CA CDL HazMat Practice Test 2 2025

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
  • Based on 2025 CA commercial driver's license manual
  • Triple-checked for accuracy
  • Updated for September 2025

If you benefited from the first one, this second California DMV CDL Hazardous Materials (HazMat) endorsement practice test will further enhance your skills. HazMat drivers must exhibit exceptional knowledge of the rules and regulations that apply to their cargoes. The practice test is part of our free California DMV study guide, which provides comprehensive instruction in the required practices for transporting hazardous materials. Gasoline, acids, and explosives are examples of cargo included in this classification. As such, these materials must be properly labeled, stored, and documented to be in compliance with federal transportation requirements. There are many iconic landmarks to see along the Sunset Strip, but you wouldn’t want to claim an infamous place in its history by causing a hazardous materials incident.

Our California DMV CDL HazMat endorsement practice test gives you a decisive advantage in effectively learning the responsibilities of drivers handling these materials. Besides 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. The practice test contains 30 questions, similar to those on the official knowledge test, to identify your specific learning obstacles and prepare you to overcome them. Use the results to develop a study plan for correctly answering at least 80% of the 30 questions on the official knowledge test required to pass. It’s the fast track to achieving your success!

This California DMV CDL HazMat endorsement practice test offers a groundbreaking approach using reliable information to expand your knowledge. Traditional study methods typically limit you to learning surface knowledge. The practice test gives you a real-time assessment of your proficiency and directs you to the information you should further study. If you get a question wrong, the practice test provides a detailed explanation of the correct answer. You can trust the explanation provided because the practice test is based on the most recent California DMV CDL manual (California CDL Handbook 2025) and is up to date as of September 2025. This information contributes to helping you understand your most difficult topics, boosting your confidence in applying it to your driving practices, and increasing your chances of passing the official knowledge test on your first try.

Besides the CDL HazMat practice test, drivers can depend on our other practice tests to train for better career opportunities. Whether getting your foot in the door with our CDL permit practice test or learning to use air brakes, our practice tests outperform any other on-line resource you may consider using.
