Wisconsin CDL Practice Tests - All Endorsements

Before you book anything with the state, get your score steady on the tests above. They mirror the written exam Wisconsin gives on the way to a Commercial Learner’s Permit.

Here is what that exam actually is. The CDL General Knowledge test asks 50 questions, and passing means answering 40 of them correctly, an 80 percent line. The FMCSA sets that number, so it does not change when you cross a state border. Because this single test is what earns your CLP, a Wisconsin CDL permit practice test and a general knowledge run are one and the same. Applicants for Class A, B, and C all take it. The letter on your license comes from the skills test and the truck you bring, not from the written portion.

The material rewards steady review over cramming. You will face pre-trip inspection, basic control, shifting through the gears, following distance and speed on the highway, reading hazards before they develop, and what to do when brakes fade or a trailer starts to skid.

Wisconsin puts its own stamp on which endorsements pay off. Dairy runs deep here, and hauling milk is real, ongoing work, so the Tanker endorsement carries weight for drivers moving liquid loads from farm to processor. Milwaukee’s factories and the Port of Milwaukee on Lake Michigan feed steady freight onto I-94, I-90, and I-43, where combination rigs call for the Combination Vehicles and Air Brakes tests. Agriculture, manufacturing, and port work each lean on different skills, so choose your endorsements around the loads you want.

Remember the full endorsement list runs Air Brakes, Combination Vehicles, HazMat, Tanker, Doubles/Triples, Passenger, and School Bus, each a separate knowledge test with its own study.

The Wisconsin Commercial Driver’s Manual covers every topic in plain language, and the free Wisconsin CDL practice tests above need no login. Take one more as a sample CDL exam once you feel ready, and when your results stay above the line, schedule your CDL skills test with the Wisconsin DMV.
