What must you do in case of a traffic jam in a tunnel?

In case of a traffic jam in a tunnel, it is crucial to follow specific safety measures to ensure the safety of all road users. The correct actions are to switch on the hazard warning lights and maintain a safety distance of approximately 5 meters to the car ahead.

Switching on the hazard warning lights alerts other drivers that you are part of a traffic jam, which is especially important in a tunnel where visibility may be limited. Maintaining a safety distance helps prevent collisions in case the vehicle ahead suddenly moves or if a driver behind you does not react in time.

The choice to secure and leave the vehicle is not recommended unless there is a serious emergency (like a fire) because leaving the vehicle can increase the risk of accidents and complicate rescue operations in such confined spaces. It is essential to remain in the vehicle unless instructed otherwise by authorities. Understanding these rules helps ensure the safety of all individuals in a potentially dangerous situation.
