To get a CDL, you must first study for and pass the permit exam at the DMV. After you receive your permit, you can take commercial vehicle driving classes and complete the required training. The final step is passing the official driving exam to earn your CDL. Our practice tests help you prepare for the DMV permit exam with real-style questions, and we also provide extra study materials and helpful resources to guide you through the process.
To obtain a CDL in Arizona, you must pass three written permit tests — General Knowledge, Combination Vehicles, and Air Brakes — at the Arizona Department of Motor Vehicles. Similar to a regular driver's license permit exam, these are timed, multiple-choice tests based on the official Arizona CDL handbook.
All of our practice material is built from the official Arizona CDL handbook and federal resources, and curated by professionals with over 10 years of experience in the commercial transportation industry. Studying with practice tests that mirror the real exam format is one of the most effective ways to pass on your first try.
On this page you'll find free practice tests for all three sections. For the full question bank and additional study features, download the CDL Help app.
The CDL knowledge (written) test follows the same federal standards in Arizona as nationwide. Here's what to expect.
Passing score, question counts, and test format are federal standards (FMCSA, 49 CFR Part 383). Always confirm current details with your state's official CDL handbook.
State-charged fees as of June 2026. Amounts change — confirm current fees with the official agency.
The official Arizona Commercial Driver License Manual covers every topic tested on the state's CDL knowledge exam — but it reads like a dense reference manual, not a structured study guide. A more effective way to prepare is with our General Knowledge practice tests. Our free Arizona CDL permit practice test mirrors the format and content of the official exam and is fully up to date as of February 2026. Each practice test features 20 questions covering essential topics such as vehicle inspection, safe driving techniques, air brakes, cargo securement, driving emergencies, hazardous conditions, and Arizona-specific commercial driving regulations. Unlike the official test, every practice question comes with a helpful hint and a detailed explanation of the correct answer — so you actually learn from every question you answer.

Important information about non-domiciled commercial driver's licenses in Arizona.
Federal regulations on non-domiciled CDLs are changing rapidly. The information below reflects the latest known state actions.
Arizona has not published specific state-level details regarding the suspension or status of its non-domiciled CDL program beyond compliance with federal requirements.
Under the FMCSA final rule published on February 13, 2026, eligibility for non-domiciled CLPs and CDLs for foreign-domiciled individuals is now limited to those holding specific, verifiable employment-based nonimmigrant statuses — such as H-2A, H-2B, and E-2 visa holders. Individuals under humanitarian or deferred status categories — including asylum seekers, refugees, and DACA recipients — are no longer eligible. State Driver's Licensing Agencies must verify applicant status through the SAVE database and ensure that no CLP or CDL is issued with a validity period extending beyond the applicant's authorized period of stay. Arizona is expected to comply with these federal requirements. Affected drivers should contact the Arizona DMV or equivalent licensing agency for the most current information.[FMCSA Final Rule]
Federal ELP enforcement applies to all CDL holders nationwide.
Federal ELP enforcement applies to all CDL holders nationwide. Here is how it is enforced in Arizona.
Arizona does not currently administer a separate state-level English Language Proficiency (ELP) test for CDL applicants. However, all Arizona CDL holders are subject to federal ELP enforcement, which took effect on June 25, 2025. Under this enforcement, roadside inspectors conduct a two-step assessment: first, a conversational interview in English — no interpreters or translation tools are permitted — to evaluate whether the driver can communicate sufficiently in English; second, the driver must demonstrate the ability to read and interpret standard U.S. traffic signs. Drivers who fail either step of the assessment are placed out of service under CVSA guidelines. Arizona CDL applicants should be prepared to demonstrate English proficiency during any roadside inspection or compliance review.
