Maine CDL permit test: what to expect
The written exam most people call the Maine CDL permit test is the general knowledge test, and passing it is what gets you a commercial learner's permit rather than the license itself. You need 80% to pass, a federal standard that is the same in every state. The number of questions is set by Maine, and our practice tests use the common 50-question format.
Once you hold the permit you have to keep it for at least 14 days before you are allowed to attempt the skills test, so it is worth sitting the written exam as early as you can. Practice below until you are clearing Maine's standard comfortably rather than scraping it.

5 Maine CDL Practice Questions and Answers
Here are 5 sample Maine general knowledge questions with the right answer and a quick explanation for each. Read through them, then take the quiz above to see how you do without looking.
1. Under which condition should you turn your retarder off?
- A. When operating in heavy stop-and-go traffic
- B. When traveling down a steep, dry mountain grade
- C. When hauling a load that exceeds 80,000 pounds
- D. When driving on wet, icy, or snow-covered roads (correct answer)
Why: Retarders can cause the drive wheels to lock up and skid on poor traction surfaces. They should be turned off on wet, icy, or snow-covered roads.
2. Compared to daytime driving, your following distance at night should be:
- A. Increased, because it is harder to judge distance and speed at night (correct answer)
- B. Determined only by the posted speed limit
- C. Shorter, so you can clearly see the vehicle's taillights
- D. Exactly the same as during the day
Why: At night, depth perception and the ability to judge the speed of vehicles ahead are impaired. You should increase your following distance to give yourself more time to react.
3. What should you do regarding visibility during twilight hours (dawn or dusk)?
- A. Wait until it is completely dark to turn on lights.
- B. Use parking lights only.
- C. Use high beams continuously.
- D. Turn on your headlights early to ensure you are seen by others. (correct answer)
Why: Twilight makes it difficult to see and be seen. Turning on your headlights helps other drivers spot your vehicle.
4. What is the correct procedure for steering to avoid a crash?
- A. Keep one hand on the steering wheel and the other on the horn.
- B. Turn the steering wheel as far as it will go in one direction.
- C. Keep both hands on the steering wheel and do not turn any more than needed to clear whatever is in your way. (correct answer)
- D. Apply the brakes firmly while steering sharply.
Why: When making an evasive steering maneuver, keep both hands on the wheel and do not turn more than necessary. Avoid braking while turning, as it can cause the wheels to lock and result in a skid.
5. You are approaching a railroad crossing with no flashing lights, but your view of the tracks is partially blocked. What should you do?
- A. Stop completely on the tracks to look both ways.
- B. Sound your air horn and proceed at the speed limit.
- C. Slow down, roll down your window, and be prepared to stop if a train is approaching. (correct answer)
- D. Accelerate quickly to clear the tracks before a train arrives.
Why: If you do not have a clear view of the tracks, you must slow down enough to be able to stop before the crossing if a train appears. Rolling down the window helps you listen for an approaching train.
