Drivers of combination trucks (such as semi-trucks and tractor-trailers) should be in high demand in several of Wisconsin’s key economic sectors. Wisconsin is a leading agricultural state, especially in the production of cheese, butter, and milk, creating a demand for truckers to transport dairy products and other agricultural products. The state also has an important lumber industry and leads the nation in the production of paper, creating a demand for truckers to transport logs, lumber, and paper products. Besides paper production, Wisconsin’s industrial sector includes beer brewing, commercial food processing, and the production of machinery. Truckers transport raw materials to these industries and then transport their finished products.
Major trucking routes include Interstates 39, 90, and 94; U.S. Routes 41 and 51; and State Highway 29.
To legally drive commercial motor vehicles (CMVs), you must obtain a Commercial Driver’s License (CDL). To do this, you must meet a series of requirements, which include passing a physical examination, passing the official General Knowledge test on commercial driving theory, and passing the official skills test on safe operation of a CMV.

To be allowed to drive combination vehicles, you must also pass the official Combination Vehicles knowledge test on the theory of operating combination vehicles. You’ve probably started studying the official Wisconsin Commercial Driver’s License Manual (Wisconsin CDL Handbook 2025), especially Chapter 6 on combination vehicles. This 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 this study guide. If you’re having the same problem, we have some additional study tools to offer you that may help.
For instance, this free Wisconsin CDL Combination practice test, one of several we offer, will test your understanding of some of the information on combination vehicles presented in the official CDL manual. And it’s up to date as of December 2025. The 25 multiple-choice questions and answers on this practice test will assess your understanding of such topics as combination braking systems, combination driving techniques, coupling and uncoupling, and pre-trip inspections. Unlike the official knowledge test, however, this practice test comes with an automated assistant that can give you various kinds of help, including hints of 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. While you’re taking the practice test, pause the test to look up the answer to a puzzling question in the CDL manual if you wish.
