What are the precautions for safe driving on snowy roads in bad weather in winter?

★ Preheating: Preheating is the first and especially important step of driving in winter. XX is here to give you a common preheating method. Because of the low temperature in winter, the viscosity of lubricating oil is much higher than that in other seasons, and it is not easy to flow. Therefore, after starting the engine, the engine should be kept at about 1000 rpm, and the car should be warmed up before starting. Don't slam on the accelerator at this time, and the engine speed should not be too high. Preheating does not need to wait for the engine temperature to rise to the optimal temperature before starting, as long as the thermometer pointer starts to rise.

★ Starting: Starting in winter must be relatively gentle and slow, which is beneficial: on the one hand, the load of the engine is as small as possible when it does not reach the normal working temperature, on the other hand, the tire has a buffer process of gradually heating up from the initial stiff state, so that the tire will not slip in the initial stage. Therefore, this starting method is good for the engine, tires and safety.

★ Shift: I believe that old drivers will have their own set of driving habits and methods. In short, they need to change gears more frequently in winter, just like driving during the running-in period, and pay more attention to the selection of gears and the coordination of oil distribution. Too low or too high a gear is easy to make the car out of control, which is especially important when driving on ice and snow roads. If it is an automatic car, be careful not to slam on the brakes. You should make a good prediction to avoid an emergency. You can't brake in time.

★ Route selection: Route selection is directly related to the driver's safety and the overall smooth driving, whether driving on ice and snow roads or normal roads. Try to stay in a straight line and don't change lanes frequently. It is best to walk along the rut where there is rut. If there is no rut, you should pay attention to the surrounding reference objects, identify the direction of the road, beware of snow-covered potholes and ice under the snow, and try to drive in the middle of the road if possible, because the left and right sides can be regarded as buffer zones, and even if there is an emergency, they will not rush directly under the road.

★ Meeting: Generally speaking, meeting on the road in winter is the same as in other seasons, but you can't be careless, because the temperature inside the car will be higher, and drivers are more likely to feel sleepy than in other seasons. The most important thing is to slow down as soon as possible in the case of snow and ice, especially in the case of urban and rural roads and general road conditions, try to meet in straight roads and slightly wider sections, and try to avoid meeting in corners.

★ Overtaking: In winter, because the leaves fall off, the view will be slightly better than other seasons, but at the same time, due to the open space and strong wind, it is difficult for the front car to hear the horn of the rear car. Therefore, when overtaking, speakers and headlights should be used reasonably, and overtaking should be done when the front car makes a move and there is enough space. In particular, it is very dangerous to overtake in snowy days. When overtaking is really necessary, you should choose a wide and straight section with enough safety distance on the opposite side to overtake. Don't change lanes immediately after overtaking, but try to leave a safe distance for being overtaken.
