What should you check before you start a journey in foggy weather?
- A The radiator has enough anti-freeze
- B You have a warning triangle in the vehicle
- C The windows and lights are clean and clear
- D You have a mobile phone with you
Why this is the answer
If you have to drive in fog, switch your dipped headlights on and keep all your windows clear. You should always be able to pull up within the distance you can see ahead.
Why the other answers don't fit
- A
- The radiator has enough anti-freeze — Worth checking in winter, but it is not what makes fog dangerous.
- B
- You have a warning triangle in the vehicle — Useful in a breakdown — and never to be used on a motorway.
- D
- You have a mobile phone with you — Handy to have, but it does nothing for what you can see.

Where this question comes from
The question, its options and the explanation are reproduced word for word from the DVSA revision question bank under licence.
