📘 Study Tips & State Info
South Dakota examiners love to ask about shipping papers and emergency response information. They want you to know exactly where the papers are supposed to be — on the driver's seat or within arm's reach. Don't just memorize the order; understand why a trooper needs to grab them fast during a roadside inspection on a cold February morning.
Focus on placarding rules for common SD hazmat loads. Anhydrous ammonia (UN1005) and propane (UN1075) show up all the time. Know the difference between a bulk container and a non-bulk container. The test will throw in a scenario about a 500-gallon propane tank on a flatbed — is that placarded or not? You need to know.
Use our practice test to drill the numbers and classes. The real test has a few questions that trip people up, like 'Which way do you turn the shut-off valve on a chlorine tank?' or 'How far from the vehicle must your emergency warning devices be placed?' Run through the practice test until you're getting at least 27 out of 30 right. That's your safety margin.
The South Dakota DMV handles all CDL testing. You can take the Hazmat written test at any full-service Driver Licensing office. Major locations include Pierre (state capital), Sioux Falls (I-29 corridor), Rapid City (I-90 west), Aberdeen, and Watertown. Appointments are strongly recommended — walk-ins can wait hours, especially during harvest season when everyone's getting their CDL renewed.
You'll need to bring your valid CDL permit, proof of Social Security number, and a current Medical Examiner's Certificate (DOT physical). The Hazmat endorsement test fee is $20 on top of your CDL license fee. After you pass the written test, you must complete a TSA background check (Hazmat Endorsement Threat Assessment). That process takes 4 to 6 weeks and costs about $86. You can't get the endorsement on your license until the TSA clears you.
South Dakota doesn't have a separate hazmat skills test — you just take the written knowledge test. But you do have to pass the General Knowledge test first. If you already have your CDL, you can add the Hazmat endorsement by taking only the Hazmat test and submitting the TSA clearance.
About the South Dakota Hazmat Test
The Hazmat endorsement is a federal requirement, but South Dakota adds its own wrinkles. You're not just memorizing placard codes — you need to know how to handle hazardous materials on long, empty stretches of I-90 through the Badlands and across the Missouri River. Winter storms can shut down roads for hours, and your load doesn't care about the weather.
South Dakota's economy runs on agriculture, ethanol, and fuel distribution. That means you'll see tankers full of anhydrous ammonia, diesel, and gasoline on every highway. The Hazmat test covers everything from proper shipping papers to emergency response procedures. You need to know what to do when a valve fails near a water source like the Big Sioux River.
The test is 30 multiple-choice questions. You have 40 minutes. Passing is 80% — that's 24 correct out of 30. The South Dakota DMV administers it at all CDL testing locations, including Pierre, Sioux Falls, and Rapid City. You'll also need a TSA background check before you can get the endorsement on your license.
Our practice test mirrors the actual South Dakota exam. We pull questions straight from the SD CDL manual. Take it until you're scoring 90% or better, and you'll walk into the DMV confident.
