What lights should be turned on when driving a motor vehicle in foggy weather?

[Weston]

When driving a motor vehicle in foggy weather, turn on the fog lights. If visibility is low, also turn on the hazard warning lights. Here are some precautions for driving in foggy conditions: Use lights correctly. Fog lights should be turned on in foggy weather as their light waves penetrate fog more effectively and illuminate farther. When visibility is extremely poor, you can turn on the hazard warning lights because yellow light has better penetration through fog. Remember not to use high beams. Use the horn for alerts when necessary. In foggy conditions, it's harder to see each other, so honk appropriately when overtaking, turning, or encountering pedestrians to signal your movements. Reduce speed and avoid sudden braking. First, slow down. Foggy weather reduces visibility, and most vehicles move slowly. Driving too fast increases the risk of rear-end collisions. Slowing down also helps avoid sudden braking, which can be dangerous since judging distances is difficult in fog, and sudden stops may cause accidents for vehicles behind. Avoid reckless overtaking. Do not rush to overtake in foggy weather, as low visibility makes it hard to assess the situation ahead of the vehicle in front. Especially in heavy fog, not only should you turn on the hazard warning lights, but it's also best to maintain a safe distance and follow the vehicle ahead. Only when you can confirm the road conditions ahead should you honk and pass slowly at a low speed.
