ignition should be instantaneous without ignition. The interval between each time should be more than 10 seconds and at least 3 times. The purpose is to activate the lubrication system. After igniting the engine, keep the clutch in neutral and idle to warm up the car. Release the clutch after 1 minute. If it still doesn't hold, step on it for a while. After the fire is ignited, release the clutch and continue to warm up the car at idle speed for 1-2 minutes. If you still can't start the fire after working for a long time, and the battery is out of power, stop turning it on, the battery can't stand it! There are three options: one is to borrow the car battery to start the ignition, the other is to replace the battery, and the third is to tow it to the maintenance department.

3. Starting on icy and snowy roads. Starting on hard and slippery icy and snowy roads, engage 2nd gear, lower the accelerator, lift the clutch to the linkage position, pause briefly, and lift up slightly. If the car moves, Continue to lift it up, slowly refuel, and drive away. If the wheel slips and you cannot move, depress the clutch pedal, shift to 1st gear, then lift it and depress it again to let the car rock back and forth, gradually increasing the amplitude of the rocking. After a few times, when the car rocks forward, lift the clutch pedal and drive away. If you still can't walk, check the distance behind the car, back up a little, and try again. You will usually succeed. Finally, if you still can't walk, you have to clean the ice and snow under the driving wheels, or put sand and soil on them, which is a little troublesome.

4. Starting on soft snow. When the soft snow that has just fallen reaches more than 10 centimeters, stop the car and then start again. You should also engage in 2nd gear, use a small accelerator, slowly lift the clutch, and start slowly. The key is to let the wheel turn slowly and never turn it too fast. If you operate it normally, the wheels will slip and spin, making you unable to move. If the snow is slippery and you can't walk, step back a little and try again. If you really can't walk, you need someone to push it, or clear the snow under the driving wheels and put sand or other anti-slip materials on it.

5. When driving at low speed, control the speed at about 20-30 kilometers on an uncertain smooth road. When entering a normal road with ruts, the speed can reach 40 kilometers per hour. When you see the black color after snow removal, You can drive normally on the road, but you should always pay attention to ice and snow that may suddenly appear.

6. Refuel slowly. When driving on slippery, icy and snowy roads, refuel gently and slowly. Otherwise, the wheels will spin and slip, causing the vehicle to lose control of direction.

7. When driving on icy and snowy roads without neutral gear, sliding in neutral gear is not allowed. Especially when going downhill in Xialing, be sure to shift to a low gear in advance and drive steadily.

8. Slow down smartly When driving on slippery, icy and snowy roads, when slowing down from high speed to low speed, do not stop accelerating or apply the foot brake! You can only slow down by gradually downshifting, and use the braking force of the engine's low gear to slow down. When the speed is very slow, you can stop the gas, shift into neutral, and apply the foot brake. If you don’t know how to brake on icy and snowy roads and lift the accelerator and apply the foot brake, the consequences will be disastrous!

9. When turning slowly, you must first slow down, then turn the steering wheel slowly and increase the turning radius appropriately. Steering operation should be even and gentle. If the steering wheel is turned sharply, instead of turning, the steering wheel will slip and direction control will be lost.

10. Use grooved wheels. Choose grooves or ruts along the ice and snow road. At least one wheel should run in the groove or rut to prevent sideslip. Never go to places where there are no ruts covered by heavy snow.

11. Keep your distance. On icy and snowy roads, cars may slip randomly at any time. You should try to stay away from other people and cars to take precautions.

12. What to do if an out-of-control skid occurs. To get rid of an out-of-control skid on icy and snowy roads, instead of pressing the brakes, tap the accelerator and use intermittent refueling to speed up, allowing the drive wheels to find their point of action and restore their driving ability, thus restoring the car. The ability to control direction.

6. Driving skills in rainy days There are three main dangers of driving in rainy days. First, rain and mud will cause the wheels to slip. Second, water will enter the exhaust pipe and stall. Third, rain will cause the braking system to malfunction.

1. Brake in the rain in advance. The maximum braking distance on muddy roads can reach 3 times that of normal roads! If the brakes don't work in the rain, slow down and brake early.

2. Do not lower the tire pressure. Some people lower the tire pressure every rainy season, hoping to increase the contact area between the tire and the ground to prevent slipping. Doing so is just the opposite! Increasing the contact area reduces the pressure of the tire on the ground per unit area, weakening the force that displaces the water film between the tire and the ground, making the tire more likely to slip. Therefore, lowering tire pressure will not prevent slipping, while increasing tire pressure will prevent slipping.

3. It is easier to slip when the ground is not wet. The tread pattern can effectively repel the water film, but it cannot effectively repel the mud film. When it first rains, the dust on the road has not been washed away by the rain. After absorbing the rain, the dust turns into a colloidal mud film, making the tires more likely to slip. So be careful when it just rains and the road is not wet.

