A proper pre-trip inspection should never be rushed. When done correctly, it can take up to one hour. During CDL skills tests, many applicants lose points because they miss components, failing to understand the importance of this procedure. Furthermore, they must achieve a perfect score on checking the braking system. Failing to correctly perform even one of the required brake tests results in an automatic failure of the pre-trip inspection test.
In Minnesota, the Department of Public Safety (DVS) publishes the official Commercial Driver’s Manual (Minnesota CDL Handbook 2026). This is the primary study resource for aspiring commercial drivers, but its contents often confuse beginners. The complex wording can easily overwhelm those who are not familiar with commercial driving theory, making it difficult to understand this subject. As a solution, we have developed a series of practice tests that will help you become a safe and responsible commercial driver.
Now you’re about to train with our second Minnesota CDL Pre-Trip Inspection Practice Test. It includes questions that mirror the official General Knowledge Exam format and wording. Each question has multiple answer choices, but only one is correct. Always read each question at least twice. This helps you fully understand what is being asked. If a difficult question confuses you, don’t hesitate to ask “Officer Frank” for help. This automated assistant can rephrase questions, provide real-life examples, and nudge you in the right direction with helpful hints.
