Every aspiring commercial driver must learn the proper method for conducting a pre-trip inspection of their vehicle. This practice is required by federal regulation 49 CFR § 396.13 for drivers to verify the safety of the vehicle for use on public roads. Checklists are commonly used to make sure all of the vehicle systems and components, such as the tires, brakes, lights, and mirrors, are included in the inspection. Breakdowns in Dover or accidents in Wilmington can be prevented by closely examining these items. You should spend some time learning about pre-trip inspections before applying for a Delaware Commercial Learner’s Permit (CLP), which will allow you to train for a state Commercial Driver’s License (CDL). By becoming thoroughly familiar with the pre-trip inspection process, you’ll be able to perform safety measures that can save lives, protect cargo, and prevent untimely mechanical malfunctions.
While there are several requirements to meet when applying for a CLP, one of the main ones is passing the DMV CDL General Knowledge Test, which includes questions about pre-trip inspections. The official knowledge test requires you to answer 80% of the 20 questions to earn a passing grade. A firm grasp of the pre-trip inspection process will give you a great advantage in meeting this requirement. Our Delaware DMV Pre-Trip Inspection Test is an excellent resource for you to develop an intrinsic knowledge of the process. Although there are multiple on-line resources you may choose from, the practice test is designed differently to provide an optimal learning experience.

Even though study guides have been popular in preparing for tests, our Pre-Trip Inspection Practice Test offers a more effective and comprehensive method of training. The practice test is based on the most recent Delaware DMV CDL manual (Delaware CDL Handbook 2025) and is up to date as of December 2025. It includes 20 multiple-choice questions, just like the ones on the official knowledge test, to provide expert instruction on pre-trip inspections. If you get a question wrong, the practice test will provide a detailed and authoritative explanation of the correct answer. Study guides offer no additional instruction because they are designed to help you memorize the answers to the questions. This approach deprives you of complete information for conducting pre-trip inspections responsibly. The practice test equips you with the knowledge and confidence necessary to pass the official knowledge test and protect you from unexpected road hazards.
