Overview

Upgrade prep for Class B CDL holders moving to Class A, including combination vehicles, coupling, air brakes, and HOS theory.

Class B to Class A Upgrade Program for Alaska CDL Applicants

Alaska relies heavily on over-road trucking due to limited rail infrastructure across remote terrain. With oil and gas transport, seafood and cold-chain logistics, military supply chain driving much of the freight in Alaska, the Class B to Class A Upgrade Program material below is the part of the Alaska CDL that those employers screen for first.

The Alaska Class B to A upgrade: Combination Vehicles and Air Brakes knowledge tests at Alaska Division of Motor Vehicles, 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 Alaska Division of Motor Vehicles will schedule the test.

Where Alaska drivers use this

  • Almost every Class A and Class B vehicle in Alaska; skip this test and your CDL carries an L restriction
  • Oil and gas transport: crude, fuel, and chemical tankers (N and H endorsements) serving the energy sector
  • Seafood and cold-chain logistics: refrigerated (reefer) loads of produce and food moving to distribution centers and out of state
  • Military supply chain: defense and government logistics contractors
  • Mining equipment hauling: bulk end-dumps, belly-dump hoppers, and heavy-haul equipment moves for the mines

Most Alaska CDL work runs the AK-1, AK-3 corridors and the Juneau 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 Alaska Division of Motor Vehicles. See the Alaska CDL classes and Alaska endorsements pages for the full licensing picture.

Common Alaska questions

Is this Class B to Class A Upgrade Program material specific to Alaska?
Yes. The knowledge test content is federal (49 CFR 383), so the questions apply in Alaska, and this page adds Alaska details: where you test (Alaska Division of Motor Vehicles), which Alaska industries use this license, and the Alaska corridors the examples are drawn from.
Where do I take the Class B to Class A Upgrade Program knowledge test in Alaska?
Knowledge tests are given by Alaska Division of Motor Vehicles. Bring your Alaska driver license, proof of residency, and your medical certificate; most Alaska offices require an appointment for CDL testing.
How long do I have to study the Alaska 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 Alaska Division of Motor Vehicles with time to spare. Retakes in Alaska 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

Combination Vehicle Dynamics

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.

Coupling and Uncoupling Procedure

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.

Air Line Connections

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.

Trailer and Coupling Inspection

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.

Class A Test Readiness

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.
