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.
