By adding a Hazardous Materials (HazMat) endorsement to your Texas commercial driver’s license, you can take advantage of numerous benefits. While the Astros measure their success with pennants, you most likely measure the success of your driving career in employment opportunities and earnings. Our Texas DMV CDL HazMat endorsement practice test uses a groundbreaking teaching method to prepare you for the challenges of earning this endorsement. The practice test will teach you the rules and regulations you must know to safely haul hazardous materials. Learning to safely transport gasoline, propane, and other materials considered hazardous will make you an attractive hire for potential employers. However, your success will greatly depend on the quality of the training you receive.
Our Texas DMV CDL HazMat endorsement practice test begins by conducting an assessment of your current knowledge level and giving you an opportunity to expand it.
Before you receive a HazMat endorsement, you must complete an entry-level driver training course, undergo a Transportation Security Administration (TSA) background check, and pass an official knowledge test. You must correctly answer at least 80% of the 30 questions on the official knowledge test to earn a passing score. The practice test is designed to give you a strategic advantage in your preparation to achieve this score. Using 30 questions similar to the ones on the official knowledge test, the practice test mirrors the actual test and identifies the information you must better understand. It’s a great starting point!

The practice test is based on the most recent Texas DMV CDL manual (Texas CDL Handbook 2026) and is up to date as of January 2026. The information from this source is accurate and helps you apply it to various driving scenarios.
