The Ministère limits the loads and dimensions of vehicles and vehicle combinations to protect infrastructures and to ensure the safety of the other road users.
The Highway Safety Code allows road vehicles respecting the loads and dimensions authorized by the Vehicle Load and Size Limits Regulation to use the whole Québec road network.
When a road vehicle or a road vehicle combination cannot comply with the rules established by the Regulation, it can be possible to obtain a special permit for circulation.
Since February 11, 2019, all applications for Class 1 to 7 special permits and for special road train operating permits must be addressed to the ministère des Transports.
The GPM system is a fully transactional online tool that allows for optimal management of permit applications, 365 days a year, 24 hours a day. The Ministère also uses this new tool to issue special permits.
For additional information about the regulations and tariffs applicable to special permits, consult the webpages for the categories of permits indicated above (classes 1 to 7 or road trains).
