Characteristics of driving skills in rainy and snowy weather

The snowy road is slippery. If there is a thin layer of ice on the road surface, it will form the phenomenon of "ground penetrating armor", which will reduce the friction coefficient between the automobile tire and the road surface and greatly reduce the adhesion, which will bring a lot of trouble to the automobile.

What are the characteristics of traffic accidents in rainy and snowy weather in winter?

As we all know, the road is slippery on snowy days. If there is a thin layer of ice on the road surface, it will form the phenomenon of "nail grinding", which will reduce the friction coefficient between the automobile tire and the road surface and greatly reduce the adhesion, which will bring a lot of trouble to the automobile driving.

Second, when the vehicle is driving on the ice and snow road, the driving wheel of the vehicle is easy to slip or idle, especially when going uphill, starting and parking, the vehicle will slip back. If the vehicle suddenly accelerates or decelerates during driving, it is easy to cause sideslip and direction deviation. During emergency braking, the braking distance will be greatly extended, which is more than 4 times higher than that of ordinary dry roads.

Therefore, when vehicles are driving, they need to keep different safe driving distances in the face of different roads and different climates. Especially when driving on icy roads, the most important thing for new and old drivers is to slow down and collect oil in advance; Lightly step on the brakes, and the engine brakes; Relax the distance, widen and narrow. Specifically, we should pay special attention to the following aspects:

Slow start, slow clutch and slow refueling.

If the wheels slip when starting, you can shift to a higher gear than usual. For example, cars can start in second gear, trucks can start in third gear when they are empty, and heavy trucks can start in second gear. The release of the clutch is slower than usual, so it is best to adjust the transmission force with the range of semi-clutch. As long as the engine is not turned off, the throttle is smaller than usual when starting. Once the wheels turn, shift to low gear immediately, and you can refuel normally. All these require the driver to shift gears quickly, and the coordination of throttle, clutch and gear should be accurate.

Keep low speed and stability while driving.

Because the braking distance will increase with the increase of vehicle speed, it is the key to control the vehicle speed and keep a large safe distance from the vehicle in front. Generally speaking, how high the driving speed is and how long the safe driving distance should be kept, such as 30 kilometers per hour and 30 meters. Because it takes 0.03 seconds for the driver to press the brake pedal at the earliest, the mechanical reaction time needs 8.33 meters. Therefore, if the vehicle runs too fast, the safe distance between the two vehicles will be smaller, and once an emergency occurs, the consequences will be unimaginable.

It is forbidden to drive the steering wheel on the road.

When you need to turn, you should also slow down first, appropriately increase the turning radius, and slowly hit the steering wheel. Hold the steering wheel with both hands and operate it smoothly and gently, otherwise it will slip. This is because the steering wheel is shifted sideways because of the excessive steering, which leads to a sudden increase in the resistance of the front wheel of the vehicle and the tail of the vehicle is thrown out under the action of inertia. Especially in mountainous roads in the suburbs, sometimes the snow and ice roads are intermittent, so it is best to take measures in advance when driving and finish them in intermittent places. If you make a sharp turn on the icy road, it is very likely that a major traffic accident will occur because you slip across the road or rush out of the subgrade. There are different ways to step on the ABS brake.

Vehicles without ABS equipment: When slowing down and stopping on the icy road, you should first use the "resistance" of the engine to slow down quickly one by one, and then press the brake pedal repeatedly and quickly to stop smoothly.

Vehicles equipped with ABS equipment: you can also shift to a low gear and use the "traction" of the engine to slow down in advance, but you must immediately step on the brakes to the end and control the steering wheel. Don't use the method of "braking", otherwise ABS will not work, but it will be dangerous.

In addition, don't drive in the snow with or without ABS. When braking, they will slow down due to snow resistance and engine resistance. On the ice, even if the gear declines, it is far better than sliding in neutral because the driving wheels are stressed at the same time, and the tires are not easy to lock up.

Keep a safe lateral distance.

When entering and leaving the main road, passing through the intersection, turning left and right, passing cars, and meeting pedestrians and bicycles on the icy road, we should give full consideration to others, politely avoid them, and always keep a large lateral safety distance. Under normal circumstances, we should not use flashlights and whistles to rush others, otherwise it will cause others' mental panic. Sometimes, bicycles and pedestrians may accidentally fall down on both sides of non-motor vehicle lanes or hutongs in mixed sections, and drivers would rather stop to make way than grab the lane to avoid personal injury and death accidents that may occur at any time.

Maintain a good mental state.

For experienced old drivers, although the ice and snow pavement is not terrible, it is still necessary to slow down carefully and deal with it according to different situations. The icy road is really a test for new drivers. As the saying goes, "drive gently." Especially when driving on steep grade overpass, it is very difficult to go uphill and downhill, and it is easy to stall. New drivers can take the auxiliary road to avoid the danger of driving up and down the bridge area many times. Be sure to remember that in case of sudden emergency, don't panic and don't do anything drastic. You should calm down and deal with it decisively according to your own analysis and judgment.
