About the Michigan CDL knowledge test
The General Knowledge test is the written exam every CDL applicant sits, whatever class of license they are working toward. The questions come from the Michigan CDL manual, they are multiple choice, and you need 80% to pass. Michigan Department of State gives the test, and passing it is what earns your commercial learner's permit, the permit you hold before taking the skills test in a truck.
What it covers
Our 10 free questions and the full 81-question General Knowledge bank are drawn from these manual sections:
- Vehicle Inspection
- Basic Control of Your Vehicle
- Shifting Gears
- Seeing
- Communicating
- Controlling Speed
- Managing Space
- Seeing Hazards
Endorsements such as HazMat, Tank, Passenger and School Bus are separate written tests on top of this one. See which Michigan CDL endorsements you need before you book anything, because the endorsement you are missing decides which tests you sit.
What Michigan requires
- You must hold your CLP and practice under the supervision of a CDL holder for at least 14 days before the skills test.
- Knowledge tests are taken at a Secretary of State office; fail one and you wait one day before each retake.
- You can get a CLP before finishing Entry-Level Driver Training, but ELDT must be complete before the skills test, and before the HazMat knowledge test.
- After passing the skills test you return to a Secretary of State office to pay the endorsement fee and the $9 correction; the corrected CDL is mailed to you.
- A passed skills test is valid for one year; apply for the CDL within that year or all tests must be retaken.
