What should I pay attention to when braking in snowy days?

Don't fill the valve immediately when the weather is cold, because the nose has not been fully lubricated with engine oil. /kloc-Don't start in gear after 0/0 seconds. Brake slowly in snowy days. Don't step on it all at once. It is best to add snow chains to the tires. In addition, pay attention to the viscosity of engine oil. It is better to use thinner oil. Better liquidity. Also pay attention to the coolant. The lower the freezing point, the better.

Precautions for driving in snowy days:

(1) Clean the snow before driving after heavy snow. Before starting the car, clear the snow on the front and rear windshield, headlights and rearview mirrors of the car to ensure that the line of sight will not be affected when driving; It is best to prepare a piece of cotton cloth at hand and wipe the rearview mirror and window glass when parking on the road; When driving, turn on the front and rear windshield defogging switches to maintain a good line of sight. Snow-covered roads will make it difficult for cars to start. In order to enter the driveway smoothly, it is best to move the car back and forth a little or use a snow shovel to clear the snow in front of the car. Step on the accelerator lightly after ignition, and don't idle the wheel, or the wheel will sink deeper and deeper. (2) Warm up the car for a few minutes after starting. Check whether the instruments, steering brake lights and wipers are in good condition and whether the tire pressure is normal, and eliminate hidden dangers in time; Make sure there is no snow or thin ice on the soles when driving. (3) Driving vehicles in snowy days should drive at a low speed and master the safe speed. Keep enough distance from the car in front, and always be ready to brake in advance. We should give full consideration to other people, especially bicycles and pedestrians, who may suddenly fall down or drive on the motorway because of the slippery road. Therefore, when driving through intersections and crosswalks, you should keep a safe distance from pedestrians and non-motor vehicles to avoid rushing. When driving, if the snow is as deep as the axle, you should clear the snow before moving forward. If there is a rut on the snowy road, follow it. When driving according to the rut, the steering wheel must not turn sharply to avoid slipping out of the rut and sinking. If the rut is shallow, you should ride it. When overtaking or giving way, carefully pull over. You should wear colored glasses when driving in the snow. But when the temperature rises and the snow begins to melt, the road surface will become extremely slippery.

(4) Road icing is the most dangerous situation that drivers may encounter. In this case, try to drive in the rut left by the front car, not by the side of the road. If you feel the driving wheel slipping, release the throttle immediately. Increase the distance from the car in front for at least ten seconds. Don't slam on the brakes, it may cause sideslip. If sideslip occurs, release the brakes immediately so that the steering wheel can regain control of the car. Do a good job of braking before entering the corner, and never step on the brakes in the corner. Inertia will make your car out of control. (5) When driving in snowy days, you should increase the distance from the vehicle in front, and then brake in advance. When it is found that the distance from the vehicle in front is shortening, whatever the reason, you should immediately slow down, put your feet on the brake pedal and prepare to brake. Don't take chances and be careless. According to traffic safety experts, the friction coefficient of normal dry asphalt pavement is 0.6, which drops to 0.4 in rainy days and 0.28 in snowy days, and the ice pavement is even lower, only 0. 18. The friction coefficient decreases and the braking distance increases. If the driver is still driving like a normal road in rainy and snowy weather, it is easy to rear-end. Therefore, drivers should increase the distance between cars and extend the braking distance. (6) Don't brake with or without ABS, except when parking. Stepping on the low-speed brake can reduce the speed of the vehicle more quickly with the help of engine deceleration. For a car without ABS, it is easy to lock the tires by pulling the brakes. If the front wheel is locked, the car will lose control of the driving direction and move in the inertial direction. At this time, it is useless to manipulate the steering wheel. If the rear wheel is locked, the car will roll over and the direction will be even more uncontrollable. Of course, even if you hang up the brakes, don't trample the brake pedal to death without an emergency. You should push hard gradually. If the vehicle speed is high or you need to brake as soon as possible, you can directly downshift and brake: for example, if the gear is in the fourth gear, first release your right foot from the accelerator pedal and put it on the brake pedal, and then quickly press the clutch with your left foot to quickly shift to the third gear. In case of emergency, you can directly shift from fourth gear to second gear or even 1 gear, and then lift the clutch. After the clutch is engaged, step on the brake pedal with your right foot, but don't step on it. If you feel that the wheels are locked, release the brakes immediately, and the car with ABS can also directly downshift. The difference is that when the speed is slow, you can step on the clutch (to prevent the engine from turning off) and step on the brake (only when the speed is slow), and let ABS handle the rest.

Precautions for driving in snow and precautions for using brakes in snow! !

No matter what kind of driving model you drive, you need to look at the following precautions, for your own safety and for the safety of others. It should be pointed out that in addition to the basic precautions, friends who drive behind the wheel should pay more attention. For example, rear-wheel drive should try to avoid driving on big slopes. If possible, you can replace special tires or put some items in the trunk to increase the weight of parking spaces and improve the adhesion of rear wheels.

Clear the snow before driving.

After heavy snow, the car body is often covered. At this time, if you drive on the road, it is easy to feel the glistening around you, which makes the driver unable to open his eyes. This is why many people are afraid to drive on the road. For safety, clear the snow on the windshield, headlights and rearview mirror in time before driving. You can do these things when the car is hot in winter, and it won't take too much time, but it greatly improves the safety. In addition, it is best to wear sunglasses to protect your eyes when driving in heavy snow.

Speak steadily on the road.

