Show answer and explanation
Correct answer: The beginning of a tunnel or underpass.
The , showing a tunnel entrance, marks the start of a tunnel or underpass, and the number below it, here 17 km, is its length. You must keep your lights on inside, even during the day, because the rules require this in tunnels, but the sign itself indicates the tunnel.
