About the Michigan CDL test

Drivers aged 18 to 21 may operate a commercial vehicle only inside Michigan; interstate driving and placarded hazardous materials require age 21. The department does not publish the number of questions on the general knowledge test, so the values here are a working configuration listed as unconfirmed.
