IL CDL Pre-Trip Inspection Practice Test 2025

Your career as a commercial driver begins with your earning a Commercial Learner’s Permit (CLP) and knowing the safe operation of the systems and components in a commercial motor vehicle (CMV). Federal regulation 49 CFR § 396.13 requires drivers to verify all these features are working properly before putting their vehicle on public roads. By using a checklist to conduct your inspection, you can be sure that items such as the engine, tires, brakes, and windshield wipers are working properly. These inspections help keep your cargo, fellow motorists, and yourself out of harm’s way. The Prairie State can offer some adverse driving conditions due to inclement weather and heavily congested traffic along certain roadways, such as Interstate 57. However, you can ride easy when knowing your vehicle is operating in a safe mode.

Among several requirements for you to receive a CLP, you must pass the official DMV Commercial Driver’s License (CDL) General Knowledge Test, which will include questions about pre-trip inspections. Additionally, for your CDL skills test, you must perform a pre-trip inspection of a vehicle in front of an examiner. You must answer at least 80% of the 20 questions correctly to pass the General Knowledge test. Since this requirement doesn’t leave much room for error, our Illinois DMV CDL Pre-Trip Inspection Practice Test leaves no stone unturned in preparing you to answer questions about the process. It uses 20 questions just like the ones on the official knowledge test to advance your understanding of pre-trip inspections. Compared with other on-line resources, the practice test undoubtedly offers the most effective preparation available.
