You are driving in a tunnel and approach the end of a traffic jam. What do you do?

In a tunnel, if you approach the end of a traffic jam, you should switch on the hazard warning lights. This signals to other drivers that there is a hazard ahead and helps improve safety by making your vehicle more visible in the confined space of the tunnel.

Making a U-turn or leaving the vehicle is not allowed or safe in tunnels because tunnels are narrow, enclosed spaces with limited escape options. Stopping the engine and leaving the vehicle could put you at risk due to poor ventilation and potential hazards inside the tunnel. Always stay inside your vehicle, keep hazard lights on, and wait patiently until the traffic clears.
