About the South Carolina Hazmat Test
Topics Covered
- ✓Hazard classes and divisions — you need to know which class is which because SC ports and rail yards handle everything from corrosives to radioactive materials
- ✓Placarding and markings — Port of Charleston inspectors check placards before trucks leave the terminal; get it wrong and you don't move
- ✓Shipping papers and emergency response — the SC Highway Patrol uses the ERG for every hazmat incident on I-95 and I-26, and they expect you to know your papers

📘 Study Tips & State Info
When you study, don't just memorize the hazard class numbers. South Carolina examiners ask scenario-based questions. They'll say something like "You're hauling a mixed load from the Port of Charleston to Greenville. The load includes flammable liquids and corrosive solids. How do you placard the vehicle?" Know the compatibility table — that's where most people slip up.
Another thing SC examiners focus on: the 1,000-foot rule for railroad crossings. If you're carrying hazmat and you come to a railroad crossing within 1,000 feet of a grade, you have to stop. That comes up a lot. Also, know the difference between a bulk and non-bulk packaging. SC has a lot of small-quantity shippers, so they test that distinction.
Practice with our timed quiz. The real test gives you 40 minutes, but most people finish in 20-25. If you're taking the whole 40, you're overthinking. Trust your training. And don't forget the TSA fingerprinting — that's separate from this test but required to get the endorsement on your license.
The South Carolina DMV (SCDMV) handles all CDL testing. You can take the Hazmat written test at any SCDMV office that offers CDL services. Offices in Charleston, Columbia, Greenville, and North Charleston are the busiest — expect wait times and make an appointment online at scdmvonline.com. The test fee is $2.50 per endorsement, and you'll also pay a $12.50 CDL skills test fee if you're taking the road test at the same time.
Before you can take the Hazmat test, you need a current Medical Examiner's Certificate (DOT physical). You also need to pass a TSA background check (the Hazmat Threat Assessment). That's a separate process through TSA — schedule it online, pay $86.50, and get fingerprinted at a TSA enrollment center. You can't get the Hazmat endorsement on your license without the TSA clearance. SCDMV will not process your application without proof of TSA approval.
South Carolina follows FMCSA guidelines for the written test: 30 multiple-choice questions, 80% to pass. You can take the test in English or Spanish at most offices, but the CDL manual is only available in English. If you fail, you can retake it the next business day. No limit on retakes, but you pay the $2.50 each time.
About the South Carolina Hazmat Test
South Carolina's a big state for hazmat. The Port of Charleston moves more containerized cargo than almost any other East Coast port, and a lot of that cargo is hazardous. You'll see tanker trucks on I-26 every day, heading from the port up to the chemical plants in the Upstate. That's why the SC DMV takes this test seriously.
The Hazmat endorsement test covers federal rules — proper shipping names, hazard classes, placarding, loading and unloading, and what to do in a spill. But South Carolina also throws in a few state-specific wrinkles. For example, you need to know the designated hazmat routes around cities like Columbia and Greenville. The test is 30 questions, and you need 24 right to pass. That's 80%.
You'll take this test at any SCDMV office that offers CDL testing. Bring your current Medical Examiner's Certificate and your CLP. If you already have a Class A or B CDL without hazmat, you can add the endorsement by passing this written test and the background check. Don't forget the TSA fingerprinting — that's a separate process, and you need to do it before you take the skills test if you want the HME on your license.
Study the federal hazmat sections in the SC CDL manual. Pay attention to the 9 hazard classes, compatibility table, and the rules for transporting explosives and gases. South Carolina examiners love questions about proper placarding and when you can use a DANGEROUS placard instead of individual ones. They also ask about the 1,000-foot marker rule for rail crossings — that's a federal thing, but they test it here.
