You're driving through a congested tunnel. What should you do if you have to stop?
- A Stop very close to the vehicle in front to save space
- B Ignore any message signs as they're never up to date
- C Keep a safe distance from the vehicle in front
- D Put your headlights on full beam
Why this is the answer
It's important to keep a safe distance from the vehicle in front at all times. This still applies in congested tunnels, even if you're moving very slowly or have stopped. If the vehicle in front breaks down, you may need room to manoeuvre past it.
Why the other answers don't fit
- A
- Stop very close to the vehicle in front to save space — Closing up leaves you no room to get out if the vehicle in front catches fire.
- B
- Ignore any message signs as they're never up to date — Tunnel message signs are live and are the only information you have in there.
- D
- Put your headlights on full beam — Full beam in an enclosed tunnel dazzles everyone around you.
