Illinois CDL HazMat Practice Test
Getting the HazMat (H) endorsement on your Illinois CDL means passing a knowledge test on hazardous materials — the Section 9 material that state CDL handbooks, including the Illinois handbook, are built on. This free diagnostic samples that material across all its topics, with instant grading and a source citation for every answer.
Before the test, first-time HazMat applicants must complete FMCSA Entry-Level Driver Training (ELDT) hazmat theory training from a provider on the Training Provider Registry, and every applicant must pass a TSA security threat assessment. Check the current Illinois CDL handbook and the Illinois Secretary of State for the latest state-specific requirements, fees, and testing details.
Original practice questions based on the official CDL handbook (Section 9) and 49 CFR. Not actual exam questions. Questions you miss are saved to your wrong-answer notebook on this device.
