If you’ve never been a commercial driver before, you must obtain a commercial learner’s permit (CLP) before you can apply for a commercial driver’s license (CDL). Your CLP will allow you to practice operating commercial motor vehicles (CMVs) while supervised by a commercial driver at least 20 years of age who has held a CDL for at least two years. In Maine, you must be at least 16 years old for a CLP. You must meet the documentation and medical requirements and pass a set of knowledge tests for the class and the type of vehicles you plan to drive. However, all aspiring commercial drivers must pass the official General Knowledge test, which covers general commercial driving theory.
The official General Knowledge test covers many commercial driving topics, including pre-trip and other vehicle inspections. Your test will likely include questions on which systems or components to check during a pre-trip inspection and how to determine whether they are performing adequately. All questions on the General Knowledge test are based on the official Maine CDL manual (Maine CDL Handbook 2025). You should study the manual, but the sheer volume of information may leave you feeling overwhelmed and wishing for additional help to pass the General Knowledge test. If so, you’ve come to the right place!

This Maine CDL Pre-Trip Inspection Practice Test is the first of several we offer. It will help you reinforce the knowledge you gained from reading the CDL manual and prepare to correctly answer the General Knowledge test questions on pre-trip inspections. Like the official knowledge test, this practice test is multiple choice. For each question, you must choose the best or most complete answer choice. Our AI Assistant can help you out. It can supply hints and explanations and answer your own questions on commercial driving.
The information you’ll learn through our Maine CDL Pre-Trip Inspection Practice Tests should also prove helpful as you practice pre-trip inspections to pass the official skills test. And it may even prove helpful in your commercial driving career when you’ll be performing actual pre-trip inspections.
Winter storms and freezing rain can make driving hazardous on numerous Maine roads. Even interstates like Interstate 95 and Interstate 295 can be greatly affected by snow and ice, which add to the accident risks posed by heavy traffic and urban congestion. Furthermore, treacherous black ice commonly occurs on I-95 during the colder months. In addition to snow and ice in winter, fog and urban congestion can present problems on U.S. Route 1 year-round. A thorough pre-trip inspection of your vehicle will help ensure it’s ready to tackle these conditions safely.
