A vehicle is said to be outsized when its load or one of its dimensions exceeds the limits set out in the Vehicle Load and Size Limits Regulation.
The Highway Safety Code (section 463) stipulates that no owner or operator of an outsized vehicle may drive that vehicle on the road network without a special permit issued for this purpose.
Most outsized and overloaded transportation is governed by a permit issuing system and traffic rules.
Outsized and overloaded transportation is evaluated separately before the Ministère makes the recommendation to the Société de l’assurance automobile du Québec (SAAQ) to issue the special permit. Driving conditions are then prescribed based on the particularities of each type of transportation. In both cases, the special permit is issued in compliance with the Regulation respecting special permits.
The Regulation respecting special permits establishes the special driving conditions to be respected when a vehicle is outsized due to its manufacturing and indivisible load.
The Government may, by regulation, in accordance with section 621, paragraphs 19, 20 and 35 of the Highway Safety Code:
This measure applies to outsized road vehicles and combinations of outsized road vehicles that are not targeted by a road train permit or a permit from the minister, issued under section 633 of the Highway Safety Code.
There are seven classes and two categories of special permits.
Each class covers vehicles that meet specific size and load characteristics. Limits are specified for each class. Special conditions are prescribed according to permit category to ensure the safety of transportation movements and protect infrastructures.
The list of conditions is set out by regulation and, depending on the circumstances, one or several of these conditions may apply. They cover road signs, travel hours and itineraries, the presence of police escorts, and so on.
For a complete description of the classes, consult the website of the Société d’assurance automobile du Québec (SAAQ).
The general category authorizes its holder to make trips with or without a specified route for no more than 1 year.
The specific category authorizes its holder to make a trip with a specified route, including the return trip along the same route, for no longer than 7 consecutive days.
For a travel permit and the permit categories, applicants should contact an SAAQ point of service mandated for this type of permit:
