About the HazMat Test in Maine

The HazMat endorsement test is required in Maine for drivers who transport hazardous materials. It covers placarding, labeling, loading procedures, emergency response, and compliance with federal hazmat regulations. A TSA background check is also required.

The HazMat test is part of the CDL written exam administered by the Maine Department of Motor Vehicles. You must pass this test along with the other required written tests to receive your Commercial Learner's Permit (CLP) in Maine.

Our practice questions are built from the official Maine CDL handbook and federal FMCSA regulations. Each question includes a detailed explanation to help you understand the material, not just memorize answers.

How to add the HazMat endorsement in Maine

Check you qualify: the H endorsement requires you to be 21, to meet the FMCSR Part 391 physical qualifications and hold a valid medical card, and to pass a TSA fingerprint and background check. Source
Complete Entry-Level Driver Training first if this is your first hazardous materials endorsement — drivers who already held an H endorsement issued before February 7, 2022 are exempt. Source
Pay the $20 endorsement examination fee and pass the hazardous materials written examination at your scheduled BMV appointment. Source
Only after you pass the hazmat written examination do you start the TSA fingerprint and background records check — Maine runs the knowledge test first. Source
Wait for TSA clearance: Maine may not issue a CDL carrying a hazmat endorsement until the security threat assessment is complete and cleared. Source
At every renewal, file the renewal application at least 30 days before the licence expires and retake the hazardous materials written test — Maine statute requires the re-examination to keep the endorsement. Source

Maine CDL questions

How do I book the Maine CDL knowledge and skills tests?: You do not walk in. Mail the completed CDL application with the fees to the Bureau of Motor Vehicles, CDL Examination Section, State House Station 29, Augusta, and the main office schedules you — an appointment notice comes back with the place, date and time for the knowledge test. After you pass, you get a skills test request card, which you mail back to Augusta to be scheduled for the skills and road test. Cancel a test less than 48 hours ahead and an extra $70 is charged before you can be rescheduled. Branch offices are open Monday–Friday from 8 a.m. and take online appointments for other business. Source
What does Maine require for a hazmat (H) endorsement?: You must be 21, meet the FMCSR Part 391 physical qualifications and hold a valid medical card. Maine runs the written test first: once you pass the hazardous materials written examination ($20 endorsement fee) you begin the TSA fingerprint and background records check, and no CDL with a hazmat endorsement may be issued until TSA clears you. Renewals must be filed at least 30 days before the licence expires, and 29-A M.R.S. §1253(3) requires you to retake the hazmat written test at every renewal to keep the endorsement. Source
Can I add endorsements to my Maine commercial learner’s permit?: No. The Maine CDL Manual is explicit that endorsements can only be added to a Commercial Driver’s License — if you do not yet hold a CDL, the endorsement is not awarded until you do. Maine grants the N, H, X and T endorsements on the knowledge examination alone; P and S also require the skills and road test. Source
How old do you have to be to get a CDL in Maine?: The Maine CDL Manual sets 16 as the minimum age to operate a commercial motor vehicle and 21 to drive a bus or carry hazardous materials; the application form repeats 21 for the H, P and S endorsements, and adds that a school bus applicant must have held a valid licence for one full year. Federal rules separately limit interstate driving to drivers 21 and over, which is why an intrastate-only CDL carries the Maine “K” restriction. Source
