Drivers’ responsibilities

Lists of defects

Operators’ responsibilities

Owners’ responsibilities

Before getting behind the wheel, drivers must make sure that a circle check of their vehicle was completed within the previous 24 hours.

This measure came into effect on November 20, 2016.

In brief

The circle check is a sight and sound inspection of the accessible components of a vehicle that makes it possible to:

  • detect defects as early as possible
  • quickly notify the owner and operator of any defects detected
  • prevent the vehicle from being operated when its condition poses a risk of an accident or a breakdown 


Drivers must carry out these inspections safely.
