IL CDL HazMat Practice Test 2 2025

This second free Illinois DMV commercial driver’s license (CDL) Hazardous Materials (HazMat) practice test can make learning a new skill seem as enjoyable as a “Saturday in the Park.” While we may not be talking about a picnic, you’ll definitely find the support you need to add a HazMat endorsement to your Illinois CDL. The practice test is a refreshing change from the outdated approach of traditional study guides.

From the gas in your car to the propane that fires your grill, many of the products you regularly use are considered hazardous. The federal government regulates their transportation, and you must know the correct way to label, store, and secure them. There are many advantages to obtaining a HazMat endorsement, including increased pay and more driving opportunities. However, you must develop an extensive knowledge of the rules and regulations that protect people, property, and the environment.

Our Illinois DMV CDL HazMat endorsement practice test is designed to recognize the topics you need help understanding. Along with completing an entry-level driving course and undergoing a Transportation Security Administration (TSA) background check, you must pass an official knowledge test to obtain a HazMat endorsement. You can depend on the practice test to help you correctly answer at least 80% of the 30 questions on the official knowledge test to pass. The strategy for achieving this success uses 30 questions, similar to those on the official knowledge test, to establish a baseline to begin your study.

With this Illinois DMV CDL HazMat endorsement practice test, you can watch your driving skills grow through learning reliable information and how to apply it. This approach is quite different from a study guide that merely trains you to memorize the answers to a series of questions. In comparison, the practice test allows you to demonstrate your knowledge and teaches you how to correct any errors in your thinking. If you miss a question, the practice test responds with a full explanation of the information you must know to correct it. The practice test is based on the most recent Illinois DMV CDL manual (Illinois CDL Handbook 2025) and is up to date as of December 2025. You’ll be ready to approach the official knowledge test with the skills and confidence necessary to pass it on your first try.

More and more drivers are using our series of practice tests to learn new driving skills. You’ll find practice tests for air brakes, tanker vehicles, and much more.
