Which document must a truck driver carry while operating a commercial vehicle?

A truck driver is required to carry a valid driver's license and vehicle registration while operating a commercial vehicle to ensure compliance with regulatory and safety standards. The valid driver's license confirms that the individual has undergone the necessary training, testing, and certification to operate a commercial vehicle safely. It verifies that the driver is legally permitted to drive and possesses the required skills and knowledge.

Vehicle registration serves as proof that the vehicle is properly registered with the appropriate authorities and complies with provincial laws. Registration documentation can include details such as the vehicle's identification number, make, model, and the registered owner. Carrying both a valid driver's license and vehicle registration is crucial for legal operation and helps facilitate any necessary interactions with law enforcement or regulatory agencies during roadside inspections or traffic stops.

While proof of insurance is essential, having only this document does not fulfill the complete requirement of what must be carried while operating a commercial vehicle. Vehicle maintenance records and a copy of the owner's manual, while important for vehicle upkeep and reference, are not mandatory documents for driving. Thus, the combination of a valid driver's license and vehicle registration is a key requirement for truck drivers.
