In Pennsylvania, 66 cars were rear-ended in a series of snowstorms. How to realize driving safety in bad weather?

First, keep the air circulating in the car.

There are many suspended particles in the air in foggy days, which are easy to aggregate and solidify into coarse particles when entering the car, which will hinder the air exchange in the engine and cause great damage to the air conditioning system. Suspended particles will attach to air conditioning pipes and filter elements, which is easy to breed bacteria.

Therefore, replacing air and air conditioning filter elements regularly is the first step to avoid the harm of smog. Under normal circumstances, the service life of the original air-conditioning filter element is 1 year or 30,000 kilometers, but the replacement cycle should be shortened appropriately in harsh use environment. In case of fog, the internal circulation mode should be turned on, so that the airflow can circulate in the car to prevent external dust and harmful gases from entering the car.

Second, try to avoid the inner lane.

After a strong wind, the northern region also quickly entered winter. Strong winds can blow away smog, but driving in windy days also requires special attention to safety.

Reducing the speed is also one of the safety measures for driving in windy days. During driving, always hold the steering wheel tightly to prevent the driving route from deviating due to wind, at the same time, try to reduce overtaking, avoid some ultra-high and ultra-wide transport vehicles, and prevent overturning or falling behind.

In the use of lighting, windy weather is often accompanied by dust. In the case of low visibility, turn on the small light in front during the day, use the horn to prompt when necessary, and avoid using the high beam when driving at night.

Third, don't rely too much on high-tech braking systems.

In the northern cities, snowfall in winter will bring great safety hazards to driving, while in the southern cities, road icing after rainfall also makes driving very difficult.

The data show that the friction coefficient between tire and road surface is very small on frozen and snowy roads, only 0,0 1 on icy roads and only 0,2 on snowy roads, so the braking distance is much larger than that on dry roads. Taking the speed of 50 km/h as an example, the braking distance on the dry road surface is 12 m, while the braking distance on the snowy road surface is nearly 50 m, which is quite different.

Therefore, when driving in rain and snow, you must keep enough distance from the car in front and brake in advance. At this time, don't rely on high-tech braking systems such as ABS and EBD, they just play the role of auxiliary braking. The key is to concentrate on predicting the possible situation and brake in time. At the same time, it is also necessary to avoid sudden refueling or sudden braking during driving, so as to avoid vehicle skidding.

When driving on roads with deep snow, you should follow the rut of the preceding vehicle, because the preceding vehicle has compacted the soft snow to prevent it from falling into Zita Law. At the same time, the visibility is poor and the light is not good when it snows. We should use width lights, fog lights and low beam lights correctly.

Extended data

It is particularly important to note that when driving in windy days, you should try to avoid driving in the inner lane, stay away from the middle buffer green belt, and drive in the middle lane as much as possible to prevent the boundary markers in the middle buffer isolation belt from being blown down and causing accidents in windy days.

In addition, it should be noted that when traveling in windy weather, it is necessary to check the tightness of the vehicle before starting the vehicle, such as window tape, to prevent dust from entering the vehicle and affecting safety. At the same time, when parking, avoid parking near buildings and billboards. Prevent the danger caused by falling objects.
