ID CDL Pre-Trip Inspection Practice Test 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
Based on 2025 ID commercial driver's license manual
Triple-checked for accuracy
Updated for March 2025

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.

At Driving-Tests.org, we understand the importance of reliable and accurate practice tests to help you prepare for your DMV exam. That's why we've developed a meticulous process to create and continually update our practice questions, ensuring they reflect the most current driving laws and regulations.

Here's an inside look at how we maintain the highest quality in our practice tests.

Content Creation and Verification Process

Alignment with Official Manuals:
Every question we develop is based on the most recent version of each state's official driving manual. Our team regularly monitors each state DMV's website for the latest updates to ensure our practice tests are always aligned with the most current information.
Community Feedback Integration:
We leverage feedback from our vast community of users to understand which topics are most frequently tested. This helps us focus on the areas that are most relevant and beneficial for your preparation.
Expert Content Creation:
Our in-house editor, Steven, who has extensive experience in driver education, crafts each question with precision. He conducts a thorough review of each question against the official manuals to ensure accuracy.
Rigorous Review Process:
Once Steven has finalized a set of questions, our team conducts a joint review session. This second level of scrutiny involves content accuracy, proofreading, and fact-checking to eliminate any errors.
User Feedback Mechanism:
After a question goes live on our site, we keep the lines of communication open. Each question features a feedback button, inviting users to report any issues or errors. This continuous feedback loop allows us to address and rectify any concerns promptly.
Responsive Updates:
In line with our commitment to accuracy, we quickly update our practice questions to reflect any changes in the DMV manuals. Additionally, we update the free electronic copy of the state's driver's license manuals on our site, typically within a few days after the DMV publishes them.

Our thorough quality control process ensures that you have access to practice tests that are as accurate and up-to-date as possible. We believe in the power of well-prepared drivers and are dedicated to providing you with the best study tools to help you succeed on your DMV exam.
