How do I prepare for the Kansas CDL knowledge test?
If you are preparing for your first permit, start with general knowledge and the official Kansas 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 Kansas state exam, and it does not copy state test questions. Check the official Kansas 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 Kansas application steps |
Kansas official CDL 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 Kansas.
Kansas Division of Vehicles links its March 2025 commercial manual from the CDL page. Manual section 1.1.1 describes the knowledge tests by vehicle and endorsement. That section and the CDL page checked November 13, 2026 do not print question counts or a knowledge-test passing score. No other state’s figures or federal practice lengths are substituted.

Federal study sets, not the Kansas 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 Kansas test.
