How many classes of commercial driver's licenses are recognized in Arizona?

Answer: C — Three

In Arizona, there are three classes of commercial driver's licenses, each designed for different types of commercial vehicles and their intended uses. Class A is for drivers who operate a combination of vehicles with a gross combination weight rating (GCWR) of 26,001 pounds or more, such as tractor-trailers or large truck and trailer combinations. Class B is for drivers of single vehicles with a gross vehicle weight rating (GVWR) of 26,001 pounds or more, which includes buses, large vans, or box trucks. Class C is for drivers who operate vehicles designed to transport 16 or more passengers (including the driver) or hazardous materials in amounts that require placarding. Each class has its own set of requirements and testing protocols that reflect the different responsibilities associated with operating larger or more specialized vehicles. This classification ensures that drivers are properly trained and qualified to handle the unique challenges of driving commercial vehicles.
