If you want to drive a truck in Ontario, you need a commercial truck driver’s licence (an AZ driver’s licence). With an AZ licence in Ontario, you can work for a trucking company as an employee, or work for yourself as an owner-operator. The AZ license has two portions – A and Z. The A portion allows you to haul cargo of any size unrestricted. Drivers with a Z-endorsement can operate vehicles that are equipped with air brakes. Many people choose to complete the commercial licence and the Z endorsement (for air brakes) steps together. As a driver of one of the largest vehicles on the road, you must study and practice to learn to drive carefully and safely. This AZ Licence Exam Simulator mimics the experience of a commercial driver’s exam, pulling 70 random questions from a huge database. The same number of questions (that you can skip) and the same passing score, no hints or explanations. New questions every time you restart.
