Question 6519

If traffic is congested and your vehicle comes to a stop inside a tunnel, keep in mind that you must...

  1. turn off the engine if Detention lasts more than two minutes.
  2. turn off all the vehicle's lights to reduce consumption.
  3. turn off the engine and switch from the position lights to the hazard lights.
Show answer and explanation

Correct answer: turn off the engine if Detention lasts more than two minutes.

In a traffic jam inside a tunnel, keep the position lights on the whole time. Once the wait lasts more than two minutes, turn off the engine until you can move again. Turn on the hazard lights briefly to warn drivers approaching from behind, in addition to the position lights, rather than instead of them.
