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 April 2025

Until you possess a Idaho Commercial Learner’s Permit (CLP), you will not be able to receive hands-on training to become a commercial driver. An important skill you must learn is the proper way to conduct a thorough pre-trip inspection of your vehicle. You will likely use a checklist to work your way through inspecting the various systems and components of the vehicle, such as the brakes, headlights, tires, and windshield wipers, to verify their safe operation. You are required to hold a CLP before you may apply for a Idaho Commercial Driver’s License (CDL), and you must demonstrate your knowledge of pre-trip inspections. These trip inspections are required by federal regulation 49 CFR § 396.13 to verify your vehicle is safe for road use. An accident in Moscow or a breakdown in Boise could be a costly way to spend your day.

Our Idaho {government-agency] CDL Pre-Trip Inspection Practice Test is expertly designed to teach you the nuts and bolts of this process. The practice test will help you understand the items needing inspection and how they might become problematic. It contains reliable information to help you stay safe while transporting cargo over short or long distances. The DMV CDL General Knowledge Test requires you to answer 80% of the 20 questions correctly to earn a passing grade. You can depend on the practice test to enhance and increase your knowledge of the pre-trip inspection process. Using the practice test, you can confidently answer any question about pre-trip inspections that gets you closer to passing the official knowledge test.

Unlike many other on-line resources, the CDL Pre-Trip Inspection Practice Test is interactive and designed to provide feedback on your answers. The practice test offers you the most relevant and authoritative information available. It is based on the most recent Idaho DMV CDL driver’s manual (Idaho CDL Handbook 2025) and up to date as of April 2025. It includes 20 multiple-choice questions, similar to those on the official knowledge test, to assess your understanding of the pre-trip inspection process. If you submit an incorrect answer, the practice test will provide a detailed explanation of the correct one. You won’t find such a feature in a study guide. Study guides help you memorize the answers to the questions, but you would need to do your own research to clear up any misconceptions. You can use the practice test to elevate your knowledge of pre-trip inspections and help keep you safe in your daily travels.

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.
