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

A truck driver is required to carry a valid driver's license and a Commercial Vehicle Operator's Registration (CVOR) certificate at all times while operating a commercial vehicle. The driver's license is essential as it verifies that the operator is legally qualified to drive the specific class of commercial vehicle. The CVOR certificate is equally important as it registers the vehicle operator with the Ministry of Transportation, demonstrating compliance with safety and operational standards necessary for commercial trucking.

Having these documents readily available ensures that the driver can prove their legitimacy to authorities during roadside inspections or traffic stops, which is vital for maintaining safety and regulatory compliance within the industry. While insurance documents, vehicle registration, and weight permits are also significant for truck operation, the combination of a valid driver's license and CVOR is specifically mandated for driver verification and regulatory purposes in Ontario.
