One such rule is the mandatory use of safety belts by all occupants of commercial vehicles. In addition, commercial drivers must adhere to speed limits posted on highways and local roads, which vary depending on the type of vehicle and the location. Moreover, commercial drivers must always yield to pedestrians and follow traffic signals and signs. They must also maintain a safe distance from other vehicles on the road, especially in adverse weather conditions. Finally, commercial drivers in BC cannot use handheld electronic devices while driving, which is against the law. These traffic rules ensure the safety of the commercial driver and the passengers in the vehicle and contribute to the community’s overall safety.

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.
