What lights should I turn on when driving in foggy weather?

When driving in foggy weather, fog lights, hazard warning flashers and headlights should be turned on in time.

The following are the safety precautions for driving in foggy weather:

1. Turn on the fog lights in the fog. The light waves of the fog lights can more easily penetrate the fog and illuminate farther. When the fog is very heavy, you can turn on the double flashing warning light, because the yellow light has stronger penetration into the fog. Remember not to use high beam. The light waves from the high beam will be reflected by the fog, just like shining on a wall of white light.

2. Use the horn to remind you when necessary. Because it is difficult to see each other clearly in foggy weather, when overtaking, turning, or meeting pedestrians, you should honk the horn to remind you and give a driving signal.

3. Reduce vehicle speed to avoid sudden braking. First, slow down. Vision is poor in foggy weather and most vehicles drive slowly. If the vehicle speed is too fast, a rear-end collision may easily occur. At the same time, slowing down can also avoid sudden braking. It is difficult to tell the distance between vehicles in foggy weather, and sudden braking can easily lead to rear-end collisions.

4. Don’t overtake blindly. Don't rush to overtake in foggy weather, because visibility is low in foggy weather and it is difficult to spot the car in front. Especially in foggy weather, it is not only necessary to turn on the double flashing warning lights, but also to maintain a certain distance between vehicles. When you can confirm the situation of the vehicle in front, honk again and go around at a low speed.

According to Article 58 of the "Regulations on the Implementation of the Road Traffic Safety Law of the People's Republic of China", motor vehicles shall not drive when there are no street lights, poor lighting, or when encountering fog, rain, snow, sand, dust, etc. When driving at night under low visibility conditions such as hail, headlights, position lights and rear position lights should be turned on. However, when a vehicle behind you traveling in the same direction is driving close to the vehicle in front, you are prohibited from using high beam lights. When a motor vehicle is driving in foggy weather, fog lights and hazard warning flashers should be turned on.
