Free NJ CDL Pre-Trip Inspection Practice Exam 2025

If you haven’t been a commercial driver before, you must obtain a commercial learner’s permit (CLP) before you may apply for a commercial driver’s license (CDL). Your CLP will allow you to practice operating commercial motor vehicles (CMVs) while supervised by a CDL holder. The requirements for a CLP include passing a set of official knowledge tests for the class and the type of vehicles you plan to drive. However, one knowledge test is required, regardless of which vehicles you plan to drive: the General Knowledge test, which covers general commercial driving theory.

The official General Knowledge test covers many topics, such as basic vehicle control, hazard perception, cargo handling, accident procedures, and vehicle inspections, including pre-trip inspections. Your test will likely include some questions on pre-trip inspections, including how to tell if your CMV’s systems and components are functioning correctly and how to detect defects or faults. Federal regulation 49 CFR § 392.7 lists the most critical items to inspect. You must be sure that all these systems are in good working order before you drive the vehicle: brakes, coupling devices (if so equipped), emergency equipment, horn, lights and reflectors, mirrors, steering, tires, wheels and rims, and windshield wipers.

All questions on the General Knowledge test are based on the official New Jersey CDL manual (New Jersey CDL Handbook 2025). To prepare for this test, you should start by studying this CDL manual. But don’t be tempted to stop there. There’s a large amount of complex information to absorb and memorize. You can reinforce your newfound knowledge by practicing how to answer test questions about it. That’s where we come in.

This New Jersey CDL Pre-Trip Inspection Practice Test will help you master the material on pre-trip inspections and ace the pre-trip inspection questions on the official General Knowledge test. Like the official test, this practice test is multiple choice. Each question comes with several answer options. You must choose the best or most complete answer. Our AI assistant can help you with any practice question. It 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 tell you and provide an explanation of the correct answer.

Unlike the official General Knowledge test, this practice test isn’t timed. Take your time and learn as much as you can. If you want, use the practice test as an open-book test and look things up in the CDL manual as you proceed.
