How to drive safely in foggy weather?

Poor eyesight is the main cause of traffic accidents in foggy days, so the most important thing to pay attention to when driving in foggy days is to control the speed and try not to drive at a speed exceeding 100 km/h. Experts suggest that when the visibility is less than 500 meters and more than 200 meters, the speed should not exceed 80 kilometers per hour; When the visibility is less than 200m and greater than100m, the speed shall not exceed 60km/h; When the visibility is less than 100 meters and more than 50 meters, the speed shall not exceed 40 kilometers per hour; When the visibility is less than 30 meters, the speed should be controlled below 20 kilometers per hour; Generally, when the sight distance is about 10 meter, the speed should be controlled below 5 kilometers per hour.

Turn on all kinds of lights (except high beam) when driving in foggy days, and turn on double flashing lights when driving at high speed or in dense fog. Remember not to use the high beam in foggy days, because the high beam shines upward, and the light emitted is diffusely reflected by the fog, which will form a vast expanse of whiteness in front of the car, but you can't see anything when driving.

Don't overtake blindly. Pay attention to pedestrians on the road. If you find that the vehicle in front is parked on the right, don't overtake blindly, because you are probably waiting for the opposite car to pass. When overtaking a vehicle parked on the side of the road, after confirming that there is no intention to start and there is no car coming from the opposite side, sound the horn at the right time and make a low-speed detour from the left side.

Keep the speed relatively low. When driving in foggy weather, strictly abide by the traffic rules and speed limit, and do not overspeed. The greater the fog, the shorter the sight distance and the lower the vehicle speed. When driving at high speed, the visibility is less than 200 meters. Turn on fog lights, low beam lights, position lights and front and rear position lights, the speed shall not exceed 60km per hour, and keep a distance of more than100m from the vehicle in front of the same lane; When the visibility is less than 100 meters, turn on fog lights, low beam lights, position lights, front and rear position lights and hazard warning flashlights, and the speed shall not exceed 40 kilometers per hour, and keep a distance of more than 50 meters from the vehicle in front of the same lane; When the visibility is less than 50 meters, turn on fog lights, low beam lights, position lights, front and rear position lights and danger warning flashlights, and the speed shall not exceed 20 kilometers per hour, and leave the expressway as soon as possible from the nearest exit.
