Commercial drivers are responsible for maintaining safety on the road for themselves and other drivers, pedestrians, and the environment. One of the most crucial rules is to obey speed limits and other traffic signs, especially in busy areas or residential neighborhoods. The use of cell phones or any electronic devices while driving is strictly prohibited to prevent driver distraction. Commercial drivers must also undergo drug and alcohol testing to ensure they are fit for duty, as impaired driving can lead to fatal accidents. In addition, commercial vehicles must meet safety standards and be periodically inspected to ensure their fitness for the road. Commercial drivers must abide by these traffic rules and regulations to promote safety and prevent accidents on British Columbia roads.

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.
