What should you do when merging?
- Merge at a much lower speed than the flow of traffic.
- Use your mirrors to make sure the gap in traffic is large enough for you to enter safely.
- Merge without signaling.
Correct answer: Use your mirrors to make sure the gap in traffic is large enough for you to enter safely.
When you're getting onto a road, make sure there's enough room for your vehicle by checking your mirrors. You should merge into traffic smoothly without going a lot slower than other cars and always signal to let others know what you're doing.
Documents related to hazardous materials transportation must be stored ___.
- In the pouch of the driver door.
- Attached to the sun visor.
- In a box on the trailer.
Correct answer: In the pouch of the driver door.
Keep the papers for hazardous materials in the driver door pouch. This way, they are easy to reach if needed.
Which of these statements about driving through a tunnel is correct?
- Keep windows open for fresh air.
- Turn off all lights inside the truck.
- There may be strong winds when exiting.
Correct answer: There may be strong winds when exiting.
When you drive out of a tunnel, you might feel a strong push of wind.
Among these vehicles, which is more likely to experience off-tracking during turns?
- Tractor with 45-feet trailer.
- 28-feet box truck
- 45-feet straight truck
Correct answer: Tractor with 45-feet trailer.
When a big truck turns, the back end can swing out. This is called off-tracking. A tractor with a 45-feet trailer is more likely to do this because it's longer and the way it's put together makes the back end swing out more when it turns.
Under what circumstances should you sound your horn?
- If it helps to avoid a crash.
- To let others know you are running late.
- To say hello to a friend on the sidewalk.
Correct answer: If it helps to avoid a crash.
Use your horn only if it can help stop an accident from happening.
Identify the incorrect statement regarding alcohol consumption.
- A drinker can control how fast his or her body absorbs alcohol.
- Alcohol goes directly from the stomach to the blood stream.
- BAC is determined by how fast you drink; how much you drink and how much you eat.
Correct answer: A drinker can control how fast his or her body absorbs alcohol.
A drinker can't control how fast his or her body absorbs alcohol.
If your vehicle is missing ____ or more leaves from any leaf spring, it won't be allowed to be used.
- 1/3
- 1/4
- 1/2
Correct answer: 1/4
If a quarter or more of the leaves in any leaf spring are missing, your truck can't be used until it's fixed.
Select the correct statement regarding the transportation of hazardous materials.
- Any truck carrying any amount of hazardous materials must have placards.
- Hazardous materials can be disposed of in regular trash bins if the containers are sealed.
- All hazardous materials present health and safety danger.
Correct answer: All hazardous materials present health and safety danger.
Hazardous materials are always dangerous to health and safety, no matter what kind they are. They can hurt people and the environment, so it's important to handle them carefully.
To figure out how much alcohol is in someone's blood (BAC), you need to know:
- Their height.
- The time of day they drink alcohol
- Their weight.
Correct answer: Their weight.
An individual's body weight plays a central role in determining how alcohol disperses throughout the body. Essentially, a lighter person will have a higher concentration of alcohol in their bloodstream after consuming the same amount as someone heavier.
What is the right way to hold a steering wheel?
- With one hand on the top of the wheel and the other on your lap.
- With your knees, while using your hands to adjust the radio.
- With both hands, on opposite sides of the wheel.
Correct answer: With both hands, on opposite sides of the wheel.
The correct way to hold a steering wheel is with both hands placed on opposite sides of the wheel. This gives you the most control over the vehicle, making it safer to drive.

Your Path to a Commercial Driver's License
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 the written permit tests that match your license class — General Knowledge for everyone, plus Combination Vehicles and Air Brakes where they apply — 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. All 2,500+ questions and the study tools are in the app with a subscription — download the CDL Help app.
Arizona CDL Knowledge Test: Format & Requirements
The CDL knowledge (written) test follows the same federal standards in Arizona as nationwide. Here's what to expect.
