Question 30 of 30


 

It is recommended that you take a practice test before you take the actual written test. Please note, however, that this is not the actual test, and you will not receive your license if you pass this sample practice test. If you’re getting your commercial licence, you've come to the right place.


Remember, our tests are similar to the official BC professional drivers test that you will have to take and pass in order to attain your commercial driver licence, as there is no practice test that can be the exact same as the official test, as they tend to change often, but nonetheless, by practicing with them in conjunction with your “driving commercial vehicles – a guide for professional drivers” handbook, you will be well on your way to attaining your CDL in a short period of time.
