What do you do in case of a breakdown in a tunnel?

In the event of a breakdown in a tunnel, the correct actions are crucial for ensuring safety. First, switching on the hazard warning lights alerts other drivers to your situation, which is an essential part of German traffic regulations that focus on road safety. Second, if possible, parking your vehicle in an emergency bay is also critical. This minimizes the risk of obstruction and potential accidents, as traffic can become congested in tunnels.

Running the engine as a precaution, while it may seem logical to some, is not advisable in this scenario. It can create additional hazards, including exhaust fumes accumulating in a confined space, which can be dangerous for you and other drivers.

Therefore, both switching on hazard lights and parking in an emergency bay are necessary measures as outlined by German traffic laws to maintain safety in potentially hazardous environments like tunnels.
