Indiana CDL General Knowledge: Mountain Driving Test 2026

Indiana is famously flat, but the Indiana CDL mountain driving test still earns its place because commercial routes rarely stay inside state lines in 2026. Loads leaving the Crossroads of America climb Appalachian grades to the east and steeper passes out west, so a Hoosier driver must know grade skills cold. This drill covers selecting a low gear before a descent, using engine braking, and avoiding the brake fade that overheated drums invite.

You will practice judging safe downhill speed, watching for runaway ramps, and managing a heavy load on a long grade. The Indiana general knowledge exam is 50 questions with an 80 percent pass requirement, and mountain technique is fair game.

The Indiana CDL Manual from the Indiana BMV explains proper gear selection and braking on grades, so lean on that commercial driver license manual for the details. Drill these mountain driving questions until controlled descents feel routine, then move to the skid control practice that pairs naturally with them.
