HAZARDOUS MATERIALS
CDL Exam (Timed)

This is a timed exam and is very similar to the official state CDL written HAZMAT endorsement exam. Each exam is unique, randomly generated from the master source of CDL questions.

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.
