To meet Arizona CDL requirements, you need to be at least 18 (21 for interstate driving or hauling hazardous materials), hold a regular Arizona driver license, pass a Department of Transportation physical, complete federally mandated Entry-Level Driver Training, pass a written knowledge test for a Commercial Learner Permit, wait 14 days, and then pass a three-part skills test at an Arizona Motor Vehicle Division (MVD) CDL office.1Arizona Department of Transportation. Commercial Driver License (CDL) The whole process is run by the MVD, which handles knowledge tests at any office and skills tests at designated CDL locations.
Who Needs a CDL in Arizona
You need a commercial driver license to operate a vehicle with a gross vehicle weight rating above 26,001 pounds, to tow a trailer rated above 10,000 pounds when the combination exceeds 26,001 pounds, to carry 16 or more passengers (including yourself), or to transport placarded hazardous materials.2Arizona Department of Transportation. Driver License Classes and Types Driving a commercial vehicle without the right class or endorsement is a class 3 misdemeanor under Arizona law.3Arizona Legislature. Arizona Revised Statutes 28-3481 – Commercial Motor Vehicle Drivers Violations Classification
Pick Your Class and Endorsements First
Federal rules split commercial vehicles into three groups, and Arizona follows the same structure.4eCFR. 49 CFR 383.91 – Commercial Motor Vehicle Groups Class A covers combination vehicles over 26,001 pounds when the towed unit exceeds 10,000 pounds, which includes most tractor-trailers. Class B covers single vehicles over 26,001 pounds, including straight trucks, large buses, and dump trucks. Class C covers smaller vehicles designed to carry 16 or more passengers or to haul placarded hazmat.
A Class A license lets you drive Class B and C vehicles, and Class B covers Class C. If you expect to drive different vehicle types over your career, testing in the highest class you qualify for gives you the most flexibility.
Endorsements expand what you can haul or who you can carry, and most require an extra knowledge test. The common ones in Arizona:5Arizona Department of Transportation. Getting Your Commercial Driver License (CDL)
- H (Hazardous Materials): $10, plus a TSA security threat assessment.
- N (Tank Vehicle): $10, for tanks rated at 1,000 gallons or more.
- P (Passenger): $10, with its own skills test.
- S (School Bus): no additional fee, with both a knowledge and a skills test.
- T (Doubles/Triples): $10, knowledge test only.
The hazmat endorsement is the one with real lead time. The TSA background check and fingerprinting cost $85.25 ($41 if you already hold a Transportation Worker Identification Credential), the assessment is good for five years, and processing can exceed 45 days. TSA recommends starting at least 60 days before you need the endorsement.6Transportation Security Administration. HAZMAT Endorsement
Age, Vision, English, and Medical Rules
Arizona’s minimum age is 18 for drivers who stay entirely within the state. If you plan to cross state lines or haul hazardous materials, the federal minimum is 21.7Arizona Legislature. Arizona Revised Statutes 28-3101 – Driver License Classes You also need a valid non-commercial Arizona license before you apply.
Federal Motor Carrier Safety Administration (FMCSA) rules require that you can read and speak English well enough to understand road signs, communicate with law enforcement, and complete reports. Vision standards are specific: 20/40 acuity or better in each eye, a horizontal field of vision of at least 70 degrees in each eye, and the ability to distinguish red, green, and amber traffic signals.8eCFR. 49 CFR 391.41 – Physical Qualifications for Drivers
You confirm those physical standards through a DOT medical exam. The provider must be listed on the FMCSA’s National Registry of Certified Medical Examiners, and a passing exam produces a Medical Examiner’s Certificate (Form MCSA-5876).9Federal Motor Carrier Safety Administration. Medical Examiners Certificate (MEC), Form MCSA-5876 You’ll also file an Arizona CDL Self-Certification form (40-5101) stating whether your driving will be interstate or intrastate, excepted or non-excepted. Most new applicants are non-excepted interstate or non-excepted intrastate, meaning they have to keep a current medical certificate on file. Pick the wrong category and your license record won’t match your medical documentation.
Documents to Bring to the MVD
Arizona law requires proof of your full legal name, date of birth, and lawful presence in the United States. A certified birth certificate or valid U.S. passport works as primary ID. You also provide your Social Security number, which is verified against federal records.10Arizona Legislature. Arizona Code 28-3158 – Driver License or Instruction Permit Application
For residency, bring one document showing your Arizona address: a utility bill, rental agreement, or similar mail from a business, organization, or government agency. Temporary housing or shelter documentation doesn’t qualify.11Arizona Department of Transportation. CDL Documentation Requirements Add your medical certificate and self-certification form, and you’re ready to apply.
