In the United States, there are three classes of Commercial Driver Licenses (CDLs). A Class A CDL allows you to operate combination vehicles with a Gross Combination Weight Rating (GCWR) of over 26,000 pounds, in which the towed vehicle weighs more than 10,000 pounds. This class of CDL is typically for driving semi-trucks or tractor-trailers, but it will also let you drive vehicles from classes B and C. A Class B CDL allows you to operate a single vehicle with a Gross Vehicle Weight Rating (GVWR) of over 26,000 pounds, or to tow a vehicle that does not exceed 10,000 pounds. This license is typically for driving large buses (including large school buses) and straight trucks (including box trucks and most dump trucks), but it will also let you drive vehicles in Class C. A Class C CDL allows you to operate relatively smaller vehicles designed to transport hazardous materials or 16 or more occupants (including the driver). This class of CDL is typically used for operating small buses (including shuttle buses) and small trucks carrying hazardous materials. You must decide which class of CDL you want to apply for, based on the types of vehicles you expect to be driving in your commercial driving career.
Before you can obtain a CDL, you must become proficient in commercial driving. To practice commercial driving (under supervision), you must obtain a Commercial Learner’s Permit (CLP). To be eligible for a CLP, you must submit to a medical examination and pass the official General Knowledge test. And we can help you ace that knowledge test.
This free Minnesota CDL permit practice test is based on the official CDL manual (Minnesota CDL Handbook 2026), just like the official knowledge test. It is up to date as of June, 2026. There are 20 questions on such topics as cargo management, emergency preparedness, vehicle components, and vehicle maneuvers. But unlike the official test questions, each of our practice questions includes a helpful hint and an explanation of the correct answer.
For you as a commercial driver in Minnesota, all the stuff you’re learning about how to operate commercial vehicles under winter conditions isn’t just needed to pass the official knowledge test. Minnesota’s winters can be difficult and treacherous for commercial drivers, with subzero temperatures, frequent snowstorms, and roads covered in snow or ice. You may often encounter patches of black ice too. As the winter subsides, the spring thaws can cause flooding, leading to road closures and detours. So, pay careful attention to these driving techniques as you study. They may well come in handy when you start commercial driving in this state!
What to review before the CLP knowledge test and CDL endorsement practice
Based on recent Driving-Tests.org answers for this test family.
Review CDL alcohol limits, out-of-service rules, testing requirements, and penalties for impaired commercial driving.
Review engine controls, shifting, gauges, retarders, and warning signs that need attention before or during a trip.
Review CDL documents, disqualifying violations, out-of-service rules, and penalties that affect commercial driving privileges.
Review tire condition, tread, inflation, lug nuts, rims, and wheel-end problems caught during inspection.
CLP and General Knowledge requirements before skills testing and endorsements
Start with General Knowledge for your MN CLP. Add Combination Vehicles, Air Brakes, or endorsement tests only when they match the license class and endorsements you need.
Passing the written test does not give you a CDL. After your CLP is issued, federal rules require you to hold it for at least 14 days before the CDL skills test.
Pick the right medical self-certification category early. If you drive non-excepted interstate, keep your DOT medical certification current with the state licensing agency.
ELDT may be required before Class A or B skills testing, first-time Passenger or School Bus endorsements, or the HazMat knowledge test. Your training provider submits completion through FMCSA's Training Provider Registry.
Use General Knowledge as the base, then move into the CDL tests that match your license class and endorsements.
