If, due to an emergency, a driver becomes immobilised inside a tunnel or underpass, they must:
If the breakdown allows you to continue, you must exit the tunnel or underpass; if that is not possible, steer the vehicle towards the nearest emergency area (lay-by); otherwise, immobilise the vehicle on the right-hand edge. You must also:
- Switch off the engine, keep the position lights on and activate the hazard warning signal.
- Place the hazard pre-warning device — a self-coloured yellow device with geolocation and autonomous power supply (battery or accumulator) — positioned as high as possible on the immobilised vehicle to ensure maximum visibility.
- Request assistance without delay via the nearest emergency post (SOS post), if one exists, and follow the instructions received through it.
- Both the driver and all other occupants must leave the vehicle, making their way quickly to the nearest refuge or exit, and must not walk along the carriageway if there are areas excluded from vehicle traffic.
