About the North Carolina Hazmat Test
Topics Covered
- ✓Placarding and labeling — NC inspectors at weigh stations on I-85 check placards first thing. Wrong placard means a ticket and an inspection.
- ✓Shipping papers and emergency response information — you carry these in the cab. NC law requires them within arm's reach.
- ✓Hazard classes and divisions — from explosives to corrosives. We see a lot of chlorine and anhydrous ammonia in eastern NC agriculture.

📘 Study Tips & State Info
Here's what I see NC drivers mess up most: the compatibility chart. You'll get a scenario like 'you're hauling nitric acid and diesel fuel' and you need to know they can't ride together. NC examiners pull from real-world cargoes we see — fertilizers, propane, chlorine, gasoline. Study the segregation table in the handbook until you can picture it.
Second tip: know your shipping papers. The test asks what information goes on them and where they're kept. In North Carolina, you keep them in the cab within arm's reach of the driver. That's not just a test question — it's the law. We also ask about Emergency Response Guidebook (ERG) — you should know how to look up a hazard class by its four-digit ID number.
Third: don't forget the details. Things like 'what do you do if a placard falls off?' or 'how far must a vehicle displaying a placard stay from an open flame?' These are easy points if you've read the handbook. The NC DMV manual has a section on hazmat — read that chapter twice. I've seen students pass after three hours of studying. You can too.
North Carolina CDL testing is handled by the N.C. Division of Motor Vehicles. You'll take the Hazmat written test at any driver license office that offers CDL testing — most do, but call ahead. Popular locations include the Raleigh office on New Bern Avenue, the Charlotte office on West WT Harris Boulevard, and the Greensboro office on East Meadowview Road. Appointments are strongly recommended; walk-ins wait hours.
You need a valid Medical Examiner's Certificate and your current CDL or CLP to take the endorsement test. The Hazmat endorsement also requires a TSA threat assessment — that's a separate process through TSA's Hazmat Endorsement Threat Assessment Program. You'll need to provide proof of that before the DMV will add the endorsement to your license. Cost: the endorsement test fee is $5 (in addition to your license fees). The TSA background check costs $86.50 as of 2025.
One more thing: North Carolina has specific hazmat route restrictions. For example, the I-40 tunnels between North Carolina and Tennessee prohibit hazardous materials. You must use I-26 or other designated routes. The DMV doesn't ask about every route on the test, but they do expect you to know that some roads and tunnels are off limits for hazmat loads. Check the NC Hazmat Route Map before you drive.
About the North Carolina Hazmat Test
I've been teaching hazmat at the North Carolina DMV for 15 years. If you're hauling anything from propane to chlorine on our roads, you need this endorsement. The test covers everything the feds require, but I'll tell you what NC examiners actually care about.
North Carolina's got it all — mountain grades on I-40 near the Tennessee line, flat coastal runs on I-95, and heavy traffic on I-85 through the Piedmont. Your hazmat load doesn't care about the scenery. You need to know how to placard, what goes where on the truck, and what to do when something goes wrong.
The test is 30 multiple-choice questions. You need 24 correct to pass — that's 80%. You get 40 minutes, which is plenty if you know the material. The NC DMV uses the same federal standards as every other state, but we've got our own quirks. For example, we have hazmat restrictions in the I-40 tunnels near the Tennessee border. You'll see questions about route restrictions like that.
This practice test pulls from the same pool of questions the DMV uses. I wrote it based on what I've seen students miss for years. Take it seriously. A hazmat endorsement means you're responsible for everyone on the road — including the folks driving past you on I-440.
