According to applicable size limits standards in Québec, the prescribed maximum length for a road train is 25 meters. However, driving a road train with a length exceeding 25 meters can be authorized based on the conditions set out in the
Special Road Train Operating Permits Regulation.
The framework set out in this regulation aims to ensure road user safety. The road trains targeted by this regulation generally consist of a road tractor hauling two semi-trailers, each of which can be up to 16.2 meters long. This road train configuration is used for the transportation of high volume and low mass loads.
Section 463 of the
Highway Safety Code (Chapter C-24.2) prohibits the driving of outsized vehicles on public roads. However, the section stipulates that a special permit may be issued for certain situations.
Section 621 of the Highway Safety Code stipulates that the government can, by regulation, determine the formalities for obtaining a special permit and the conditions attached to such a permit. By virtue of this authority, the government has adopted the
Special Road Train Operating Permits Regulation to govern the use of road trains over 25 meters in length.
Special Road Train Operating Permits Regulation targets operators and drivers of heavy vehicles, shippers and transportation service intermediaries.
The operation of a road train over 25 meters long is authorized on condition that the operator holds a special permit. The use of such vehicles is limited to divided highways and short road sections along these highways.
The rear of the second semi-trailer must be equipped with a sign, as set out in the Special Road Train Operating Permits Regulation. This sign is a pictogram of a black road train on a fluorescent yellow retro-reflective film. It is not required when the vehicle is configured as follows: tractor, semi-trailer and dolly.
It should be noted that the “train routier” sign meeting the specifications in effect prior to July 17, 2014, can no longer be used as of January 17, 2016.
The total loaded mass limit is 67,500 kg. The axle categories and axle weight limits are determined by the
Vehicle Load and Size Limits Regulation. This is true for height and width limits. This combination of vehicles is therefore outsized only in terms of length and total loaded mass.
The driver must have at least five years’ experience driving a combination of road vehicles and hold a driver’s licence with a “T” endorsement. The maximum speed allowed is 90 km/h.
The special permit is issued for a period of three or nine months. It is forbidden to operate these road trains in the months of December, January and February, as well as on Sundays and on holidays. The operation of these road trains is also subject to other conditions.

The Ministère is extending the demonstration project allowing the operation of road trains over 25 meters long in the winter (December to February). This project allows the operation of this combination of vehicles on the roads covered by the Special Road Train Operating Permits Regulation under certain additional conditions aiming to ensure road user safety.
The main conditions of the project are detailed in the Info-camionnage newsletter of November 1, 2018, available in the “Documentation” section below.
The Gouvernement du Québec has adopted the Regulation Amending the Special Road Train Operating Permits Regulation, which was published in the Gazette officielle du Québec on July 2, 2014. The provisions of the regulation came into effect 15 days after this publication.
The main amendments of the project are detailed in the Info-camionnage newsletter of July 9, 2014, available in the “Documentation” section below.
This guide exposes the main provisions of the
Special Road Train Operating Permits Regulation, along with a few other rules applicable to these combinations of vehicles.
