Some important traffic rules for commercial drivers include obeying speed limits, stopping at all stop signs and red lights, using proper signals when turning or changing lanes, and maintaining a safe following distance. It is also important to avoid distracted driving, such as using a cell phone or eating while driving, and to always wear a seatbelt. Failure to follow traffic rules as a commercial driver can result in fines, license suspension or revocation, and even criminal charges if serious injuries or fatalities occur. Therefore, it is essential to prioritize safety and obey all traffic laws when operating a commercial vehicle on the roads of British Columbia.

Remember, our tests are similar to the official BC professional drivers test you must take and pass to attain your commercial driver’s licence. No practice test can be the same as the official one, as they change often. Still, 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.
