Class B to Class A Upgrade for Michigan CDL Applicants
Michigan is the heart of US automotive manufacturing, driving strong demand for flatbed and just-in-time parts haulers. With automotive parts and assembly, steel and metals, agriculture and food processing driving much of the freight in Michigan, the Class B to Class A Upgrade material below is the part of the Michigan CDL that those employers screen for first.

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.
