Michigan CDL practice test

Getting a commercial driver's licence in Michigan starts with the CDL knowledge tests. The content is federal: every state, Michigan included, writes its tests from the FMCSA CDL manual, so the general knowledge test has 50 questions, the endorsement tests have 20 to 30, and the passing score is 80% on each. The Michigan driver licensing agency administers the test; the rules behind it are published by the FMCSA. Try the free Michigan CDL practice questions below, then pick a full test.

Free Michigan CDL practice questions

Five questions from the general knowledge, air brakes and combination vehicles banks, the three tests most Michigan Class A applicants take first. Show the answer to read the explanation.

  1. In an emergency, what can you usually do more quickly: stop or turn to avoid an obstacle?

    • Stop; braking is always faster than steering
    • Neither; they take the same time
    • Turn; you can almost always turn to miss an obstacle faster than you can stop
    • It depends on the speed limit
    Show answer
    Answer: C. Turn; you can almost always turn to miss an obstacle faster than you can stop

    Stopping takes a long distance at highway speed. A quick steering move is often the better choice, as long as you keep both hands on the wheel and do not turn more than needed.

  2. An oncoming driver has drifted into your lane. The best move is usually to:

    • Steer to the left into the oncoming lane
    • Brake and stay in your lane
    • Flash your lights and keep going straight
    • Steer to the right
    Show answer
    Answer: D. Steer to the right

    Moving right keeps you away from oncoming traffic. If the other driver recovers, you are still on your own side, and the shoulder is usually a better escape route than the opposing lane.

  3. If you must leave the road to avoid a crash, you should avoid braking until your speed has dropped to about:

    • 20 mph
    • 50 mph
    • 40 mph
    • 5 mph
    Show answer
    Answer: A. 20 mph

    Braking on a soft shoulder or dirt can cause a skid or rollover. Keep one set of wheels on the pavement if possible, stay off the brakes until you are down to about 20 mph, and then brake gently.

  4. When returning to the road from the shoulder, you should:

    • Ease back on gradually at highway speed
    • Wait until your speed is low, turn sharply back onto the road, then counter-steer to straighten out
    • Stop fully, then back onto the road
    • Turn the wheel only slightly so the trailer follows
    Show answer
    Answer: B. Wait until your speed is low, turn sharply back onto the road, then counter-steer to straighten out

    If the shoulder is lower than the road, easing back can make the tire catch on the edge and pull the vehicle sharply. A deliberate sharp turn at low speed followed by counter-steering keeps control.

  5. Your hydraulic brakes fail while driving. Which of these actions can help?

    • Shift to neutral and steer for the nearest building
    • Turn the engine off to slow the vehicle
    • Downshift, pump the brake pedal, and use the parking brake while finding an escape route
    • Speed up so the brakes cool down
    Show answer
    Answer: C. Downshift, pump the brake pedal, and use the parking brake while finding an escape route

    Downshifting lets the engine slow you. Pumping may build enough hydraulic pressure to stop. The parking brake works on a separate system, so hold the release so you can let off if the wheels lock, and look for an uphill road or open field to stop in.

Every CDL test for Michigan drivers

Each page has ten free sample questions, the real question count, the 80% pass mark and what the test covers.

How the Michigan CDL knowledge test works

You take the general knowledge test first; it is required for every CDL class. Class A drivers add the combination vehicles test. Almost everyone takes the air brakes test, because skipping it puts an air brake restriction on the licence. Endorsements (hazmat, tanker, doubles/triples, passenger, school bus) each have their own knowledge test. Pass the tests and you hold a commercial learner's permit; the skills test in a truck comes later.

Fees, appointment rules and test centre locations are set by Michigan and change over time, so check the state driver licensing agency before you go. What does not change is the content, and that is what PassRig drills.

Michigan CDL test questions

How many questions are on the Michigan CDL test?

The Michigan CDL general knowledge test follows the federal model: 50 questions, 40 correct to pass. Endorsement tests are shorter: air brakes 25, hazmat 30, and combination vehicles, tanker, doubles/triples, passenger and school bus 20 each.

What is the passing score on the Michigan CDL permit test?

80% on every knowledge test, the same pass mark used across the United States.

Where do I take the CDL knowledge test in Michigan?

At the Michigan state driver licensing agency (the DMV, DOT or equivalent). Check its website for locations, appointments and current fees; the test content itself comes from the FMCSA CDL manual.