Driving in the snow, the first point is "slow". There are too many unpredictable factors in driving in snowy days, so driving slowly can give you more time to judge and make correct operations. Drivers who drive manual gears should lift the clutch as slowly as possible when starting on icy roads. The computer of the EFI vehicle will automatically adjust the fuel injection quantity according to the load, and output more torque, so that the power of the engine can be released to the driving wheels smoothly. It is forbidden to lift the clutch with the big foot accelerator, which is not only not conducive to starting, but also easy to cause the vehicle to slip, lose direction control and accidentally hit other vehicles. For automatic transmission vehicles, if the vehicle itself has snow mode, it should be shifted to the snow gear in time; for vehicles without snow mode, it should be shifted to the corresponding "3", "2" or "1" booster gear according to the adhesion degree of the specific road surface to ensure good torque of the vehicle on the snow and ice road surface.

Use the brakes carefully.

When driving in snowy days, you should increase the distance from the car in front. The friction coefficient of normal dry asphalt pavement is 0.6, which decreases to 0.4 in rainy days and 0.28 in snowy days, and the ice pavement is even lower, only 0. 18. The friction coefficient decreases and the braking distance increases. If the driver is still driving like a normal road in rainy and snowy weather, it is easy to rear-end. Therefore, drivers should increase the distance between cars and extend the braking distance.

For manual transmission models, except when parking, as long as the car is moving, try not to brake in neutral, because the speed can be reduced faster with the help of the engine's own deceleration. Don't slip in neutral for automatic transmission models, otherwise it will lead to poor lubrication and premature wear of some parts. For vehicles without ABS, neutral braking is not allowed, because if the control is slightly poor, it is easy to lock the tires. Once the front wheel is locked, it will completely lose control of the driving direction, and the car will drive along the inertial driving direction. At this time, turning the steering wheel will be powerless. If the handbrake is locked by the rear wheel, the vehicle will swing sideways and lose control of the direction. The correct braking method is to step on the brake with a block. Don't step on the brake pedal at once, but push hard step by step. If you step on the brakes at once, the engine is likely to lose power because the wheels are locked and turned off, resulting in the vehicle losing control. If emergency deceleration from high speed is needed, it can be achieved by braking and quick downshift. For example, if the car in front stops suddenly when driving at a speed of 80km/h, you can immediately step on the brake, step on the clutch with your left foot, and quickly shift the gear to the second gear or 1 gear, but this is only for emergencies, because improper operation may damage your car.

If the vehicle skids, keep calm. If it is caused by braking, stop braking immediately. If the vehicle skids to the left, turn the steering wheel to the left, and vice versa, but the movement should not be too big, otherwise it will skid in the opposite direction. You can't use the handbrake, because the handbrake of most vehicles is to brake the rear wheel, which is easy to slip. When driving, in case of turning at a small angle or icing on the road, sudden braking may cause the car to sideslip.

Convenient for others and convenient for yourself.

Pay attention to the "margin" when driving. Leave more for yourself or others when driving, and don't argue. Always keep a safe distance from the vehicle in front, and slow down in advance in case of any situation. When you find that the front car is braking, you should immediately collect the oil and prepare to step on the brake pedal. When braking, look at the distance behind the car. If the rear car is too close, it is best to slow down and brake when there is a large space with the front car. Although the rear-end collision is the responsibility of the rear car, repairing the car is your own time.

It's right to drive more carefully in snowy days, but don't be nervous blindly. In an emergency, mental stress will lose its response because of panic or sluggishness, and it is impossible to deal with the situation quickly. Relax, slow down, pay attention to the front and three rearview mirrors when driving, and pay attention to the vehicles on the left and right, so as to be aware of it. Try not to change lanes frequently. If necessary, turn on the turn signal first, then look at the road conditions through the rearview mirror before changing lanes.

When driving in snowy days, try to avoid sudden steering, sudden start and sudden braking. All actions should be half a beat slower than usual, especially when leaving the main road, turning right, crossing the road and crossing the intersection, pay more attention to pedestrians and bicycles. When climbing a steep slope in ice and snow, pay attention to the distance between the front and rear cars, hang the low gear and keep the throttle steady to climb up, and try not to shift gears halfway. Because the low gear itself has a large torque, the wheel speed is low when driving, and it is not easy to slip, which can effectively avoid being forced to stop on the slope for slope lifting or rolling due to insufficient strength.

Tips:

Make sure there is no snow or thin ice under your feet when driving, because you may slip when you want to brake, and the result can be imagined.

Comrades with glasses should pay attention to driving. When the temperature in the car is very high, don't drive away immediately, because your glasses will fog immediately, which may be an instant thing. When you can't see it, it may bring security risks.

When the vehicle stays overnight, the following points should be paid attention to when there is no garage: 1, lift the rain hanging piece after parking, so that it will not freeze the next day; 2. Make sure all your cars are locked, because cold weather may lead to the failure of a door lock; 3, parking must be far away from other vehicles, because when driving in the morning, if you drive improperly, the vehicle will have a tail flick, maybe it is your car.

When it snows during the day, you must remember to turn on the fog lights and running lights, which is likely to lead to a collision because of the oncoming car or the poor visibility of the car behind you.

When encountering icy or snowy roads, you must not overtake, because it is not good enough, and you may hit the overtaking car and cause an accident.

When driving in snowy days, prepare a piece of cotton cloth at hand, which can wipe the fog and reflector on the inside of the window when parking and keep a good line of sight.

When driving a motor vehicle, try to stay away from the bicycle to prevent skidding accidents.
