Earning your Idaho CDL requires successfully passing the Idaho CDL General Knowledge Exam as well as the CDL Pre-Trip Inspection Test. The Idaho CDL General Knowledge Exam includes questions specific to pre-trip inspection materials. Our Idaho CDL Pre-Trip Inspection Practice Tests are specifically designed to cover all necessary topics. Without passing this knowledge exam, you will not even be able to obtain a Commercial Learner’s Permit (CLP), much less the CDL necessary for independent commercial driving. Additionally, if you fail the knowledge exam, you’ll need to wait at least one day for a retest, and there may be an additional fee. Our practice tests provide the tools you need to pass the knowledge exam on your first attempt. As a bonus, this preparation will also help you with your hands-on Pre-Trip Inspection test, where you must accurately assess your vehicle’s condition. According to federal regulations 49 CFR § 392.7 and 49 CFR § 396.13, this inspection is required before hitting the road and is one of three skills tests that must be passed to receive a full CDL—alongside the basic control skills test and road test.
For both the Idaho CDL General Knowledge Exam and the CDL Pre-Trip Inspection Test, you’ll need to prove your familiarity with, and ability to thoroughly check, the vehicle’s engine compartment, cab controls, lights, tires, brakes, suspension, and cargo securement. In the Idaho Seven-Step Inspection Method, you must be able to physically point to, touch, and name each component during your pre-trip inspection test and explain why it is being inspected during the pre-trip test. Your examiner must attest that you can determine whether all parts are in good working condition and free of defects.
This practice test is based on the most recent Idaho CDL manual (Idaho CDL Handbook 2025) and contains 20 multiple-choice questions to assess your knowledge of pre-trip inspections. Unlike less effective study guides, our approach includes detailed explanations after each response you provide, which speeds learning and helps you pass the official knowledge test on your first attempt.
Be sure to check out our different practice tests to help fully prepare you for other parts of your upcoming exams.
