What should I pay attention to when driving in rainy days?

In rainy days, in addition to driving carefully, you should turn on the wiper in time, and turn on the low beam and anti-fog lights when the weather is dim. If the front windshield is frosted, turn on the cold air and blow it on the front windshield; If there is frost on the rear windshield, turn on the rear windshield heater to eliminate the frost as soon as possible, so as not to see the vehicles behind you clearly.

2. Prevent the wheels from slipping.

When driving in the rain, "lubricant" is formed between the rain on the road surface and the tires, which makes the braking performance of the car worse and easy to slip. Therefore, the driver should hold the steering wheel with both hands in balance, keep driving in a straight line at a low speed, and when turning, he should step on the brakes to slow down to prevent the vehicle from slipping due to tire locking. If the front wheel slips, correct the direction in the opposite direction of the slip; If the rear wheel slips, correct the direction to the slipping side, and never hit the opposite direction.

3. Drive slowly in low gear.

Experienced drivers know that no matter the width of the road and the condition of the road surface, try to use the second or third gear when it rains, and the speed is not more than 30 kilometers or 40 kilometers per hour. Always pay attention to the distance between the cars in front and behind, and be prepared to take various emergency measures in advance. If you need to stop, slow down as early as possible 100 meters or so, and brake lightly, so that the rear car has enough emergency preparation time to avoid collision or rear-end collision due to excessive braking.

4. Prevent wading into the car

When the car passes through the road with stagnant water, or under the overpass, deep tunnel, etc. The first thing to do is to stop and check the depth of the accumulated water. The simplest way is that the water depth should not exceed the height of the exhaust pipe. If you exceed the height, you should choose another route to bypass. If the water depth is only half of the tire, you can put in first gear, keep the throttle steady, and go straight at low speed in one go. Don't stop, shift gears or make sharp turns in the middle, so as to prevent the vehicle from stalling and the engine from being damaged due to operational errors.

5. It is not advisable to accelerate overtaking.

When driving in rainy days, always pay attention to the speed and direction of the car ahead, and never accelerate overtaking because of the slow speed of the car ahead. Especially in expressway, due to the high speed of each lane, the driver's visual angle is narrowed and the road surface is slippery. When crossing the line and forcibly overtaking, it is easy to cause the wheels to slip and scrape with other vehicles, resulting in accidents such as vehicle rollover.

6. avoid hitting people while driving

Because pedestrians are holding umbrellas in the rain and cyclists are wearing ponchos, their vision, hearing and reaction are limited, and sometimes they turn violently in order to catch up with time and compete to change trains. Often, when vehicles approach, they panic and slip, which makes drivers unprepared. In this case, drivers should slow down, honk more, patiently avoid, choose a safe place to park when necessary, and must not compete with pedestrians and bicycles to prevent pedestrians from being knocked down.

7. Self-rescue method for cars stuck in mud pits

When driving on a rainy day or a dirt road in the country, the wheels often get stuck in the mud. Once this happens, you can put in first gear or reverse gear and tentatively step on the accelerator slowly. When the car can move forward or backward, you should keep the accelerator pedal position unchanged and drive out of the muddy road at a low speed. If the car can't move back and forth, stones, bricks, boards or branches can be placed in front of and behind the driving wheel to increase the adhesion between the wheel and the ground, so that the car can drive out of the mud pit smoothly.

Secure parallel technology

1. When it rains, you must be careful to overtake because the rearview mirror has a bad view. When you are not sure, don't merge or overtake easily.

When driving, be sure to turn on the light. Car owners who are not used to playing turn signals when overtaking in parallel should also pay attention. Before merging, turn on the turn signal and see if the car behind responds. Don't overtake first if the car behind you flashes its lights or honks its horn.

3. If you still can't confirm the rear situation, you can also open the window and quickly turn your head to look at the rear. But you should slow down first to avoid hitting the obstacle in front.

4. When it is confirmed that you can merge safely, you should merge smoothly immediately, so as not to affect the driving of other vehicles in hesitation.

