BDifficulty 2/5

You are stopped in a prolonged traffic jam inside a tunnel. Besides keeping position lights on, which light signal must you temporarily activate to warn drivers approaching from behind?

Correct answer

The hazard warning lights.

Hazard warning lights. Article 97.3 requires temporarily activating them, keeping position lights on and switching off the engine when stopped by traffic. Do not leave the vehicle merely because of the jam; follow panels and announcements and keep as far back as possible from the vehicle ahead. A breakdown, fire or other emergency can require different actions.
