You will learn about pre-trip inspections as a part of your driver’s training for a Oregon Commercial Learner’s Permit (CLP). Federal regulation 49 CFR § 396.13 requires commercial drivers to verify the operational safety of their vehicles before driving on public roads. If you’re traveling through Portland, especially during rush hour, you don’t want a smash-up or blown hose to ruin your day. A checklist of the crucial systems and components of your vehicle, such as the tires, brakes, mirrors, and engine, will ensure you complete a thorough inspection.
Before applying for a Oregon Commercial Driver’s License, you must earn a CLP, which means meeting several requirements. One of the key requirements you must meet is to pass the DMV CDL General Knowledge Test, which includes questions about pre-trip inspections. Our Oregon DMV Pre-Trip Inspection Practice Test helps you thoroughly learn the process in a simulated testing environment. The official knowledge test requires you to answer 80% of the 20 questions correctly to receive a passing score. The practice test will help you improve your test score by providing expert instruction to answer questions about this safety measure.
Our CDL Pre-Trip Inspection practice test allows you to assess your current knowledge of pre-trip inspections with reliable and authoritative information. It contains 20 multiple-choice questions, similar to those on the official knowledge test, to more effectively manage your study time. The practice test is more effective and time-efficient than any study guide because it is interactive. If you get a question wrong, the practice test will provide a detailed explanation of the correct answer. This information is taken directly from the Oregon DMV CDL driver’s manual (Oregon CDL Handbook 2025) and is up to date as of December 2025. In comparison, a study guide offers no interactive feedback on wrong answers. You will either be left to your own interpretation or forced to consult additional sources. The practice test gives you access to first-rate learning in its most convenient form.
