Class B to Class A Upgrade Program for Arizona CDL Applicants
Arizona serves as a major cross-border freight hub between the US and Mexico along the I-10 corridor. With semiconductor and electronics distribution, construction materials, agriculture produce driving much of the freight in Arizona, the Class B to Class A Upgrade Program material below is the part of the Arizona CDL that those employers screen for first.
The Arizona Class B to A upgrade: Combination Vehicles and Air Brakes knowledge tests at Arizona Motor Vehicle Division, then a Class A skills test. Since February 2022, ELDT theory and behind-the-wheel training must also be logged with an FMCSA-registered provider before Arizona Motor Vehicle Division will schedule the test.
Where Arizona drivers use this
- Cross-border freight: international tractor-trailer lanes
- Required for any Class A CDL issued in Arizona
- Semiconductor and electronics distribution: dump trucks, mixers, and flatbed tractors on construction routes
- Almost every Class A and Class B vehicle in Arizona; skip this test and your CDL carries an L restriction
- Semiconductor and electronics distribution: regional and over-the-road distribution runs for grocery, retail, and e-commerce freight
Most Arizona CDL work runs the I-10, I-17, I-40 corridors and the Phoenix area, so the examples in the practice questions lean on the vehicles and loads you will see there.
Testing, appointments, and fees are handled by Arizona Motor Vehicle Division. See the Arizona CDL classes and Arizona endorsements pages for the full licensing picture.
Common Arizona questions
- Is this Class B to Class A Upgrade Program material specific to Arizona?
- Yes. The knowledge test content is federal (49 CFR 383), so the questions apply in Arizona, and this page adds Arizona details: where you test (Arizona Motor Vehicle Division), which Arizona industries use this license, and the Arizona corridors the examples are drawn from.
- Where do I take the Class B to Class A Upgrade Program knowledge test in Arizona?
- Knowledge tests are given by Arizona Motor Vehicle Division. Bring your Arizona driver license, proof of residency, and your medical certificate; most Arizona offices require an appointment for CDL testing.
- How long do I have to study the Arizona Class B to Class A Upgrade Program material?
- Access lasts 120 days from purchase, which is enough to study, take the practice tests, and pass at Arizona Motor Vehicle Division with time to spare. Retakes in Arizona are allowed after a short wait, so a second attempt is covered too.
When Is This Useful?
Helps drivers expand from heavy single vehicles into tractor-trailers and other combination vehicle work.
Who Is This For?
Current Class B CDL holders who need Class A authority for new job duties or equipment assignments.
Topics Covered
Upgrading from Class B to Class A means operating vehicles with fundamentally different handling. Off-tracking, rearward amplification, and trailer swing all require new driving habits. The Combination Vehicles written test focuses on these differences compared to single heavy vehicles.
Correctly connecting a tractor to a trailer is a critical Class A skill tested both on the written exam and during the skills test. This module covers the exact coupling sequence that examiners expect to observe during the pre-trip exercise.
Class A combination vehicles use service and emergency air lines between the tractor and trailer that Class B drivers have not typically operated. You will learn how to connect them correctly, perform pressure checks, and identify warning signs of failure.
Adding a trailer to your pre-trip inspection means covering the coupling area, fifth wheel, air connections, trailer brakes, and landing gear in sequence. The Class A skills test expects you to demonstrate all of these additional inspection points.
The Class A upgrade requires passing the Combination Vehicles written knowledge test plus completing a new skills test on a Class A vehicle. This section prepares you for the content differences, scoring criteria, and what Class A evaluators assess differently from Class B.
