About the New Hampshire Hazmat Test
Topics Covered
- ✓Placarding requirements — NH enforces strict placard placement because you'll often pass through residential areas on narrow roads; a missing placard can get you pulled over fast.
- ✓Loading and unloading procedures — especially important for propane delivery in NH's rural areas where you're backing into tight driveways on slopes.
- ✓Shipping papers — NH examiners want to know exactly where the papers need to be and how to keep them accessible during an inspection on I-89.

📘 Study Tips & State Info
NH examiners are no-nonsense. They've seen drivers blow the hazmat test because they memorized the placard numbers but couldn't tell you where to put the shipping papers. Focus on the practical stuff: when you're stopped at a weigh station in Hooksett, the inspector will ask for your papers. They need to be within arm's reach, not buried under your lunch bag. The test will ask about that.
Another thing: NH follows the federal Hazardous Materials Regulations (49 CFR) but also has state-specific rules for intrastate hauling. The NH CDL manual includes a section on state hazmat laws. Read it. Especially the part about local route restrictions — some towns like Lincoln or North Conway have ordinances that ban hazmat on certain streets. The test might ask a general question about who sets those restrictions.
Finally, practice the segregation table. NH examiners love that question. They'll give you two materials and ask if they can be loaded together. Know the table cold. And don't forget the ERG — the Emergency Response Guidebook. You don't need to memorize it, but you need to know how to use it. The test will ask what section to look in for a given UN number.
You take the Hazmat written test at a NH DMV office that offers CDL knowledge exams. The main locations are Concord (23 Hazen Drive), Manchester (1275 S. Willow St.), Portsmouth (2690 Lafayette Rd.), Nashua (30 Temple St.), and Rochester (75 Wakefield St., Suite 7). You don't need an appointment for the written test — walk-ins are accepted, but go early. The lines can get long, especially in summer.
The test fee is included in your CDL application or endorsement fee. For the hazmat endorsement itself, you'll pay a separate fee when you add it to your license. The TSA background check costs about $86.50 and you need to schedule that at a TSA enrollment center — there's one in Manchester. You'll get a Hazardous Materials Endorsement (HME) threat assessment before the DMV will issue the endorsement.
One more thing: if you let your hazmat endorsement expire for more than two years, you have to retake the written test. And if your TSA background check expires (it's good for five years), you have to reapply. Don't let that lapse — it's a hassle to redo.
About the New Hampshire Hazmat Test
New Hampshire isn't just another state when it comes to hauling hazardous materials. You've got narrow two-lane roads through the White Mountains, winter ice that makes braking a gamble, and plenty of fuel deliveries to homes and businesses. The Hazmat endorsement on your CDL isn't optional if you plan to move anything from propane tanks to gasoline — it's required by both federal law and the NH Division of Motor Vehicles.
The test covers the full federal hazmat curriculum: placarding, shipping papers, loading and unloading, and emergency response. But NH examiners also expect you to know how state-specific rules apply. For example, you need to understand that many NH towns have local ordinances about hazmat routes — and you're responsible for knowing them. You'll also face questions about winter driving with hazmat, because black ice on I-93 doesn't care about your load.
You'll take this test at one of the NH DMV offices that offer CDL written exams — Concord, Manchester, Portsmouth, Nashua, or Rochester. It's a 30-question multiple-choice test. You need 24 correct to pass (80%). You can take it with your General Knowledge test when you apply for your CLP, or later when you add the endorsement.
One thing that trips up a lot of drivers: NH requires a TSA background check and fingerprinting before you can get the hazmat endorsement on your license. That's a separate process, not part of the written test. Plan ahead — it can take weeks. Don't wait until you need the endorsement tomorrow.