Entry-Level Driver Training (ELDT)
Since February 2022, federal rules require anyone applying for a first-time Class A or Class B CDL, upgrading from Class B to Class A, or adding a passenger, school bus, or hazmat endorsement to complete Entry-Level Driver Training through an FMCSA-registered provider.12Federal Motor Carrier Safety Administration. Entry-Level Driver Training (ELDT) You cannot schedule the CDL skills test until your training provider reports your completion to the FMCSA Training Provider Registry.13Federal Motor Carrier Safety Administration. ELDT Applicability
ELDT has a theory portion and a behind-the-wheel portion. There’s no mandated minimum hour count — the program is competency-based. You need at least 80 percent on the theory assessment, and your instructor has to document that you’re proficient in every element of the driving curriculum. Simulators don’t substitute for behind-the-wheel time.14Federal Motor Carrier Safety Administration. ELDT Curricula Summary Theory covers inspections, basic control, shifting, backing, speed and space management, hazard perception, cargo handling, hours-of-service rules, and post-crash procedures. Range and road work covers backing exercises, turns, lane changes, highway entry and exit, and for Class A applicants, coupling and uncoupling.
Costs vary widely. A short program can run a few thousand dollars; a comprehensive school can run $7,000 or more. Some trucking companies sponsor training in exchange for an employment commitment after graduation.
The Commercial Learner Permit and 14-Day Wait
Before you take the skills test, you need a Commercial Learner Permit (CLP). Knowledge tests for the CLP are available at any Arizona MVD office, not just CDL-designated locations. Bring your application, identification, medical certificate, self-certification form, and the permit fee: $25 for a Class A or B permit, $12.50 for Class C.5Arizona Department of Transportation. Getting Your Commercial Driver License (CDL)
You’ll take a general knowledge exam, plus additional written tests for any endorsements you’re adding (air brakes, tanker, hazmat, and so on). Once you pass, the MVD issues your CLP, which is valid for up to 12 months.
A mandatory 14-day waiting period begins the day the CLP is issued. You can’t take the skills test until those two weeks are up and any required ELDT training is complete. During the wait, you can practice driving under the direct supervision of a licensed CDL holder in the front passenger seat.
The Skills Test and the Restrictions Trap
The CDL skills test has three parts, and you need to pass all of them:15Arizona Department of Transportation. CDL Examination Program
- Pre-trip inspection. You walk around the vehicle and identify key components, describing what you’re checking and why.
- Basic vehicle control. In a controlled area, you perform straight-line backing, offset backing, and alley docking. This is where most failures happen.
- On-road driving. You drive in real traffic while the examiner evaluates your turns, lane changes, merging, speed, and overall safety awareness.
You have to bring a vehicle that matches the class you’re testing for; the MVD doesn’t provide one. If you don’t have access to one, authorized third-party examiners may offer a vehicle along with the test for a separate fee. State fees for the skills test are $25 for Class A or B and $12.50 for Class C.
The vehicle you test in also determines what you’re allowed to drive. Two restrictions trip up new drivers more than any others. Test in an automatic and your license is restricted to automatics (Code E); removing it means retesting in a manual. Skip the air brake knowledge test, miss air brake components during the pre-trip, or test in a vehicle without a full air brake system, and you’ll carry an air brake restriction (Code L). Because the vast majority of Class A trucks use air brakes, that restriction can lock you out of most over-the-road jobs. Testing in a manual with a full air brake system is harder on the day and keeps your options open for years.
After passing all three components, you return to an MVD office for final processing. Any previous non-commercial license credentials have to be surrendered — federal and state law both require it.16Arizona Department of Transportation. Transfer Your CDL You’ll receive a temporary paper credential while your permanent card is mailed to your Arizona address.
Register with the FMCSA Clearinghouse
Every CDL and CLP holder must register with the FMCSA Drug and Alcohol Clearinghouse, a federal database that tracks drug and alcohol violations across the industry.17FMCSA Drug and Alcohol Clearinghouse. Registration: CDL Drivers Employers are required to query the Clearinghouse before hiring you and at least once a year while you’re employed, and you have to consent to those queries.18FMCSA Drug and Alcohol Clearinghouse. Query Plans Registration is free and done online. A violation in the database blocks you from safety-sensitive work until you complete a return-to-duty process.

Keeping Your License in Good Standing
Arizona CDLs are valid for up to eight years. The medical certificate on file has its own clock, usually two years, though some conditions shorten it. You are responsible for keeping a valid certificate on file with the MVD at all times. If it lapses, the MVD can downgrade or suspend your commercial driving privileges even when the plastic card in your wallet hasn’t expired. That renewal date is the most common ongoing obligation CDL holders overlook.
