Free AZ CDL Pre-Trip Inspection Practice Exam 2025
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 AZ commercial driver's license manual
- Triple-checked for accuracy
- Updated for March 2025
If you haven’t been a commercial driver before, you must obtain a commercial learner’s permit (CLP) before you can become qualified to obtain a commercial driver’s license (CDL). The CLP will allow you to practice operating commercial motor vehicles (CMVs) while supervised by a CDL holder. A crucial requirement for obtaining a CLP is to pass a set of knowledge tests for the class and type of vehicles you plan to drive. Regardless of the vehicles, however, all aspiring commercial drivers must pass the official General Knowledge test, which covers general commercial driving theory.
The official General Knowledge test covers a wide variety of commercial driving topics, including pre-trip inspections. (Federal regulations require the driver to be satisfied their vehicle is safe before driving it.) You will likely find some questions on pre-trip inspections, including defects or faults to look for in the vehicle’s systems and components. All questions on the General Knowledge test are based on the official Arizona CDL manual (Arizona CDL Handbook 2025). You should study the manual, but many drivers have found it hard to master commercial driving theory from the manual alone. If you feel you need more to learn the theory of pre-trip inspections, we can help.
This Arizona CDL Pre-Trip Inspection Practice Test is a great way to learn how to correctly answer the questions on pre-trip inspections on the General Knowledge test. Like the official knowledge test, this practice test is multiple choice. Each question comes with several answer options. You must choose the best or most complete answer. You can also get help from our AI assistant on any question. At your request, the AI assistant can explain the question in more depth, supply a hint, or answer your own questions about commercial driving theory. If you still miss the question, the AI assistant will immediately let you know and provide an explanation of the correct answer. With immediate feedback after every question, you won’t need to wait until the end of the test to know the correct answers.
The information you’ll learn through our pre-trip practice tests will do more than help you pass the General Knowledge test. It will also prove useful as you practice pre-trip inspections to pass the official skills test, which includes a test of your ability to conduct a proper pre-trip inspection.
