Class B to Class A Upgrade Program for Ohio CDL Applicants

Ohio is a major Midwest freight hub with multiple crossing interstate corridors and a large automotive supply chain. With automotive manufacturing, steel and metals, e-commerce distribution driving much of the freight in Ohio, the Class B to Class A Upgrade Program material below is the part of the Ohio CDL that those employers screen for first.

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

Where Ohio drivers use this

Agriculture and food processing: refrigerated produce loads to distribution centers and out of state
Required for any Class A CDL issued in Ohio
Automotive manufacturing: dump trucks, mixers, and flatbed tractors on construction routes
Almost every Class A and Class B vehicle in Ohio; skip this test and your CDL carries an L restriction
Automotive manufacturing: just-in-time parts hauling between assembly plants and suppliers

Most Ohio CDL work runs the I-70, I-71, I-75 corridors and the Columbus area, so the examples in the practice questions lean on the vehicles and loads you will see there.

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.
