Do the same rules apply to tunnels and underpasses?
Right of way
Explanation
The **traffic regulations** for **tunnels** and **underpasses** are the same, which means they apply uniformly in both cases. Here we explain why:
- **Entry and circulation:** Entry into a tunnel is not allowed if there is a traffic light prohibiting passage. Additionally, inside the tunnel, a **minimum distance** of 100 meters (or 4 seconds) must be maintained with the vehicle in front. For heavier vehicles, this distance increases to 150 meters (or 6 seconds).
- **Emergencies:** In case of an emergency inside a tunnel, specific steps must be followed such as turning off the engine, turning on the position and emergency lights, and moving the vehicle to an emergency area if possible. All passengers must exit the vehicle and head to the nearest shelter.
- **Fires:** If there is a fire, the vehicle should be moved to the right to allow emergency vehicles to pass, the engine should be turned off, and the doors left open. Passengers must evacuate in the opposite direction of the fire.
- **Traffic stops:** If traffic stops inside a tunnel, the driver must turn off the engine and turn on the position lights. Passengers should remain inside the vehicle.
These regulations ensure **safety** and **order** in both tunnels and underpasses, applying identically in both.
