If you want to get a commercial driver’s license (CDL) but have never passed the official skills test for the vehicles you plan to drive, you must first obtain a commercial learner’s permit (CLP) and hold it for at least 14 days. Your CLP will allow you to practice operating commercial motor vehicles (CMVs) while supervised by a licensed commercial driver qualified to operate that type of vehicle. Before you can be issued a CLP, you must pass the official General Knowledge test (which covers general commercial driving theory) and specialized knowledge tests that pertain to the class and the type of vehicles you plan to drive.
The General Knowledge test covers a wide range of topics in commercial driving, including pre-trip and other types of vehicle inspections. All questions on the General Knowledge test are based on the official Wisconsin CDL manual (Wisconsin CDL Handbook 2026). To prepare for pre-trip inspection questions on the knowledge test, you should study the sections in the manual dealing with this topic. However, if you’re stunned by how much you have to learn and wish you could have more help to learn it – that’s what we’re here for!

This Wisconsin CDL Pre-Trip Inspection Practice Test is the first of several we offer. By practicing answering questions about pre-trip inspections, you will absorb the material in the CDL manual much faster. Like the official knowledge test, this practice test is multiple choice. You must choose the best or most complete answer for each question. Our AI Assistant can help you. It can supply hints and answer your own questions on commercial driving. If you still miss a question, the AI Assistant will immediately tell you and explain the correct answer.
The information you’ll learn through our Wisconsin CDL Pre-Trip Inspection Practice Tests will also help you as you practice pre-trip inspections to pass the official skills test.
Several of Wisconsin’s commercial routes can be dangerous at times. You and your vehicle must be able to handle such conditions safely. For example, Interstate 94 is a major east-west commercial route – and one of the state’s most dangerous highways. Multiple factors are responsible: potentially severe winter weather (snow and ice), heavy truck traffic and frequent urban congestion in the Milwaukee area, and several off-ramps close together, leading to driver confusion and a higher risk of accidents. However, a comprehensive pre-trip inspection of your vehicle’s safety-critical systems will help ensure it’s ready to tackle these difficult conditions.
