One of the most important skills you must learn before applying for your Mississippi Commercial Learner’s Permit (CLP) is how to properly conduct a pre-trip inspection. As required by federal regulation 49 CFR § 396.13, commercial drivers must verify the safety of their vehicles before driving them on public roads. Pre-trip inspections prevent accidents and help you avoid unexpected mechanical malfunctions while traveling. You should use a checklist that includes your vehicle’s main systems and components, a defect in which could jeopardize your safety or leave you stuck in an unfortunate predicament on I-55 in Jackson. Taking the time to inspect such items as your tires, brakes, battery, and windshield wipers can effectively prepare you to avoid malfunctions that lead to accidents and breakdowns.
Although you must satisfy a few requirements to earn a CLP, you will need to exhibit a firm grasp of pre-trip inspections as part of the DMV Commercial Driver’s License (CDL) General Knowledge Test. You must answer 80% of the 20 questions correctly, and some of them will pertain to pre-trip inspections. If you can answer the questions on this topic correctly, it will get you closer to earning a passing score and add to the skill set needed to obtain a CDL. Our Mississippi DMV CDL Pre-Trip Inspection Practice Test emphasizes the details involved in conducting this important safety procedure. You will find it more engaging and informative than any other on-line resource. By providing a simulated testing environment, the practice test mimics the official testing experience and lets you get a sense of what to expect. You will feel more at ease with the official knowledge test questions as you study with the practice test.

This CDL Pre-Trip Inspection Practice Test is designed to provide the most authoritative information available to support your learning potential. It is based on the most recent Mississippi DMV CDL driver’s manual (Mississippi CDL Handbook 2025) and up to date as of December 2025. The practice test contains 20 multiple-choice questions to assess your current level of pre-trip inspections. While study guides may help you assess your knowledge, they fail to provide information to help you correct the answers you may get wrong. In comparison, when you submit an incorrect answer on the practice test, you will receive a detailed explanation of the correct one. This information is useful in helping you learn the information that you don’t already know or clearly understand. You will be equipped with the logic behind the answer and be able to connect it to the question. You can rely on our Pre-Trip Inspection Practice Tests to teach you what you should know about staying safe before your wheels start rolling.
