What is the minimum age requirement to apply for an Arizona Class A License?

To apply for an Arizona Class A License, the minimum age requirement is 18 years old. This requirement is in place because operating commercial vehicles requires a higher level of responsibility and a greater understanding of the rules of the road due to the size and weight of these vehicles. Younger drivers may not have the experience or maturity necessary to safely operate large commercial trucks, which is why many states, including Arizona, set the minimum age for a Class A License at 18.

Additionally, the age of 21 is often associated with operating commercial vehicles across state lines, in which case federal regulations apply and set the minimum age at 21 for certain types of commercial driving jobs. However, for obtaining the license itself within the state for intrastate driving, the requirement is 18.