5. Don't overtake from the right, especially super-large cars. Due to the height of a large car, when the car is close to the right side of the large car, the driver may not see it in the rearview mirror.

Must slow down.

When driving on dry roads, the speed increases, and the adhesion between wheels and roads (commonly known as "grip") hardly changes. In rainy days, when vehicles are driving on slippery roads, with the increase of vehicle speed, the grip of wheels drops sharply, which is easy to cause "water slip". Don't step on the brake pedal or slam the steering wheel at this time.

(1) The relationship between vehicle speed and safety on wet roads.

When speeding up in rainy days and a "water film" is formed between the tires and the road surface, the steering and braking of the car will be in danger of failure, just like a thrilling water skateboard ...?

(2) Driving in rainy days is not only an obstacle of sight, but also an unsafe driving factor. Because the road is slippery after rain or rain, the wheels are easy to slip, which adds various difficulties to the driver's operation and can not be ignored.

(3) Due to poor eyesight, children may not be found in time, so it is necessary to slow down.

(4) Pedestrians may not realize that the car is approaching, so they must keep a safe distance and slow down.

(5) In order to avoid water accumulation, pedestrians may walk in the driveway and must slow down.

Driving two killers

In rainy days, the main factors that directly affect driving safety are visibility and road conditions.

In addition to visibility and road conditions, you should also pay attention to maintaining a reasonable distance when driving in rainy days.

Visibility refers to the farthest distance in the horizontal direction that people can see through the air with the naked eye. Rain falls in rainy days, which makes the windshield and rearview mirror blurred, and the reflection of wet road surface greatly reduces the visibility. The road surface condition directly affects the friction (adhesion) coefficient of wheels, thus affecting the braking performance of automobiles. When driving on a dry road, the speed increases, and the adhesion between the wheels and the road hardly changes. In rainy days, when vehicles are driving on slippery roads, with the increase of vehicle speed, the grip of wheels drops sharply, which is easy to cause "water slip". Don't step on the brake pedal or slam the steering wheel at this time.

Presumably, everyone who rides a bicycle knows that on rainy days, the rain falls on the window glass, and the line of sight in front of the car is quickly blocked, and vehicles, pedestrians and scenery become blurred. Turn on the wiper at this time, and the front of the car will be clear. Therefore, if you drive a vehicle in rainy days, it is very unfavorable for driving safety if you don't use the wiper or the wiper can't work normally. Therefore, before the heavy rain comes, the owner should check whether the car wiper can work normally. However, it needs to be clear: on a rainstorm day, the rapid rainstorm hits the windshield, and even if the wiper moves faster, it is difficult to scrape off the raindrops, which will affect the driver's sight. In order to ensure driving safety, drivers should stop immediately.

Make sure the rearview mirror is clean.

Rainy days make the rearview mirror clearer

When driving in the rain, the rearview mirror is often blurred by the rain. Only the general outline of the rear car can be seen, which is E68A 84E799Be5Baa63133365653838. You can't tell the distance clearly, and you can't even judge the rear situation at all, which brings great difficulties to drivers and also causes certain safety hazards. Here, the insiders introduce several methods to improve the line of sight of rearview mirrors in the rain for your reference.

■ Installation of flashing: economical and practical.

There are generally two kinds of rain shields, one is attached above the rearview mirror, and the other is inserted in the gap between the rearview mirror and the frame. I suggest you choose the former, because it is not only convenient to install, but also can be removed directly if you want, and then do some glue removal treatment. If it is the latter type of rain cover, it is not easy to judge the thickness of the rain cover before unpacking. Sometimes the flashing is too thick, which will hinder the rotation of the rearview mirror after it is inserted. The price of shelter from rain is generally in 20 yuan -50 yuan, which is relatively economical.

When the rain is not very heavy, the rain shield is still very useful, but when it is windy and rainy, the role of the rain shield will be weakened, but at least one third of the rearview mirror can be guaranteed to be clear.

