Practice CDL Test 4

This CDL Hazardous Materials test will prepare you to pass EVERY state’s DMV HAZMAT exam. You must have a commercial driver license (CDL) with a hazardous materials endorsement before you drive any size vehicle that is used to transport hazardous materials as defined in 49 CFR 383.5. You must pass a written test about the regulations and requirements to get this endorsement. On the official DMV written exam, you must get at least 80% to pass.

The questions on every state Commercial Driver’s License (CDL) official exam are taken directly from that state’s CDL manual. All CDL manuals are based on FMCSA (FEDERAL) regulations, which do NOT change from state to state. Likewise, our practice tests are based on the information in your state CDL manual.
