About this test

All commercial Class 1 licence applicants need to be 19 years old to apply and hold a full-privilege B.C. driver's licence (Class 5 or 6) or an out-of-province equivalent. To get your Class 1 commercial driver's licence in BC, you'll first need to get a learner's licence before taking your road test for a full-privilege licence. To get your learner's licence, you'll need to pass a general knowledge test, a road signs test, and meet medical standards. If you're planning to drive with air brakes, you'll also have to take the air brake knowledge test. Once you have your learner licence, you'll be on your way to get your full Class 1 Commercial Licence. To obtain it, you'll need to pass a commercial road test, which includes a pre-trip inspection test (including air brakes if applicable), a road test, and a driver's medical exam.
