What are the precautions for driving in bad weather?

In winter, it is frosty, foggy, rainy and snowy, with low temperature and complicated environment. Drivers should improve their understanding of safe driving in winter, strengthen their study of driving knowledge and skills in winter, prevent frost, skidding and accidents, master the handling methods of common problems in winter driving, and ensure driving safety. Keep enough safe distance when driving in rainy days. Pay attention to pedestrians and cyclists in the rain. Because pedestrians wear rain hats, their eyesight and hearing are limited to prevent sudden turning or slipping. In case of heavy rain or rainstorm, don't drive at risk when the wiper function can't meet the visibility requirements. You should choose a safe place to park and turn on the width indicator, and then continue driving when the rain is light or stops. When following, overtaking or passing in the rain, appropriately increase the safe distance from vehicles and road edges. When driving in rainy weather or rainstorm for a long time, it is necessary to prevent the subgrade from loosening and collapsing, and try to choose a solid pavement in the middle of the road. When you encounter a stagnant road surface while driving, you must first observe it. First, observe the water depth, and it is not appropriate to continue driving if it overflows the axle. Before entering the flooded area, pay attention to keep a large distance from the vehicles in front. For unfamiliar roads, drive along the route of the preceding car and avoid obstacles in the water. When entering the water, use a low gear, supply oil smoothly, and move at a constant speed and slowly. Don't stop in the water. Vehicles are not allowed to drive at high speed immediately after driving out of the flooded road. When driving, you should step on the brakes several times, stop and go, and brake by friction in foggy days. When driving, you should pay special attention to the following points. The car is dry, and it can only run normally after confirming that the brakes are effective. Driving in foggy days, make full use of all kinds of lights to improve visibility. Before driving, the windshield, headlights and taillights should be wiped clean, and the lighting device should be checked for completeness. When driving in foggy weather, the vehicle lighting device should not be incomplete. When driving, turn on fog lights, tail lights, width lights and headlights (low beam). When driving in fog, you can rely on the white lane markings on the road and the red taillights in front to guide your sight. In addition, when the visibility of the expressway is less than 100 meters and more than 50 meters, fog lights, low beam lights, width-indicating lights and taillights must be turned on, and the speed should not exceed 40 kilometers per hour; Must keep a distance of more than 50 meters from the car in front of the same lane. In addition, when the visibility is less than 50 meters, the public security organs can take traffic control measures to partially or completely close the expressway in accordance with regulations. At this time, motorists who have entered the expressway must turn on the fog lights, low beam lights, width lights and tail lights according to regulations, and leave the foggy area or drive into the nearby service area to rest under the principle of ensuring safety, and then drive after the fog clears. Motor vehicles that are not equipped with fog lights according to national standards must drive into the emergency parking zone or the nearest shoulder, pull over as far as possible, turn on the danger warning lights according to regulations, and set up warning signs for faulty vehicles at the rear150m. The most important thing on icy roads is caution. When a motor vehicle is driving on an icy road, due to the small adhesion of the icy road, the wheels are prone to slip, sideslip, idle, out of control and increase the braking distance, which is prone to traffic accidents. When driving in snowy days, first, you should be slow, and second, you should keep enough distance from the car in front. Pay attention to the front and three rearview mirrors when driving, and pay attention to the vehicles on the left and right. Then brake early. If the vehicle speed is high or you need to brake as soon as possible, you can directly downshift and brake.
