About the New Jersey Hazmat Test
Topics Covered
- ✓Placarding and labeling – NJ's industrial ports mean you'll see a mix of hazard classes daily, and the wrong placard can shut down a whole terminal.
- ✓Shipping papers and emergency response – NJDMV examiners want you to know exactly where those papers go and what you do if something leaks on I-95.
- ✓Load segregation and compatibility – You can't just stack anything together. NJ's tight loading docks at places like Port Newark make this a real headache.

📘 Study Tips & State Info
NJ DMV examiners are sticklers for placard placement. They'll ask which side of the vehicle gets the placard, how many you need, and what happens if a placard falls off. Don't just memorize the table — think about a tanker sitting at a loading rack in Linden. Practice visualizing the whole vehicle.
Another thing they hammer: tunnel restrictions. The Lincoln Tunnel bans all hazmat except for some small exceptions. The Holland Tunnel allows limited quantities. You need to know the difference. The test will throw you a scenario like 'You're hauling 500 gallons of diesel and need to get from Jersey City to Manhattan.' What do you do? Know the tunnel rules cold.
Finally, don't skip the emergency response section. NJ examiners love asking what you do first in a spill — and it's not calling 911. It's protecting yourself and others, then notifying the carrier. Use the NJ CDL manual, but also look up the actual NJ hazmat route map online. It'll help those rules stick.
The New Jersey Motor Vehicle Commission (MVC) handles all CDL testing. You'll take the Hazmat written test at a MVC agency that offers CDL services. Major locations include Trenton, Rahway, Lodi, and Eatontown. You need an appointment — walk-ins aren't guaranteed. Bring your current CDL permit, proof of citizenship or lawful status, and a valid Medical Examiner's Certificate.
The Hazmat endorsement also requires a TSA background check (Hazmat Threat Assessment). You'll need to schedule that separately through TSA's website or at an enrollment center. The fee is about $86.50 as of 2025. Your fingerprints are taken, and the process takes a few weeks. Don't wait until the last minute.
NJ charges a fee for each endorsement added to your CDL — currently $6 per endorsement. The written test itself is included in the general CDL test fee. If you fail, you can retake it the same day if time allows, but you'll pay the test fee again. Study hard the first time.
About the New Jersey Hazmat Test
New Jersey moves more hazardous materials than most states. Think about it — the Port of Newark and Elizabeth handles thousands of containers with chemicals, fuels, and compressed gases every day. You've got refineries in Linden and Paulsboro, chemical plants along the Delaware River, and tanker trucks running the Turnpike and I-78 constantly. If you're driving hazmat in NJ, you're not in some rural backroad. You're in the thick of it.
The Hazmat endorsement lets you haul any material the DOT classifies as hazardous. That includes explosives, flammables, corrosives, and radioactive stuff. The written test is 30 questions, and you need 24 right to pass — that's 80%. NJ follows federal rules, but the examiners here pay extra attention to placarding and tunnel restrictions because those are everyday issues on our roads.
You'll also need a TSA background check before you can get the endorsement on your license. The test itself covers everything from shipping papers and emergency response to loading and unloading. Don't walk in blind. Know the rules, especially the ones that keep you alive when you're hauling propane through the Lincoln Tunnel.