■ Retrofitting the heated rearview mirror: good effect and high cost.

The rearview mirrors of some high-profile cars have heating function, which can evaporate water vapor, even when driving in rainy days. Modifying or replacing the rearview mirror with heating function has a good effect, but the cost is also relatively high.

The rearview mirror of some models can be replaced directly. If you choose to install this kind of heated rearview mirror, the wiring in the car is reserved in advance, and there is no need to make any changes, but the cost is relatively high, about 3000 yuan.

If you can't choose to install it, you can also modify it yourself and install a thick heating wire in the rearview mirror. This modification generally needs to change some original lines in the car.

Of course, the method of self-modification does not apply to all cars. Because the heating wire needs to be heated, if the motor gear in the rearview mirror is plastic instead of iron, then this modification cannot be made. Some low-displacement vehicles are not suitable for this modification, because the total power of two rearview mirror heating wires is equivalent to that of a rear window defroster. Installing a low-displacement car will lead to insufficient power.

■ Applying waterproof agent: Different quality has different effects.

Some waterproofing agents can be bought in the market, which can keep the surface of rearview mirror free from water. Some products need about 50 yuan per bottle. However, from the practical use, the effect of general waterproofing agent is not very significant. Of course, there are some good effects, such as some imported waterproofing agents, which can last for 1 month once. The heavier the rain, the clearer the mirror. However, this waterproof agent is more expensive, nearly 1,000 yuan per bottle.

■ Put detergent: Emergency measures are generally effective.

There is a temporary method, which is to polish some car wax on the mirror, or rub some detergent and soapy water, which can keep the effect for a day or two. However, light rain is still easily adsorbed on the mirror, and the effect is relatively better when it rains heavily.

■ Change the rearview mirror with large field of view: it is very easy to use.

For vehicles with wipers and large rear windows, it is also useful to replace the interior rearview mirror with a large angle rearview mirror.

Operating essentials of wading driving

Preparation and protective measures before wading

Before the car wades, it is necessary to carefully check the water depth, flow speed, bottom, width and road conditions of entering and leaving the water area to judge whether it can pass safely. If the water depth exceeds the maximum wading depth of a wheel or car, it is not advisable to risk wading. In fact, as long as the water level reaches two-thirds of the front bumper or tire, it is very dangerous to wade again.

When confirming that the structure of the car you are driving can pass, you should generally choose the section with the shortest distance, the shallowest water level, the slower water flow and the firmest water bottom. If you must sail in deep water, please make the following preparations first.

1. Wrap the distributor, high voltage line, ignition coil, etc. Use tarpaulins or plastic bags, and try to raise the position of the battery (such as in the cockpit or carriage).

2. The fuel filler of the fuel tank, the hole of the dipstick and other vent holes on the engine and drive axle should be blocked with waterproof materials.

3. If the water level is close to the maximum wading depth of the car, you should tie a wide wooden board to the front bumper, and then drive at a low speed, so that the water in front of the car is pushed away by the wooden board, forming a shallow water area at the engine to prevent the ignition system from being soaked in water and losing its function.

4. If possible, increase the weight of the car as much as possible to reduce the buoyancy effect of water on the car and increase the adhesion of the wheels.

Operation methods and precautions when wading

1. When the car wades, it should be carried out under the condition that the engine is running normally and the steering and braking mechanisms are sensitive and reliable. You should put the low gear into the water smoothly, avoid slamming on the accelerator or rushing, and prevent the spray from splashing into the engine and stalling.

2. Keep the throttle steady when driving, keep the power of the car sufficient and stable, and try to avoid stopping, shifting gears or turning sharply, especially when the underwater road is muddy.

3. Look far and near, try to see the fixed target in the distance, hold the steering wheel with both hands and go straight ahead. Don't look at the water flow or spray, so as not to confuse the line of sight and create illusion, which will lead to the vehicle deviating from the normal wading route and causing accidents.

