One of the key regulations for commercial drivers is the maximum driving hours allowed per day, which is 13 hours in Alberta. Additionally, commercial drivers must take mandatory rest breaks after a certain number of hours on the road. It is also important to be aware of commercial vehicle-specific regulations, such as weight restrictions or the requirement for a commercial operator’s license, and general road rules, such as speed limits and passing restrictions. Failure to adhere to these rules can result in fines, demerit points, and even a commercial operator’s license loss. Commercial drivers must prioritize safety on the road by following all traffic rules and regulations.
