Stopping in a tunnel is **dangerous** and should be avoided whenever possible. Here we explain why:

- **Reduced visibility:** Tunnels usually have less lighting than open roads, making it difficult for other drivers to see a stopped vehicle in time. This increases the risk of collisions.

- **Limited space:** Tunnels have restricted space, meaning a stopped vehicle can obstruct traffic flow and hinder the passage of emergency vehicles if needed.

- **Emergencies:** If a vehicle must stop due to an emergency, there are specific steps to follow, such as turning off the engine, turning on the hazard lights, and moving the vehicle to an emergency area if possible. Additionally, all occupants should exit the vehicle and head to a nearby shelter or exit.

- **Fire risk:** In case of fire, it is crucial to leave the vehicle and move quickly towards a shelter or exit, always in the opposite direction of the fire.


For these reasons, stopping in a tunnel without a justified cause is dangerous and should be avoided to ensure the safety of all road users.
