You’re going through a congested tunnel and have to stop. What should you do?

A: Pull up 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: Make a U-turn and find another route

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.
