It's necessary to inspect your vehicle and your equipment, no matter how efficient and thorough the maintenance policy of a company or vehicle owner may be. Even if your vehicle is one which is required by law to be inspected periodically, and carries a valid inspection certificate and decal, you should inspect it. As a driver, you should know which equipment must be inspected before driving. You should inspect your vehicle periodically during a long trip. You must be able to determine if any equipment or component is showing signs of failure or improper operation.
The investment of a few minutes required to check a vehicle before starting out will often prevent you from having costly delays en route, and reduce the risk of collisions resulting from mechanical failure.
To carry out an efficient and thorough circle check in a short period of time, follow the systematic check procedures explained in the following pages.
It is an offence to drive, or permit another person to drive, your vehicle on a highway if any vehicle part (or parts of its equipment) is defective or inoperative.
Prior to a road test, for a Class 1, 2, 3 or 4 licence you will be required to perform a circle check on the vehicle in which the road test will be taken. You will be asked to name and point out each item being inspected, as described in the following pages, without any assistance and without using a checklist. The circle check described is the minimum type of inspection which is expected prior to a road test. (The school bus circle check is described on School buses - Daily circle check.)
The purpose of completing a circle check test is to assess the driver's knowledge of vehicle safety requirements and to check the proper operation and condition of all equipment.