4. Stop the car due to unclear vision. Driving in heavy rain and having unclear vision is the biggest hidden danger! Even if the wiper swings at high speed during a heavy rain, it will not be able to clear the rainwater on the glass, making it impossible for you to see clearly ahead. At this time, you'd better pull over to the side of the road and wait, turning on the double flashlights at the same time.

5. You can’t get out of the car during thunder. Even if lightning strikes the car, the current will be transmitted to the ground through the surface of the car body, making the car safe. However, all car windows must be closed tightly and the radio antenna must be stowed away.

6. When passing through waterlogged roads, observe the driving conditions of other vehicles and ensure to avoid obstacles such as deep pits and hidden traps. When water floods the exhaust pipe, prevent water from entering the exhaust pipe. To do this, you must shift into low gear before entering the water, hold the throttle steady and drive straight through at a constant speed. To prevent water from entering the exhaust pipe, do not collect oil after entering the water; to prevent the driving wheels from losing traction, do not change gears midway; to reduce resistance during travel, keep driving in a straight line at a constant speed. If the fire is extinguished due to water entering the exhaust pipe, or even water entering the cylinder, you must never start the fire again and must rely on rescue. After a car passes through a waterlogged road or drives in a heavy rain, water entering the brake pads can cause the brakes to fail. You can use the method of pressing the accelerator and foot brake at the same time while driving at low speed to allow the brake pads to heat up and drain away the moisture.

7. Water wading skills for automatic transmission cars. The key points for wading automatic transmission cars into water when the water depth exceeds the exhaust pipe are the same as for manual transmission cars. The specific operation is: shift to 2nd gear, step on the accelerator with your right foot, and fix a larger amount of oil until you leave the water. Once you need to slow down, apply the footbrake with your left foot to slow down. By doing this, the exhaust gas will not get into the water, and the vehicle can smoothly drive through waterlogged roads.

8. Passing through muddy areas When passing through muddy areas, one is to prevent slipping and the other is to prevent sinking, so you must follow the ruts of the vehicle in front. Before entering a muddy area, shift to a low gear. Do not shift gears midway. Drive in a straight line at a constant speed. If you change gears midway, the car will instantly lose power and stop, making it difficult to start again. If you get stuck in the mud, don't step on the accelerator rashly, otherwise driving the wheels will only make the car sink deeper and deeper.

If there is nothing else to pad the wheels, you can inflate the skidding tires until they are almost flat, making the tires soft and deformed to increase the friction of gripping the road. After starting the engine, put it in 2nd gear, half-clutch, refuel, and start slowly, and most of the time you can pass smoothly. If only one tire is slipping, gently apply the handbrake and increase the accelerator. Due to the effect of the handbrake, the spinning wheel will stop rotating, and the wheel on the other side increases the driving force, making it possible to easily drive out of the muddy area.

7. Prevention skills when going out Driving far away has traffic safety problems and social security problems.

1. Keep backup keys on your body to prevent loss, and keep them with you at all times; copies of relevant documents should be kept separately.

2. Refuel carefully and only go to gas stations of Sinopec and PetroChina.

3. Be cautious about food and accommodation, refuse any food or drinks from strangers, and do not come into contact with any items or cigarettes from strangers. Do not eat or stay in roadside shops.

4. Anti-robbery while driving. If you encounter an intentional collision while driving normally, do not get out of the car, lock the door, call the police on your mobile phone, and wait for the police. If the other party takes drastic actions, you should quickly drive away from the scene and continue to call the police. When pausing or driving slowly, lock the doors and raise the windows to prevent theft. Criminals often take the opportunity to signal to the car or knock on the windows. When the driver thinks there is a problem with the vehicle and gets out of the car to check, the criminals take the opportunity to steal the property in the car. Criminals may reach out to grab the car through the lowered glass window, or directly open the door to grab it.

5. Prevent robberies when parking. When parking near remote scenic spots or temporarily shopping, observe the surrounding situation. If there are signs of idle people or bad people, do not put out the fire and park, let alone get out of the car. If necessary, quickly Drive away. Be sure to park your car in the parking lot wherever there is one. If you need to park temporarily and there is no parking lot, please leave someone in the car and lock the door.

6. Parking anti-theft When parking in the parking lot of your accommodation at night, you must take out all the items in the car, including the items in the trunk, in front of the guard. Many hotel guards and security guards are on guard and committing theft. Someone parked his car at a hotel in Beijing and packed his suitcase after returning from shopping. The guard saw items of interest in the car. The door was pried open at night and all the items were lost.

7. Before starting to prevent robberies and getting in the car, observe from a distance to see if there are any unscrupulous people around the vehicle. If there is anything suspicious, do not get close to the vehicle for the time being. Before getting out of the car, walk around the vehicle to check whether there are any oil or water leaks on the vehicle's exterior, tires, and under the vehicle. Pay special attention to the road surface you are about to pass, which may contain sharp foreign objects such as nails and glass. After getting in the car, immediately lock the door and leave as soon as possible.