Questions by test
The 80% passing score is a federal standard (FMCSA, 49 CFR 383.135). Question counts follow the AAMVA model used by most states and can vary by state. Always confirm current details with your state's official CDL handbook.
Arizona CDL Fees & Licensing
State-charged fees as of June 2026. Amounts change — confirm current fees with the official agency.
CDL Requirements in Arizona
azdotazdotappsazleg49 CFR §391.11
- Citizenship and immigration-status requirements apply and changed under 2026 federal rules — verify your eligibility directly with the Arizona Department of Transportation (ADOT) Motor Vehicle Division (MVD) before applying (see Official Sources below).
- Arizona must be your state of domicile — MVD will not issue a Class A, B or C license or instruction permit to an applicant domiciled in another state (A.R.S. § 28-3153).
- Must be at least 18 years old for an intrastate-only Arizona CDL; 21 to drive interstate or transport placarded hazardous materials (A.R.S. § 28-3153(A)(3)).
- Arizona statute separately bars a Class A, B or C license for anyone who fails to demonstrate English-language proficiency as MVD determines it (A.R.S. § 28-3153(A)(15)).
- Provide proof of U.S. citizenship or lawful permanent residency. MVD also accepts an unexpired foreign passport (excluding Canada and Mexico) paired with an unexpired I-94 or I-94A showing H-2A, H-2B or E-2 status.
- Moving to Arizona with an out-of-state CDL? You have 30 days to convert it, and federal and state law require surrendering every prior license credential.
- Provide proof of at least one year of driving experience — an out-of-state license issued more than a year ago, or a motor vehicle record less than 30 days old (no third-party MVRs accepted).
- Your medical examiner, listed on the FMCSA National Registry, files the Medical Examiner’s Certificate electronically; allow 24 hours before visiting an MVD office. Renew the certificate every 24 months or the CDL is suspended.
- Take every applicable knowledge test in one walk-in visit at any MVD office, 7:30 a.m.–3:00 p.m. Each test needs 80 percent to pass; a failed test can be retaken the next business day.
- Purchase the Commercial Learner’s Permit — $25.00 for Class A or B, $12.50 for Class C — and hold it at least 14 days before scheduling the skills test. The CLP is valid for up to 12 months.
- Entry-Level Driver Training (theory, range and road, from an FMCSA-registered provider) is required before the skills test for a first Class A or B CDL, a Class B-to-A upgrade, or a first School Bus, Passenger or Hazmat endorsement.
- Book the road/skills test at one of MVD’s 12 CDL locations or through an MVD-certified third-party tester (school districts, government agencies and truck driving schools also administer it); you supply the test vehicle.
- Pay the license fee after passing the skills test — $25.00 for Class A or B, $12.50 for Class C. An Arizona CDL is valid for up to 8 years.
- If your CDL sits disqualified, cancelled, suspended or revoked for a year or more, MVD treats it as invalid: you retake every written and skills test and pay all licensing and reinstatement fees again.
Official Arizona CDL Handbook
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.
- Complete CDL regulations and Arizona-specific requirements
- Safe driving techniques, vehicle inspection, and cargo handling
- All endorsement categories and testing requirements

Non-Domiciled CDL Information
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.
MVD folds non-domiciled eligibility into its standard proof-of-status rule rather than running a separate non-domiciled program page: to obtain any Arizona CDL or CLP, the Arizona Commercial Driver License Manual accepts an unexpired foreign passport (excluding Canada and Mexico) together with an unexpired Form I-94 or I-94A showing an H-2A, H-2B or E-2 category, alongside proof that Arizona is your home state under A.R.S. § 28-3153(D) and 49 CFR 383.71.
