Which lights should you use when you're driving in a tunnel?
- A Sidelights
- B Front spotlights
- C Dipped headlights
- D Rear fog lights
Why this is the answer
Before entering a tunnel, you should switch on your dipped headlights, as this will allow you to see and be seen. In many tunnels, it's a legal requirement. Do not wear sunglasses while you're driving in a tunnel.
Why the other answers don't fit
- A
- Sidelights — Too weak to let you see, or to be properly seen.
- B
- Front spotlights — Those dazzle badly in an enclosed space.
- D
- Rear fog lights — For visibility below 100 metres, and they dazzle the drivers behind you.
