You’re planning to get your Commercial Driver’s License in Arizona — and you picked a state that puts drivers to the test in unique ways. Arizona’s trucking industry moves freight through some of the most diverse terrain in the country, from the searing Sonoran Desert floor to 7,000-foot mountain passes near Flagstaff, along corridors like I-10, I-17, and I-40 that connect the Southwest to national supply chains. With Phoenix serving as a major logistics and distribution hub for companies like Amazon, Walmart, and Target, qualified CDL holders are in steady demand.
But before you can haul copper from the Morenci mine, transport winter produce from Yuma, or drive a tanker through the Phoenix metro sprawl, you need to pass the Arizona CDL exam. The Arizona Department of Transportation (ADOT) Motor Vehicle Division (MVD) administers the CDL program under federal FMCSA guidelines, and the process is rigorous by design — because the driving conditions here demand it.
This guide gives you everything you need to prepare for the Arizona CDL test: exact test format, Arizona-specific requirements, what makes driving here different from other states, and free practice tests covering every knowledge exam you’ll face.

Arizona CDL Requirements: What You Need to Know
Arizona follows the federal CDL standards established by the FMCSA under 49 CFR Part 383, with state-specific requirements administered by the Arizona Department of Transportation (ADOT) Motor Vehicle Division. Here’s exactly what Arizona requires:
Age Requirements in Arizona
| License Type | Minimum Age | Restrictions |
|---|---|---|
| Intrastate (Arizona only) | 18 years | Cannot drive across state lines |
| Interstate (all states) | 21 years | No state-line restrictions |
| HazMat Endorsement | 21 years | Federal requirement — no exceptions |
Arizona CDL Fees
| Fee Type | Amount | Details |
|---|---|---|
| CLP Application | $25 | Valid for 180 days |
| CDL Application | $25 | One-time application fee |
| CDL License (5-year) | $25 | Standard renewal cycle |
| CDL License (8-year) | $50 | Extended renewal cycle |
| Endorsements | $10 each | Per endorsement added |
| HazMat Endorsement | $10 + ~$86 | Endorsement fee plus TSA background check |
| Knowledge Test | $15 each | Per knowledge test attempt |
Arizona’s CDL fees are notably lower than many states — one of the advantages of getting your license here. You can manage transactions through the MVD Now online portal, which lets you schedule appointments, pay fees, and handle certain transactions without visiting an office.
Arizona ELDT Requirements
Since February 7, 2022, all new CDL applicants in Arizona must complete Entry-Level Driver Training (ELDT) through an FMCSA-approved training provider. This is a federal requirement — no state can waive it. Arizona MVD verifies ELDT completion electronically through the FMCSA Training Provider Registry (TPR).
ELDT is required for:
- Original Class A or Class B CDL
- Upgrading from Class B to Class A
- First-time School Bus (S), Passenger (P), or HazMat (H) endorsements
You must hold your Commercial Learner’s Permit (CLP) for at least 14 days before taking the skills test. Your CLP is valid for 180 days in Arizona.
Arizona CDL Test Format: What to Expect
The Arizona CDL exam has two parts: knowledge tests (written) and a skills test (driving). The knowledge tests are computer-based, multiple-choice, and administered at Arizona MVD offices or approved third-party testing facilities. You can schedule your tests online through the MVD Now portal.
Knowledge Tests Overview
| Test | Questions | Pass Score | Required For |
|---|---|---|---|
| General Knowledge | 50 | 80% (40 correct) | All CDL classes |
| Air Brakes | 25 | 80% (20 correct) | Class A & B (if vehicle has air brakes) |
| Combination Vehicles | 20 | 80% (16 correct) | Class A |
| HazMat (H) | 30 | 80% (24 correct) | HazMat endorsement |
| Tanker (N) | 20 | 80% (16 correct) | Tanker endorsement |
| Passenger (P) | 20 | 80% (16 correct) | Passenger endorsement |
| School Bus (S) | 20 | 80% (16 correct) | School bus endorsement |
| Doubles/Triples (T) | 20 | 80% (16 correct) | Double/triple trailers |
All Arizona CDL knowledge tests follow FMCSA content standards from the Arizona CDL Manual. The passing score is 80% on every test — no exceptions.
