Which document is required to legally drive a commercial vehicle?

To legally drive a commercial vehicle, a Commercial Driver's License (CDL) is required. The CDL serves as proof that the driver has passed the necessary skills and knowledge tests specifically designed for operating large or heavy vehicles, ensuring they are equipped to handle the unique challenges and responsibilities associated with driving commercial trucks.

A CDL is mandatory because commercial vehicles, which include tractor-trailers, buses, and other large transport vehicles, present a higher risk on the road due to their size and weight. The licensing process for a CDL includes both written and practical driving tests, which cover various regulations, safe driving practices, and vehicle operation specifics. Without this specialized license, a driver would not be legally permitted to operate a commercial vehicle, regardless of their experience with standard personal vehicles.

While personal identification, vehicle registration, and insurance are important elements of vehicle operation and ownership, they do not substitute for the required expertise and certification that a CDL signifies.
