Minnesota CDL permit test: what to expect
The written exam most people call the Minnesota 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 Minnesota, 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 Minnesota's standard comfortably rather than scraping it.
How to get a CDL in Minnesota
To obtain a Commercial Driver's License in the Minnesota, you must first pass the General Knowledge exam. Depending on the type of vehicle you intend to drive, additional endorsements like Air Brakes, Tanker, or Hazmat may be required.

- Hold a valid non-commercial driver's license.
- Pass a Department of Transportation (DOT) medical exam.
- Obtain a Commercial Learner’s Permit (CLP) and wait at least 14 days.
- Pass the skills test in a vehicle of the same class as you intend to drive.

5 Minnesota CDL Practice Questions and Answers
Here are 5 sample Minnesota 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. What is the effect of extremely low temperatures on a vehicle's fuel system?
- A. The fuel pump will operate faster.
- B. Diesel fuel can gel, blocking fuel filters and stalling the engine. (correct answer)
- C. Gasoline will spontaneously combust.
- D. The fuel efficiency will double.
Why: In extreme cold, diesel fuel can cloud and gel, which clogs the fuel filters and lines, causing the engine to starve for fuel and shut down.
2. What is the most effective way to extinguish a tire fire?
- A. Using a B:C rated fire extinguisher.
- B. Using water or dirt to cool the tire. (correct answer)
- C. Driving the vehicle until the fire blows out.
- D. Using a dry chemical extinguisher.
Why: Water is the most effective way to put out a tire fire because it cools the tire. If water is not available, dirt can be used to smother it. Tires contain rubber which holds intense heat.
3. How does nighttime driving affect your total reaction distance when a hazard appears?
- A. Your physical reaction time is faster because you are tense
- B. The vehicle's brakes engage faster in cooler night temperatures
- C. Your physical reaction time is the same, but you see hazards much later, increasing the effective distance you travel before reacting (correct answer)
- D. You do not need as much reaction distance at night
Why: While your physical brain-to-foot reaction time may remain the same, limited visibility means you spot hazards later. This delays the start of your reaction, consuming more distance before braking begins.
4. Coasting with the transmission in neutral or with the clutch depressed is...
- A. A good way to save fuel on long grades.
- B. Legal only in certain states.
- C. Dangerous and illegal, as it removes the engine braking effect. (correct answer)
- D. Recommended when driving on flat terrain.
Why: Coasting in neutral or with the clutch disengaged is illegal in most jurisdictions because it disconnects the engine from the drivetrain, severely reducing vehicle control.
5. When placing warning triangles after a breakdown, why are they placed at 10, 100, and 200 feet?
- A. To satisfy the manufacturer's warranty.
- B. To give approaching drivers adequate visual warning time to see them and change lanes safely. (correct answer)
- C. Because triangles do not reflect light properly at other distances.
- D. To prevent pedestrians from walking near the truck.
Why: Proper spacing of warning devices provides approaching traffic enough time to see the hazard and safely avoid it.
