Class B to A Upgrade Theory for Indiana CDL Applicants
Indiana sits at the crossroads of major Midwest freight lanes supporting automotive and manufacturing supply chains. With automotive manufacturing, steel and metals, pharmaceutical distribution driving much of the freight in Indiana, the Class B to A Upgrade Theory material below is the part of the Indiana CDL that those employers screen for first.
Upgrading from Class B to Class A in Indiana means passing the Combination Vehicles knowledge test at Indiana Bureau of Motor Vehicles (and Air Brakes if not already held), then a skills test in a Class A combination. This is the theory part.
Where Indiana drivers use this
- Automotive manufacturing: just-in-time parts loads between assembly plants and suppliers
- Steel and metals: flatbed and step-deck loads of steel, lumber, and building materials
- Food processing: regional and over-the-road tractor-trailer distribution runs
- Required for any Class A CDL issued in Indiana
- Automotive manufacturing: just-in-time parts hauling between assembly plants and suppliers
Most Indiana CDL work runs the I-65, I-70, I-74 corridors and the Indianapolis 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 Indiana Bureau of Motor Vehicles. See the Indiana CDL classes and Indiana endorsements pages for the full licensing picture.

Topics Covered for Indiana Class B to A Upgrade Theory
Moving from Class B to Class A means operating vehicles with very different handling: longer wheelbase, trailer swing, and off-tracking on turns. This module explains the physics behind combination vehicle behavior as tested on the Combination Vehicles knowledge exam.
Proper coupling procedure is a primary topic on the Combination Vehicles written test and a required demonstration during the Class A skills test. You will learn the sequence that must be followed correctly to pass both the written and practical portions.
Connecting and managing the service and emergency air lines between tractor and trailer is a skill Class B drivers do not typically practice. The exam tests both the correct connection procedure and what happens when those connections fail at speed.
Class A drivers commonly operate in interstate commerce, where federal Hours of Service rules govern maximum drive time, required rest periods, and logging requirements. This section covers the limits, exceptions, and logging concepts that appear on the CDL knowledge exam.
