Safety regulations

Keep listening to the radio

20 FM frequencies can be received in the Tunnel. Recorded messages about the rules to be observed during transit are broadcast in 3 languages (Italian, French and English) every 6 minutes; if there is an incident, these frequencies are used by traffic surveillance operators to broadcast directly to your FM radio messages about what you should do.

Observe the no-overtaking rule

The Mont-Blanc Tunnel is a mono tube tunnel with traffic travelling in both directions. Overtaking is strictly forbidden.

Observe the speed limits

- Minimum 50 km/h
- Maximum 70 km/h

Speed detection systems and the system of penalties for exceeding the maximum speed limit are installed in the Tunnel. The information provided by these systems is handled directly by the Binational Police Service at the two aprons.

Keep your distance

The compulsory distance between vehicles is 150 meters: two blue lights located every 150 meters must separate your vehicle from the one preceding yours.

If traffic is stopped in the Tunnel, the 150-metre compulsory distance allows the safety distance of at least 100 metres from the preceding vehicle to be observed (as indicated in the Mont-Blanc Tunnel Traffic Regulation).

Standards of behaviour during an incident

If case of stop of the vehicle preceding yours

- Observe the minimum distance of 100m when at a standstill.

In case of emergency (breakdown, accident, etc.)

- Switch off the engine and turn on your emergency lights.

- If possible, tell the control room using the SOS booths located every 100m.

The tunnel is equipped with SOS booths, placed every 100m alternately in both directions. Every SOS booth is equipped with one emergency telephone and 2 fire extinguishers with usage detector.

The Mont-Blanc Tunnel is equipped with 37 safe shelters (numbered from 0 to 36) located every 300 m on the Italy-France abutments. The safe shelters are connected to the evacuation route in a safe position under the road. This allows users either to move from one safe shelter to another or to leave the Tunnel, and the emergency services to enter the Tunnel on foot. The evacuation route is illuminated and equipped with stations that are connected by telephone to the Control and Command Posts (CCP) every 300 m. Each safe shelter is provided with a video-phone connection with operators at the control post and a public address system for broadcasting messages.

- Help anyone finding themselves in a difficult situation.
- If possible, tell the control room using the SOS booths located every 100m.
- If possible, use the extinguishers inside the SOS booths located every 100m (free of charge).
- Once inside the shelter, you are safe, and the control room is aware that you are there; follow our instructions carefully and read the information boards; in case of emergency a videophone will allow you to contact an operator directly.