Arizona Skills Test: Three Parts
The Arizona CDL skills test is administered by MVD-authorized third-party testers — many of which are operated through CDL training schools. You must provide your own vehicle for the test, and it must be the same class of vehicle you’re applying for.
| Section | What It Tests | Details |
|---|---|---|
| 1. Pre-Trip Inspection | Vehicle safety knowledge | Verbally identify and explain critical components: engine, brakes, tires, lights, coupling systems |
| 2. Basic Vehicle Control | Backing and maneuvering | Straight-line backing, offset backing, parallel parking, alley dock |
| 3. On-Road Driving | Real-world driving | Lane changes, turns, braking, gear usage, speed management, traffic law compliance |
Arizona retake policy: If you fail a knowledge test, you must wait at least 1 day before retaking. The same 1-day waiting period applies to skills test failures. You’ll pay the full test fee again for each retake. We recommend using our practice tests until you consistently score above 80% before heading to the MVD.
What Makes Arizona CDL Different from Other States?
The core CDL exam is federally standardized — the General Knowledge, Air Brakes, and endorsement tests cover the same material in every state. But Arizona’s unique geography and economy create driving conditions you won’t find anywhere else:
Arizona-Specific Driving Conditions
- Extreme desert heat: Southern and central Arizona regularly sees temperatures above 110°F from May through September. Tire blowouts, engine overheating, and brake fade are constant concerns. Drivers must check tire pressure frequently and monitor engine temperatures — skills tested indirectly on the CDL pre-trip inspection exam
- Dust storms (haboobs): Massive dust walls can reduce visibility to zero in seconds, especially during Arizona’s monsoon season (June–September). ADOT’s “Pull Aside, Stay Alive” campaign teaches drivers to immediately exit the roadway and turn off lights when a dust storm hits — critical safety knowledge
- Steep mountain grades: I-17 between Phoenix and Flagstaff climbs over 5,000 feet in elevation with grades reaching 6-7%. The Mogollon Rim region features winding mountain roads on SR-87 and SR-260. Proper downhill braking technique and gear selection are essential
- Monsoon thunderstorms: July through September brings intense thunderstorms that cause flash flooding — especially in desert washes that cross highways. I-10 south of Phoenix and routes through the Colorado Plateau are particularly vulnerable
- Copper mining industry: Arizona is America’s largest copper producer. Mines at Morenci, Bagdad, and Ray require heavy-haul transport of ore and equipment — making tanker and HazMat endorsements especially valuable in this state
- Major distribution hub: Phoenix has become a Southwest logistics capital for Amazon, Walmart, Target, and other retailers. The I-10, I-17, US-60, and Loop 101/202 freeway system keeps freight moving through one of the fastest-growing metro areas in the country
- Winter driving at elevation: While Phoenix stays mild, Flagstaff and northern Arizona get heavy snow at 7,000+ feet. I-40 and I-17 can require chain restrictions and are subject to closures during winter storms
- Agriculture in Yuma: Yuma County produces over 90% of the nation’s winter leafy greens. Refrigerated freight from Yuma keeps produce moving nationwide — tankers and combination vehicles are in high demand
- Tribal lands: Many Arizona highways cross Native American reservations, including the Navajo Nation, which has its own commercial vehicle regulations. Drivers need to be aware of jurisdictional differences
While the CDL knowledge test won’t ask Arizona-specific geography questions, understanding these conditions will make you a safer driver and help you contextualize the safety rules you’re learning. Heat management, desert survival, and mountain-grade braking are real skills you’ll use daily as an Arizona CDL holder.

Arizona CDL skills tests are administered by MVD-authorized third-party testers — many of which are CDL training schools that offer testing on-site. Testing locations are available throughout the state, including Phoenix, Tucson, Mesa, Glendale, Chandler, Flagstaff, Yuma, Prescott, Sierra Vista, and Kingman. You must provide your own vehicle for the test — it must match the class of license you’re applying for.