Under the FMCSA final rule published February 13, 2026 (effective March 16, 2026), that federal document list is now the ceiling nationwide — eligibility for a foreign-domiciled CLP or CDL is limited to H-2A, H-2B and E-2 status, Employment Authorization Documents no longer qualify, and State Driver’s Licensing Agencies must verify status through the SAVE database. Arizona has not published a separate state-level statement pausing or restricting issuance the way some states have. CDL Help does not provide legal or immigration advice, and these requirements are changing quickly — confirm your specific situation directly with the Arizona MVD and the official FMCSA resources linked below.[FMCSA Final Rule]
English Language Proficiency (ELP)
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.

How to get a CDL in Arizona
- Make Arizona your state of domicile and hold an Arizona driver license first — MVD issues a CDL only to Arizona residents, and a CDL holder moving here has 30 days to convert. Source
- Get a DOT physical from a medical examiner on the FMCSA National Registry. The examiner files your Medical Examiner’s Certificate electronically — allow 24 hours before you visit an MVD office. Source
- Bring proof of authorized presence, two proofs of Arizona residence address, your Social Security number and proof of one year of driving experience (an out-of-state MVR must be less than 30 days old), then complete a Commercial Driver License Application at an MVD office. Source
- Pay the fee for the class of permit before testing — $25.00 for a Class A or B permit with no endorsements, $12.50 for a Class C permit — plus $10.00 for each endorsement you are adding. Source
- Take every applicable knowledge test in one visit at any MVD office (walk-in, 7:30 a.m.–3:00 p.m.). You need at least 80 percent on each test; a failed test can be retaken the next business day. Source
- Complete Entry-Level Driver Training with an FMCSA-registered provider if this is your first Class A or B CDL, an upgrade from Class B to Class A, or a first S, P or H endorsement — the curriculum covers theory, range and road. Source
- Hold the CLP at least 14 days, then request a skills-test appointment at any MVD office or by calling MVD — a CDL tester contacts you to schedule. Skills testing runs at 12 MVD locations, and MVD-certified third-party providers (truck driving schools, school districts, government agencies) also administer it. Source
- Bring your own vehicle for the three-part skills test (pre-trip inspection, basic control, road). If you are testing for a passenger or school bus endorsement, test in the size of bus you intend to drive. Source

Arizona CDL questions
- How much does an Arizona CDL cost?
- There is no single fee. MVD charges the class-of-permit fee first ($25.00 for a Class A or B commercial learner permit, $12.50 for Class C), then $25.00 for the road/skills test at a state CDL office ($12.50 for a Class C vehicle), then $25.00 for the Class A or B licence itself ($12.50 for Class C) — plus $10.00 for each endorsement (doubles/triples, tank, HazMat, passenger; school bus is free, motorcycle $7.00). There is no separate knowledge-test fee: you pay for the class of licence before you test. A third-party tester sets its own skills-test price, which MVD does not publish. Source
- How long is an Arizona commercial learner permit good for?
- A maximum of 12 months. You must hold it for at least 14 days before taking the skills test, and an out-of-state CLP is not transferable to Arizona. A HazMat endorsement can never be placed on a permit; a Class C permit must instead carry a passenger endorsement. Source
- What score do I need on the Arizona CDL knowledge test, and where do I take it?
- At least 80 percent on each knowledge test. Testing is walk-in at any Arizona MVD office between 7:30 a.m. and 3:00 p.m. — no appointment necessary — and you take all applicable tests during the same visit. If you fail, you wait until the next business day to retake. Source
- How do I take the CDL skills test in Arizona?
- By appointment only. Request one at any MVD office or by phoning MVD; a CDL tester then calls you back to schedule. MVD runs skills testing at 12 locations, seven of which have moved to the Modernized CDL Skills Test, and MVD-certified third-party providers — truck driving schools, school districts, government agencies — can also administer it. You supply the test vehicle. Source
- How old do you have to be to get a CDL in Arizona?
- MVD sets the minimum at 18, but a driver under 21 can only hold an intrastate CDL valid inside Arizona and may not transport hazardous materials. Arizona statute (A.R.S. § 28-3153(A)(3)) puts it the other way round: no Class A, B or C licence under 21, except one restricted to intrastate driving from age 18. Source