4. When more than one vehicle wades, it is absolutely forbidden to enter the water at the same time. The vehicle behind can only be launched after the vehicle in front reaches the other side, so as to prevent the vehicle in front from stopping due to failure, forcing the vehicle behind to stop in the water, resulting in a dilemma.

5. Finally, remind the owner that the car must not be started immediately when it is turned off in water, so as to avoid serious damage to the engine, and measures should be taken to tow the car to a safe place with less water as soon as possible.

Safety inspection after wading

1. After wading, you should choose a wide and safe place to park, take off the waterproof bandage, check whether the engine ignition system is wet, and wipe the wet electrical parts with a dry cloth to prevent short circuit or open circuit.

2. Check whether there is water in each gearbox, whether there is drift and blockage between the radiator of the water tank, whether the tire is damaged, and whether there is water grass winding under the chassis. , and clean up the vehicle in time.

3. Start the engine, let the engine idle for a few minutes, reach the normal temperature, and dry the water and moisture on the engine. After confirming that the technical condition of the automobile is good, first drive at a low speed for a certain distance, and consciously lightly step on the brake pedal several times, so that the brake shoe and the brake hub contact and rub to generate heat energy, so that the residual moisture in the brake is dried and evaporated to ensure good braking performance.

4. once the owner encounters stagnant water, it is best to go to the garage and professional after-sales service station for repair, and never go to the roadside shop for cheap repair.

The water depth should not exceed the exhaust port.

The main problem encountered by cars in rainy days is passing through deep water. Remind the owner to pay special attention to the water depth. If the water depth exceeds the exhaust pipe or air inlet, the vehicle is easy to die. Another critical point of water depth is about half the height of a wheel, that is, between 25 cm and 30 cm.

Dodge when you see water, or brake immediately to slow down, which is a common problem of many car owners. Drivers in the back don't know how to react when they dodge left and right, which is prone to accidents. In fact, if the water depth is about 15 cm, it has no effect on the car, so you can drive at normal speed without worrying about water ingress or anchoring. When the water depth is about half a tire, first shift to a lower gear, increase the engine speed, stabilize the throttle, and keep the driving speed wading through. If the water depth is more than half a wheel, it is recommended to let the water recede before passing. If you really want to force your way through, you'd better let the trailer tow it.

Pay attention to driving on the expressway.

Rainy days have brought inconvenience to drivers, and accidents in expressway have also increased, so you must pay attention to the speed and distance when driving.

First, ensure the line of sight.

Before driving, the driver should ensure a good line of sight. In rainy days, the rearview mirror is easy to get wet, which leads to blurred vision of the driver. Be sure to dry the rearview mirror, so that you can clearly observe the movement of the vehicles behind you and make a quick response when driving.

Second, detect vehicle braking.

Before starting, the vehicle brake should be detected in time to prevent accidents caused by the failure of the vehicle brake system caused by water inflow.

Third, don't brake suddenly in case of stagnant water.

Slow down when passing through the puddle to avoid water splashing on the glass and blurring the driver's vision. Don't slam on the brakes to avoid water accumulation in expressway, and pay attention to keep the driving direction of the vehicle from changing greatly.

Fourth, don't overtake on the construction section.

Pay attention to the sign in front of expressway, and the construction section will slow down in advance. The line of sight is not good in rainy days, so don't overtake or occupy other lanes easily on the construction section.

Fifth, change lanes quickly.

When overtaking or changing lanes, you should observe the distance between the front and rear cars through the rearview mirror and turn on the turn signal to overtake quickly.

Six, check the vehicle circuit, to prevent failure.

Check the vehicle circuit before starting in rainy days, and deal with the exposed wires in time to avoid short circuit and anchor on the expressway at high speed.

Seven, by the light.

On expressway, in rainy days, you should use high beam and low beam to signal other vehicles, and use light signals to tell the distance between the two vehicles.

Eight, emergency parking should choose a good location.

