How to Use Front and Rear Fog Lights Correctly?
2 Answers
Fog lights are generally used as emergency lighting tools under severe weather conditions and should not be used as daily lighting. Basic introduction to fog lights: 1. Usage scenarios: Article 81 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" clearly states that when visibility is less than 200 meters in rainy or foggy weather, motor vehicles should turn on fog lights. 2. Precautions for use: Fog lights can become very dazzling in good visibility conditions. The glaring light from fog lights can interfere with or even harm the eyes of other drivers, potentially leading to accidents. Therefore, traffic regulations in many countries explicitly prohibit the use of fog lights when visibility is good.
When it comes to the correct use of front and rear fog lights, my driving instructor emphasized this repeatedly when I was learning to drive—it's especially important! Front fog lights are primarily used in low visibility conditions such as fog, rain, or snow to illuminate the road ahead, helping the driver see more clearly. The switch is usually located on the dashboard with a fog light icon button—don’t confuse it with regular headlights. Rear fog lights, on the other hand, make your vehicle more visible to drivers behind you in such conditions, preventing rear-end collisions. However, they are extremely bright, and if left on in clear weather, they can dazzle other drivers and may even result in a fine. Only turn them on when visibility drops below 100 meters, such as in heavy fog, torrential rain, or dusty mountain roads. Remember to turn them off immediately after use to avoid draining the battery or shortening its lifespan. New drivers often forget the switch location, so it’s advisable to check the vehicle manual first to familiarize yourself with the controls. Develop the habit of turning them on only when needed and off afterward—safety comes first!
