If your vehicle suffers a **breakdown in a tunnel** and can still move, it is important to continue driving until you exit the tunnel or reach an **emergency reserved area**. This is crucial to avoid obstructing traffic and ensure the safety of all tunnel users.

- **Continue driving**: If the vehicle can still move, even at a reduced speed, you should try to exit the tunnel or reach an emergency area. This helps minimize the risk of accidents and facilitates access to assistance services if necessary.

- **Emergency areas**: These areas are designed for situations like breakdowns, where vehicles can stop without obstructing the flow of traffic. Upon reaching one of these areas, you can safely request help.

- **Safety in the tunnel**: Stopping inside the tunnel unnecessarily can be dangerous due to lack of visibility and limited space. Therefore, it is preferable to continue to a safe place.


In summary, if your vehicle can continue moving, you should do so until you exit the tunnel or reach an emergency area. This ensures your safety and that of other drivers.