Emergency parking should choose a position with good line of sight, not close to the bridge, which is prone to fog and poor line of sight. When parking, you should turn on the emergency lights and put a triangle sign next to the car. If possible, you should prepare rain gear.

Five taboos for wading driving

Summer is the traditional rainy season in southern China. The continuous rainstorm has caused car owners and their cars to suffer together. Because of the arrival of the rainstorm, the owner's awareness of vehicle maintenance has to be enhanced. Here are some ways to keep a car in rainy season.

1 car wash protection paint in rainy days

Many car owners think that in rainy days, after the dust on the surface of the vehicle is washed clean by rain, it saves the trouble of washing the car. But in fact, if you don't wash the car in time after the rain, it will do great harm to the car paint, so car cleaning after the rain is more important than ever. Rain often contains impurities and acidic substances. If the vehicle is wet by rain and not cleaned for a long time, acidic substances will corrode the bright film on the outermost layer of car paint, and the paint surface will immediately become eclipsed. In addition, the rain mixed with some invisible asphalt fines, dirt and dust are also easy to adsorb on the paint surface of the car body. These dirt will generate a lot of oxides after being exposed to the sun, which will leave indelible scars on the surface of car paint for a long time. Therefore, it is suggested that car owners and friends need to clean their vehicles in time after the rain.

2 dehumidification and sterilization in the car

Hot and humid weather in summer and rainy season is easy to breed germs, and the enclosed space in the car becomes a hotbed for germs to breed. Therefore, dehumidification and sterilization should be started immediately after the rain stops, especially in families with children.

It is suggested to find a cool and ventilated place and open all the doors so that the moisture in the car can be eliminated in time. Then remove the mat and chair cover from the car, clean it and dry it.

In-car sterilization can usually be carried out by ozone disinfection and photocatalyst sterilization. The general ozone disinfection method is simple in operation and low in price, and this service can be provided free of charge in many places where vehicles are cleaned. The price of photocatalyst is much more expensive, but the disinfection and sterilization effect is also ideal, and the cost is around 300 yuan. The principle of photocatalyst is to decompose harmful substances in the car through free radicals with strong oxidizing power, so as to purify the air. Because it can completely decompose most pathogens, it can effectively inhibit the spread of some pathogens such as enterovirus and influenza. In addition, it can decompose harmful gases in the air to achieve the effects of purifying the air, deodorizing and mildew prevention. Air conditioners often smell moldy after rain. In order to eliminate this smell, there is a simple way, that is, turn up the warm air of the air conditioner to the maximum and use various air outlet modes in turn, about 15 minutes. When the air conditioner works, the temperature of the air outlet can reach 40℃-50℃, so the hot air inside can be evaporated to remove mildew.

3 maintenance station comprehensive "physical examination"

After the heavy rain, no matter whether the vehicle is abnormal or not, it is best to go to the 4S shop for a comprehensive "physical examination". Because some hidden dangers can't be found on the spot, but the potential harm to the car is extraordinary. For example, heavy rain can easily make some leaves, dust and so on. Stick to the drain hole of the cooling system or engine hood. If these pollutants are not cleaned up in time, the working efficiency of the cooling system will be reduced, resulting in mechanical failure. Therefore, after the rain, it depends on the position of the air inlet of the separation part between the engine compartment and the cockpit and whether there is water in the grooves on both sides of the left and right fenders. If there is stagnant water, the air inlet can be washed with clean water to clear the waterway and ensure the best working condition of the vehicle.

After the rain, due to repeated irrigation, the performance of some parts of the car may be affected, which will seriously lead to the failure of the car to open normally. Therefore, after wading in rainy days, even if the engine is running normally, it is recommended to go to the maintenance station in time to deal with the circuit equipment. For example, blow-dry or dry the circuit before starting preheating. In addition, it is important to check the braking system. Because of the strong adsorption of the braking system, rainwater can easily enter the brake fluid, which will affect the braking effect and may seriously cause braking failure. It is recommended to go to a professional repair shop for inspection after the rain to prevent future troubles.
