Section 633 of the Highway Safety Code

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​When the size or load of a vehicle exceeds those permitted under the Vehicle Load ​and Size Limits Regulation, a special permit can be issued on request, as applicable.

In the event that a special permit cannot be issued under the Regulation respecting special permits or the Special Road Train Operating Permits Regulation, the Minister can issue a special permit by virtue of the powers conferred on him under section 633 of the Highway Safety Code (HSC) since 1986.

This type of permit is intended for the transportation industry as a whole. This list of the different types of permits is available in the “General Information” section.

Normative framework

The Minister may issue a special permit when a road vehicle or a combination of road vehicles is non-compliant with the regulation (paragraph 20 of section 621 of the HSC).

To grant the permit, the Minister must consider it justified by exceptional circumstances and consult the Société de l'assurance automobile du Québec (SAAQ). He shall fix the conditions attached to the permit, the fee exigible and the amount and nature of the security.

Target clientele

The operator, owner, distributor and driver of an outsized road vehicle or combination of outsized road vehicles, both heavy and light, must comply with the standards of the permit. However, this permit does not absolve the obligation to comply with any other legislative or regulatory requirement.

General information


Certain permits concern the transportation industry as a whole. A few examples of permits are presented in the table below. They indicate the requirements and limits attached to these permits. Costs, if applicable, include administration fees.

If your rating is conditional, your request will be reviewed within three working days. To know your safety rating, visit the Commission des transports du Québec website (in French only).

Permit renewal and notice of expiry
