Free Wisconsin CDL Permit Practice Test: General Knowledge 2025

In the great state of Wisconsin, the most important economic sectors are agriculture (including butter, milk, and cheese), manufacturing (including paper products and processed foods), and tourism, all of which have created a demand for commercial drivers. Major commercial routes include Interstates 43, 90, and 94; U.S. Route 41; and State Highway 29. On I-43 and I-94, traffic congestion near major cities is a frequent problem. Furthermore, winter driving conditions on Wisconsin’s roads can be difficult and treacherous; heavy snowfall and icy road surfaces can make some minor roads nearly impassible.

You have a number of requirements you must meet before you may obtain a Commercial Driver’s License (CDL), which will allow you to legally drive commercially. Most importantly, you must become proficient at commercial driving to pass the official skills test. To practice commercial driving (under supervision), you must obtain a Commercial Learner’s Permit (CLP). The requirements for a CLP you must meet include submitting to a physical examination and passing the official General Knowledge test on commercial driving theory.

You have likely been advised to study the official Wisconsin Commercial Driver’s License Manual (Wisconsin CDL Handbook 2025). The manual does contain all the information on which you’ll be tested. However, many aspiring drivers have found it difficult to absorb and retain much of the information in the manual. If you’re having the same problem, we can help you with some additional study tools.

This free Wisconsin CDL permit practice test you’re about to take will evaluate your understanding of certain commercial driving topics. It’s based on the official CDL manual, just like the official knowledge test. And it’s up to date as of September, 2025. The 50 multiple-choice questions on this practice test will assess your understanding of such topics as driving maneuvers, cargo management, emergency preparedness, and pre-trip inspections. Unlike the official test, however, this practice test comes with an automated assistant that can give you various kinds of help, including hints to gently guide you to the correct answer and an explanation of the correct answer. Plus, there’s no time limit. Take all the time you need to learn the material. If you’re not sure how to answer a question, put the practice test aside momentarily while you try to look up the correct answer in the CDL manual. You’ll learn far more by researching the correct answer to the question than by guessing it.
