Indiana CDL General Knowledge: Driver Fitness Test 2026

Staying legal on the clock is as much a part of the job as staying between the lines, and this Indiana CDL driver fitness and hours of service test prepares you for both in 2026. It covers medical fitness to drive, the fatigue rules that govern how long you can stay behind the wheel, and the logging duties that keep a career intact. These general knowledge topics protect your license and everyone sharing the road.

Expect questions on daily and weekly driving limits, required rest, and recognizing when you are too tired to continue. The general knowledge exam behind this drill runs 50 questions and requires 80 percent to pass.

Because hours-of-service rules are precise, verify the specifics against the Indiana CDL Manual from the Indiana BMV, the commercial driver license manual examiners rely on. Study these driver fitness and hours questions until the limits stick, then roll into the next general knowledge topic on your list.
