Which lights should you switch on when daytime visibility is poor but not seriously reduced?
- A Headlights and fog lights
- B Front fog lights
- C Dipped headlights
- D Rear fog lights
Why this is the answer
Only use your fog lights when visibility is seriously reduced. Use dipped headlights in poor conditions because this helps other road users to see you without the risk of causing dazzle.
Why the other answers don't fit
- A
- Headlights and fog lights — Fog lights are only for visibility that is seriously reduced.
- B
- Front fog lights — The same again, and on their own they leave you poorly lit.
- D
- Rear fog lights — Reserved for visibility below 100 metres, and they dazzle the drivers behind.
