What Lights Should Be Turned On in Time When Driving in Foggy Weather?

When driving in foggy weather, it is necessary to turn on the fog lights, hazard warning flashers, and headlights in time. Safety precautions for driving in foggy weather: 1. Correct use of lights: Turn on fog lights in foggy weather as their light waves can penetrate the fog more easily and illuminate farther. When the fog is extremely thick, you can turn on the hazard warning flashers because yellow light has better penetration through fog. Remember not to use high beams, as their light waves will be reflected back by the fog, similar to shining on a vast white wall. 2. Use the horn for alerts when necessary: Since visibility is poor in foggy weather, it is advisable to honk the horn appropriately when overtaking, turning, or encountering pedestrians to provide a driving signal. 3. Reduce speed and avoid sudden braking: First, slow down. Poor visibility in foggy weather means most vehicles are moving slowly, and high speeds can easily lead to rear-end collisions. Additionally, reducing speed can help avoid sudden braking. It is difficult to judge distances in foggy conditions, and sudden braking can easily cause accidents for vehicles behind. 4. Avoid reckless overtaking: Do not rush to overtake in foggy weather, as low visibility makes it harder to assess the situation ahead of the vehicle in front. Therefore, especially in heavy fog, not only should you turn on the hazard warning flashers, but it is also best to maintain a certain distance and follow the vehicle in front. Only when you can confirm the situation ahead should you honk and pass at a low speed.
The key to driving in fog is promptly turning on the fog lights, including both front and rear fog lights. I once encountered a dangerous situation while driving in fog when using high beams actually made it harder to see the road because the reflected light created a white wall effect. Fog lights are designed with a low angle and strong penetration, distributing light evenly to illuminate the road nearby without glare. My habit is to activate the fog lights as soon as I enter a foggy area, along with the position lights to enhance side visibility. I reduce speed to 40-50 km/h and maintain a following distance of at least 50 meters. Regularly checking the car lights is crucial—replace aging bulbs promptly. Don’t forget to use the air conditioning to defog the interior, which prevents blurred vision. Safety comes first, and these steps have ensured my safe return home every time I drive in fog. Developing good habits is essential.
