What is required to legally operate a commercial vehicle in Arizona?

To legally operate a commercial vehicle in Arizona, a driver must possess a commercial driver's license (CDL) along with specific endorsements that correspond to the types of vehicles they are operating or any special cargo they may be hauling.

A commercial driver's license is crucial because it ensures that the driver has met specific training and testing requirements that address the complexities and responsibilities associated with driving larger and more hazardous vehicles compared to standard passenger vehicles. Furthermore, certain endorsements may be required for operating specific vehicle types, such as buses, tankers, or vehicles carrying hazardous materials.

While a valid driver's license is necessary, it does not suffice for commercial vehicle operation due to the higher standards set for safety and regulation in commercial driving. Insurance coverage is also a requirement for commercial vehicles but is separate from the licensing needed to operate the vehicle. Similarly, a vehicle registration certificate is essential for the legality of a vehicle itself but does not pertain to the driver's qualifications. Hence, possessing a CDL with appropriate endorsements is the accurate and necessary requirement for operating commercial vehicles in Arizona.
