Interested in becoming a licensed commercial driver for the first time? Then you’ve got a lot of study and practice ahead of you. But stay undaunted. After you get your commercial driver’s license (CDL) and begin your new career in commercial driving, you’ll see that all that effort was well worth it!
Before you may obtain a CDL, you must obtain a commercial learner’s permit (CLP) and hold it for at least two weeks. This permit will allow you to practice operating commercial motor vehicles (CMVs) while supervised by a CDL holder. There are documentation, medical, and knowledge requirements for a CLP. The knowledge requirement involves passing a set of knowledge tests for the class and type of vehicles you plan to drive. At minimum, you must pass the official General Knowledge test, which covers general commercial driving theory.
The official General Knowledge test covers many commercial driving topics, including pre-trip inspections. Questions on pre-trip inspections include defects or faults to look for in a CMV’s systems and components. All questions on the General Knowledge test are based on the official Indiana CDL manual (Indiana CDL Handbook 2025). You should study the manual, but it’s more of a reference than a study aid. If you would like additional help to prepare for the test questions on pre-trip inspections, rest assured we have just what you’re looking for!
This Indiana CDL Pre-Trip Inspection Practice Test will help you learn how to correctly answer test questions on pre-trip inspections. 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 rephrase the question, 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.
The information you’ll learn through our pre-trip practice tests won’t just help you pass the General Knowledge test. It will also prove helpful as you prepare for the official skills test for a CDL. One of the three parts of this test is a pre-trip inspection test, in which you’ll conduct a pre-trip inspection before a test examiner.
