Which Lights to Use When Driving in Fog?

When driving in fog, turn on the fog lights, position lights, and low beams. In heavy fog with visibility below 50 meters, additionally activate the hazard warning lights. Below are precautions for driving in foggy conditions: 1. Turn on fog lights promptly. Depending on the situation, use fog lights, low beams, position lights, front and rear position lights, and hazard warning lights to improve visibility. Importantly, avoid using high beams as they reflect off the fog, creating a blinding glare that reduces visibility. If you cannot continue driving on the highway, pull over to the emergency lane, turn on the hazard warning lights to prevent rear-end collisions. 2. Control speed and maintain distance. Drive at low speed according to visibility, keeping a safe distance from other vehicles and pedestrians. Use the horn when necessary to alert others. Avoid overtaking in fog. If a vehicle ahead is stopped on the right, do not blindly pass; consider if it is yielding to oncoming traffic. When passing parked vehicles, confirm they are not about to move and there is no oncoming traffic before honking and passing slowly from the left. 3. Extremely low visibility. If driving becomes impossible on the highway, stop in the emergency lane, activate hazard warning lights, and set up warning signs as required. Quickly move all passengers to the safety of the right shoulder to avoid the danger of being rear-ended while remaining in the vehicle or on the main road.

When driving in foggy conditions, I turn on the low beam headlights and fog lights. The fog lights include front fog lights and rear fog lights. The front fog lights illuminate the road surface near the front of the car, while the red light of the rear fog lights allows vehicles behind to see me and avoid rear-end collisions. Never turn on the high beam headlights, as the water droplets in the fog will reflect the light, blurring visibility instead. If the fog is particularly thick, I reduce my speed to 30-40 kilometers per hour and turn on the defogging function inside the car to prevent the windshield from fogging up. It's a good habit to test all the lights before driving. Once, I forgot to turn on the fog lights in heavy fog and almost hit a road sign. Since then, I always check them. Safe driving is the most important thing. Visibility is too low in foggy weather, and accidents are more likely to happen without lights. It's also essential to maintain the lighting system regularly.

As a frequent driver, I always use low beams combined with front and rear fog lights in foggy conditions. Low beams ensure forward visibility without glare, while fog lights are designed with low brightness to penetrate the fog, and the bright red marker of the rear fog light maintains a safe distance from vehicles behind. High beams are a big no-no, as they cause light to reflect back like a white wall, worsening visibility. Speed control is crucial—I usually slow down and rely on navigation for road condition alerts. Don’t overlook in-car settings, such as the defroster switch, to keep the windshield clear. Avoid using hazard lights unless in an emergency stop, as they can interfere with turn signals. Experience tells me that proper lighting combined with cautious driving significantly reduces risks. Checking for aging lights is also a way to prevent malfunctions in foggy weather.

In foggy conditions, I prioritize using low beam headlights along with front and rear fog lights. The principle is simple: fog consists of water droplets, and the low-positioned beams from low beams and fog lights won't create reflective glare. The red rear fog light can penetrate the fog layer, alerting vehicles behind. High beams must never be used as they scatter severely, making the road invisible. If the vehicle lacks fog lights, low beams alone suffice. Reduce speed by half, and activate front and rear window defoggers. Ensure lights are clean and dust-free with regular simple wiping. This driving approach is safe and reliable, minimizing accidents.
