Minnesota CDL Test Study Resources

3 min read

Obtaining a Commercial Driver’s License (CDL) in Minnesota requires applicants to pass both knowledge and skills tests that meet the standards set by the Federal Motor Carrier Safety Administration (FMCSA) and the Minnesota Department of Public Safety. Whether you are preparing to drive a school bus, a semi-truck, or a hazardous materials vehicle, proper preparation is essential.

CDL Classes and What They Mean

Minnesota issues three main classes of CDL:

  • Class A: Required for operating vehicles with a combined gross vehicle weight rating (GVWR) of 26,001 pounds or more, including towed units over 10,000 pounds.
  • Class B: For single vehicles with a GVWR of 26,001 pounds or more, or towing a vehicle not exceeding 10,000 pounds.
  • Class C: Needed for vehicles transporting 16 or more passengers (including the driver) or hazardous materials requiring placards.

Each class may require specific endorsements depending on the type of cargo or vehicle configuration.

Required Knowledge Tests

All CDL applicants must pass a general knowledge test. Additional tests may include:

  • Air Brakes Test (if your vehicle is equipped with air brakes)
  • Combination Vehicles Test (for Class A vehicles)
  • Hazardous Materials (HazMat): Requires TSA background check and separate testing
  • Passenger, School Bus, Tank, and Double/Triple Trailer Endorsements

Use the Minnesota CDL Endorsements Explained resource to identify the required exams based on your intended vehicle type.

CDL Skills Testing

After passing the knowledge exams, you must complete the three-part skills test:

  1. Pre-trip Vehicle Inspection
  2. Basic Vehicle Control
  3. On-Road Driving Test

These tests are conducted at authorized Minnesota CDL test sites. You can find out Where to Take the Minnesota Driving Test.

Medical Requirements and Documentation

Before testing, all applicants must meet federal and state medical standards. You must provide a valid Medical Examiner's Certificate (DOT Medical Card). For more on this requirement, refer to the Minnesota CDL Medical Requirements.

Study and Preparation Tips

  • Review the Minnesota Commercial Driver’s Manual thoroughly. It’s available on the Minnesota Department of Public Safety website.
  • Take online practice exams tailored to the CDL class and endorsements you need.
  • Watch training videos and use simulation tools for vehicle control and road driving.
  • Schedule time at a reputable truck driving school if needed.
