WA CDL Pre-Trip Inspection Practice Test 2025

To obtain a Commercial Learner’s Permit (CLP) and later a Commercial Driver’s License (CDL), you must pass the Washington CDL General Knowledge Exam. The General Knowledge Exam includes questions about pre-trip inspections. After holding your CLP for at least 14 days, you must pass the Washington Pre-Trip Inspection Test and the other two parts of the three-part CDL skills exam to receive your CDL. This test determines whether drivers can properly identify and check critical vehicle components to prevent breakdowns and accidents. Our Washington CDL Pre-Trip Inspection Practice Tests help you fully prepare for this section of the knowledge exam by covering all necessary topics related to pre-trip inspections.

There are three parts to the skills test that must be passed for your CDL: the federally mandated pre-trip inspection test (regulations 49 CFR § 392.7 and 49 CFR § 396.13), the basic control skills test, and the road test. In Washington, if you fail one of the three sections of the skills test, you only need to retake the failed section, as you will receive credit for any segment passed. Also, in Washington, CDL skills test results are valid for six months. If you don’t complete all CDL requirements within this time, you must restart the process​ (and still adhere to the 365-day CLP validity period).

It’s important to note that in Washington, the pre-trip inspection must be conducted in English (no interpreters are allowed). During the pre-trip inspection part of the Skills Test, you must physically point to, touch, and name each component and explain why it is being inspected. We recommend you memorize the structured inspection method for both the Washington CDL General Knowledge Exam and the CDL Pre-Trip Inspection Test. This process includes thoroughly checking the vehicle’s engine compartment, cab controls, lights, tires, brakes, suspension, and cargo securement.

Our practice test is based on the most recent Washington CDL manual (Washington CDL Handbook 2025) and contains 20 multiple-choice questions to assess your knowledge of pre-trip inspections. All your responses elicit detailed explanations, speeding the learning process and ensuring you pass the official knowledge test on your first attempt.

We also have different practice tests to help you prepare for other parts of your upcoming exams. Please give them a try!
