Michigan CDL practice test
The CDL general knowledge test follows federal standards, so these questions apply in Michigan just as they do nationwide — it is the same test that earns your MI commercial learner's permit (CLP). Below the test you'll find the Michigan-specific steps to actually get licensed.

Michigan endorsement tests
General knowledge is the test above. Each endorsement has its own written test and its own question pool — practise the ones your job needs, with the MI steps on each page.
Getting your CDL in Michigan
In Michigan, apply through the state licensing agency (MI DMV / DOT). The core steps are the same across states:
- Get a valid MI driver's license and provide required identity documents.
- Pass the DOT physical with a certified medical examiner and carry your medical card.
- Pass the written knowledge tests (general knowledge plus any endorsements you need).
- Hold your commercial learner's permit (CLP) for the required waiting period.
- Complete Entry-Level Driver Training (ELDT) with a registered provider, if required.
- Pass the skills test — pre-trip inspection, basic controls, and road test.
Exact fees, permit hold times, and document requirements are set by Michigan. Confirm the current details with the MI licensing agency before you go.
What is different in Michigan
Licensing in Michigan runs through the Michigan Department of State. The part that catches people out is not the test — it is the medical certificate, because the way it reaches the state changed in 2025.
Michigan accepts medical examiner’s certificates only electronically from the National Registry — paper submissions from drivers are not taken. Since 14 June 2025 the Secretary of State is required to check the National Registry of Certified Medical Examiners when issuing a commercial learner’s permit or CDL to anyone certifying as non-excepted interstate.
The state checks the Registry at issuance
Michigan does not just receive your certificate, it looks you up. If your exam has not been transmitted, the branch cannot issue or renew a non-excepted interstate CLP or CDL that day — which makes the examiner’s next-calendar-day reporting deadline your problem too.
Michigan moved to electronic medical certification on 14 June 2025. The Michigan DOT physical page has the rest — what the exam checks, what happens if your certification lapses, and the SOS contacts worth having.
