Every 6 months – at least – owners must have their heavy vehicles undergo mechanical maintenance to ensure their safety.
In order to monitor the mechanical condition of their heavy vehiclesA road vehicle having a gross vehicle weight rating (GVWR) of 4,500 kg or more, or a combination of road vehicles having a gross combination weight rating of 4,500 kg or more. The following vehicles are also considered to be heavy vehicles regardless of their GVWR: buses, minibuses, tow trucks, vehicles transporting dangerous substances requiring the display of safety marks., owners must set up a mechanical inspection plan and make any corrections required in order to avoid potential mechanical defects. Mandatory maintenance includes all planned interventions intended to maintain a heavy vehicle in good working condition. Owners can do their own servicing or contract the work out to the establishment of their choice. In any case, it remains the owner's responsibility to see that maintenance is done correctly and at the proper intervals.
Vehicle maintenance must be carried out at least once every 6 months.
Important: Mandatory mechanical maintenance is no substitute for the mandatory periodic mechanical inspection.
Buses and minibuses: mechanical maintenance is also mandatory
Since buses and minibuses are considered to be heavy vehicles, their owners must have them undergo mechanical maintenance.
The following information must appear on the maintenance sheet:
We recommend certain maintenance sheet models, which can be used as is or modified to suit your needs, provided that they meet the requirements.
Retention period for maintenance sheets
Maintenance sheets are part of the record of each vehicle. The owner must keep them in the vehicle record for the period covering the last 2 years during which the vehicle was in use and they must be kept for 12 months after disposing of the vehicle.
Every 6 months, owners of heavy vehicles with a GVWR of 7,258 kg or more must measure the brakes of their heavy vehicles and record the measurements in the Registre de mesures de freins et de pneus (PDF, 97 KB) (Brake and Tire Measurement Record – in French only).
Tire measurements are optional.
Recording brake and tire measurements in the Registre de mesures de freins et de pneus, instead of on the maintenance sheet, makes it possible to monitor wear from one inspection to the next and detect any abnormal wear before a breakdown occurs.
The owner must ensure that the necessary repairs listed on the maintenance sheet are made.
Proof that the items found to be non-compliant were repaired must be kept in the vehicle maintenance record.
A vehicle with a major defectA mechanical defect that poses an immediate threat to the safety of road users, including that of the driver. The vehicle may not be driven or put into operation until the defect has been repaired. is prohibited from being driven or operated. The vehicle may not be driven until it is repaired.
Any minor defectA mechanical defect that does not pose an immediate threat to the safety of road users but that may deteriorate rapidly. The defect must be repaired within 48 hours of being detected and entered in the pre-trip inspection report. detected must be repaired within 48 hours otherwise the heavy vehicle may not be operated.
