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

In a situation where you encounter the end of a traffic jam in a tunnel, it's crucial to prioritize safety for yourself and other road users. In Germany, driving in tunnels has specific regulations due to the enclosed environment where hazards can escalate quickly.

The combination of switching on the hazard warning lights is essential. This action alerts other drivers behind you that there is a stationary vehicle ahead, which helps prevent rear-end collisions. It is a standard practice in traffic jams and enhances safety.

However, the answers provided also suggest making a U-turn and leaving the tunnel or switching off the engine and exiting the vehicle. Making a U-turn is prohibited while driving in a tunnel unless in an emergency, as it can cause confusion and create hazards. Likewise, switching off the engine and leaving the vehicle is generally not advisable unless instructed by emergency services or in a dangerous situation, as it can disrupt traffic flow and pose safety risks.

To sum up, the correct approach when approaching a traffic jam in a tunnel is to activate the hazard lights to ensure visibility and safety while maintaining operational control of the vehicle.
