Free Virginia CDL HazMat Endorsement Practice Test 2026

You’re here, so you must be considering adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL). That’s an excellent way to add marketability and a potential increase in earnings to your career. The Hazmat endorsement permits drivers to transport materials that the U.S. government has deemed hazardous. If you don’t have the endorsement, you are most assuredly ineligible to transport that entire class of cargo! Once endorsed, the materials available for transport range from explosives and certain types of fuel to industrial chemicals, radioactive materials and infectious substances. But know this: the most important objective of this endorsement process is to ensure your safety and protect the people and environment in your driving area.

The minimum age for the Hazmat endorsement in Virginia is 21. To add this endorsement, you’ll need to pass a Transportation Security Administration (TSA) fingerprinting and background check and the DMV knowledge test. The knowledge test covers federal regulations, substance handling, and a host of other topics. Virginia’s knowledge test is made up of 30 questions and must be passed with a score of at least 80% (24 out of 30 answers must be correct) (Virginia CDL Handbook 2026).
