Arizona CDL Classes Explained

Which Arizona CDL class you need depends on vehicle weight, what it tows, and the type of operation, not just the truck size. The three classes are set by federal rule (49 CFR 383.91) and are the same in every state, so a Arizona CDL is valid nationwide. Arizona Motor Vehicle Division issues the license and runs the knowledge and skills tests. Arizona serves as a major cross-border freight hub between the US and Mexico along the I-10 corridor.
