Their compliance with tunnel transit conditions is certified by a pass, issued after the dimensions of the vehicle, the nature of its load, and the European pollution category have been checked: transit is prohibited :
- for vehicles that have an overall MAM exceeding 3.5 tons classified Euro 0, Euro 1 and Euro 2 (i.e. vehicles registered before October 1st, 2001),

Checking the nature of the goods being carried (dangerous materials are prohibited) is the responsibility of the Highway Police (on the Italian side) and the customs service (on the French side).

The thermographic gateways

At the tunnel entrance aprons, getting heavy vehicles to pass under the experimental thermographic gateway allows tunnel staff to detect any overheating of the mechanical parts of lorries and buses. If the system indicates the presence of abnormalities, the vehicle is made to wait at the tunnel entrance apron for the necessary checks to be made before obtaining transit permission for the tunnel.

Oversized loads

The transit of vehicles which, in accordance with the Mont-Blanc Tunnel transit regulation, belong to category B, is subject to a request for authorisation to be provided in advance to TMB-GEIE (at least 4 days before the date on which the oversized load is due to transit). 
A request can be made by using the form here below (section "Annexes").
