For commercial transportation in Arizona, Interstate 10 runs from Santa Monica, California through Phoenix to Jacksonville, Florida. Another major east-west commercial route is Interstate 40, which runs from Barstow, California through northern Arizona to Wilmington, North Carolina. This highway is a major route for trucks transporting goods between the West Coast and the central United States. Other major commercial routes include U.S. Route 60 and U.S. Route 191. However, commercial drivers should watch out for extreme heat conditions in the summertime, where temperatures of over 110°F can cause tires to blow out or vehicles to overheat. They should also watch out for Arizona’s monsoon season (typically from June to September), with its dust storms, heavy rainstorms, and flash floods.
To drive commercially, you must have a Commercial Driver’s License (CDL). There are three classes of CDLs. A Class A CDL is typically for operating semi-trucks and tractor-trailers. A Class B CDL is typically for operating buses or straight trucks, including most dump trucks. A Class C CDL is typically for operating relatively smaller vehicles designed to transport hazardous materials or 16 or more occupants (including the driver), such as minibuses and small trucks transporting hazardous materials. You must decide which class of CDL you want to apply for, based on the types of vehicles you expect to be driving in your career.
To get a CDL, there are a number of requirements you must meet. Importantly, you must practice commercial driving (under supervision) until you’re able to pass the official skills test on operating a commercial vehicle. To practice, you’ll need a Commercial Learner’s Permit (CLP), for which you must pass the official written knowledge test on the general theory of commercial driving. That’s likely while you’re here. You’ve realized that just reading the official Arizona Commercial Driver License Manual may not give you enough grasp of commercial driving to allow you to pass the knowledge test. (We hope you didn’t learn that lesson the hard way.)
Our practice tests are based on the official manual, just like the official knowledge test. But unlike the official knowledge test, our practice tests promote learning. Each question comes with a helpful hint and an explanation of the correct answer. There’s no pressure to pass, and there’s no embarrassment if you fail. You can learn at your own pace until you’re ready to pass the official test. The free Arizona CDL permit practice test you’re about to take is up to date as of April, 2026. It has 20 questions that address such topics as basic vehicle maneuvers, cargo management, pre-trip inspections, and stopping distances.

To obtain a CDL license in Arizona, start by getting a commercial learner's permit (CLP) after passing the required knowledge tests. Hold the CLP for at least 14 days before taking the CDL skills test. Complete CDL training (optional but recommended) and pass the skills test. Ensure you meet all medical and legal requirements.
The cost for a CDL in Arizona includes a $25 application fee for the CLP, a $12.50 written test fee per endorsement, and a $25 road test fee. The CDL itself costs $25 for a 5-year license.
In Arizona, CDL licenses include Class A (for combination vehicles), Class B (for heavy straight vehicles), and Class C (for vehicles carrying hazardous materials or more than 15 passengers).
The time to get a CDL in Arizona varies. After obtaining a CLP, you must wait at least 14 days before taking the skills test. The duration of CDL training programs, if chosen, can vary from a few weeks to several months.
CDL school is not mandatory in Arizona, but it is highly recommended for comprehensive training and preparation for the CDL skills test. Employers may also require or prefer CDL training program completion.
