Class B to Class A Upgrade for Montana CDL Applicants
Montana's vast geography and extractive industries create strong demand for flatbed and oversize-load operators. With mining and aggregate, lumber and timber, oil and gas driving much of the freight in Montana, the Class B to Class A Upgrade material below is the part of the Montana CDL that those employers screen for first.
The Montana Class B to A upgrade: Combination Vehicles and Air Brakes knowledge tests at Montana 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 Montana Motor Vehicle Division will schedule the test.
Where Montana drivers use this
- Oil and gas: nearly every oilfield truck runs air brakes
- Almost every Class A and Class B vehicle in Montana; skip this test and your CDL carries an L restriction
- Mining and aggregate: bulk end-dumps, belly-dump hoppers, and heavy-haul equipment moves for the mines
- Oil and gas: crude, fuel, and chemical tankers (N and H endorsements) serving the energy sector
- Agriculture and grain: grain hoppers running from elevators to processors and export terminals
Most Montana CDL work runs the I-90, I-15, I-94 corridors and the Helena 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 Montana Motor Vehicle Division. See the Montana CDL classes and Montana endorsements pages for the full licensing picture.

Topics Covered for Montana Class B to Class A Upgrade Study Material
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.
