How do I prepare for the Indiana CDL knowledge test?
If you are preparing for your first permit, start with general knowledge and the official Indiana instructions below. If your vehicle needs air brakes or combination vehicles, add those federal study sets; for hazardous materials, use the separate hazmat set. Compare the state’s published test rules with its current manual before you test. These practice sets teach federal topics and do not copy the state exam.
This page is study material. It is not the Indiana state exam, and it does not copy state test questions. Check the official Indiana pages below before you test.
| Your situation | Start with… |
|---|---|
| A quick first try | Take a 10-question warm-up |
| Ready for a longer attempt | Take the 50-question general knowledge exam |
| Need state rules or documents | Check the Indiana application steps |
Indiana commercial driver manual (PDF) — link checked . Study its rules alongside our federal-standard bank. Our 50-question exam length is a study setting; use the official counts below for Indiana.
Indiana BMV’s CDL manual and Indiana-specific supplement checked November 10, 2026 describe the knowledge tests for your vehicle and endorsements. The testing sections and application page checked do not print question counts or a passing score. Those figures stay unknown here; our practice lengths are study settings.

Federal study sets, not the Indiana exam
Use general knowledge, air brakes, combination vehicles, and hazmat to study the federal topics. Finishing one of those sets does not mean you passed the Indiana test.
