In foggy weather with a car in front of you, the appropriate lights to use are:
- Low-beam headlights: These provide adequate illumination without causing glare that reflects back from the fog.
- Front fog lights (if your vehicle has them): These emit a wide, flat beam aimed low to reduce reflection and improve visibility of the road directly ahead.
- Rear fog lights (if visibility is very poor): These help make your vehicle more visible to vehicles behind you.
You should avoid using high-beam headlights in foggy conditions as they reflect off fog particles and create glare that can reduce visibility for you and other drivers.
In summary, use low beams together with fog lights (front and rear) if available, and avoid high beams to drive safely in fog when there is a car ahead.
