What lights should motor vehicles turn on when driving in foggy weather?

Motor vehicles should turn on headlights, clearance lights, and rear position lights when driving in foggy weather. When driving close to the vehicle in front in the same direction, high beams should not be used. Fog lights are lighting signals used in rainy or foggy weather, with the main characteristic of strong penetration in fog, making it easier for vehicles or pedestrians to notice early in low visibility conditions, thereby effectively preventing accidents. However, it should be noted that fog lights cannot be used as daily lighting. When visibility is less than 200 meters in rainy or foggy weather, motor vehicles should turn on fog lights. It is important to note that fog lights can become quite glaring in good visibility conditions, which may disturb or even harm the eyes of other drivers.
I've been driving for over a decade and encountered too many foggy days. Experience tells me never forget to turn on your fog lights. Fog lights are usually separate front and rear units - front fog lights help you penetrate thick fog to see ahead, while rear fog lights make your position clear to drivers behind to avoid rear-end collisions. Never use high beams - that light reflects off fog creating a blinding whiteout where you can't see anything, which is extremely dangerous. Remember to reduce speed, maintain safe following distance, and turn on windshield wipers too. Some beginners make the big mistake of only using low beams without fog lights. During annual vehicle maintenance, always check your fog light bulbs - it would be terrible if they failed during fog. Safety first - with proper lighting, driving in fog isn't too difficult.
When I first started learning to drive, my instructor repeatedly emphasized the importance of turning on fog lights in foggy conditions. He explained that front fog lights are used to illuminate the road ahead, while rear fog lights signal vehicles behind not to follow too closely, and warned against using high beams as they create a blinding whiteout that makes it hard to see anything. Later, I tried it myself and found that using fog lights indeed provides much better visibility. In heavy fog, driving slower and turning on the width markers to outline the vehicle can significantly reduce accidents. Nowadays, I notice many cars on the road only use hazard lights or low beams, which is incorrect—hazard lights in fog can mislead others into thinking your car is stationary. Drivers should develop the habit of immediately switching on fog lights when fog appears; it’s a simple operation. With low visibility in foggy conditions, using the correct lights is key to safe driving.
I often drive in foggy weather, and the most important thing to remember is to turn on the fog lights. Fog lights have strong beams that can penetrate the fog, helping you see the road and making you visible to others. Both front and rear fog lights should be turned on—avoid using regular headlights because fog scatters the light, causing glare and reduced visibility. For safety, using the correct lights can prevent accidents, and you should also slow down. If you only use low beams in the fog, others might not clearly recognize your vehicle's outline, increasing the risk of a rear-end collision. Remember, car lights are designed for all weather conditions, and fog lights are a special feature—don’t waste them. Simply put, turning on fog lights is a basic operation—just press a button.
