Federal regulation 49 CFR § 396.13 requires commercial drivers to complete a pre-trip inspection to verify the safety of their vehicles before driving them on public roads. By using a checklist to verify the safety of the vehicles, commercial drivers can confirm the safety-critical systems and components of their vehicle, such as the brakes, taillights, windshield, and tires, meet safety standards. A thorough pre-trip inspection may prevent accidents and untimely mechanical malfunctions, saving lives, protecting cargo, and avoiding lost work time. The Turner Turnpike is not a place you want to have a costly mishap. Considering the potential consequences, it would be wise for you to take a deep dive into the pre-trip inspection process before applying for your Oklahoma Commercial Learner’s Permit (CLP).
Before you may apply for a Oklahoma Commercial Driver’s License (CDL), you need to develop your driving skills and habits, including pre-trip inspections, with a CLP. While there are a few additional requirements to obtain a CLP, one of the major ones is passing the DPS CDL General Knowledge Test. You can expect to see numerous questions about pre-trip inspections on the official knowledge test. To earn a passing grade on the official knowledge test, you must answer 80% of the 20 questions correctly. Your understanding of pre-trip inspections will help pave the way for you to pass the official knowledge test. Our Oklahoma DPS Pre-Trip Inspection Practice Test will teach you the details of this safety measure in a simulated testing environment.

While you may find other on-line resources, such as study guides, this CDL Pre-Trip Inspection Practice Test provides the most comprehensive and authoritative information for conducting the process. The practice is interactive and provides you with feedback to fill your knowledge gaps. It helps you establish a solid knowledge base on which to build your driving skills. While study guides teach you to memorize the answers to the questions, the practice test contains 20 multiple-choice questions to assess your knowledge of pre-trip inspections. If you submit an incorrect answer, the practice test will provide you with a detailed explanation of the correct one. You can rely on this information because it is based on the most recent Oklahoma DPS CDL driver’s manual (Oklahoma CDL Handbook 2025) and up to date as of December 2025. Pre-trip inspections are too important for you to settle for anything less than a resource that increases your knowledge and confidence in performing them. The practice test will get you started toward safe travels.
