Free South Dakota CDL HazMat Practice Test 2025
From the desert landscapes to the mountain ranges and high plateaus, you’re probably already accustomed to the challenges of the Rocky Mountains and the Sangre de Cristo Mountains as well as the extreme summer and winter weather of South Dakota. Adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL) is an excellent way to increase marketability and potentially increase earnings. The Hazmat endorsement permits drivers, who would otherwise be forbidden, to transport materials that the U.S. government has deemed hazardous. Once you have the endorsement, the materials available for transport range from explosives and certain types of fuel to industrial chemicals, radioactive materials and infectious substances.
The minimum age for the Hazmat endorsement in the Land of Enchantment is 21. You’ll need to pass a Transportation Security Administration (TSA) fingerprinting and background check and the DMV knowledge test. The knowledge test covers federal regulations, substance handling, and a wide range of other topics. South Dakota’s knowledge test is made up of 30 questions and must be passed with a score of at least 80% (24 out of 30 answers must be correct) (South Dakota CDL Handbook 2025).
With safety as the paramount purpose of the endorsement process, South Dakota’s hazardous materials requiring the Hazmat endorsement include chemicals used in the oil and gas industry, explosives (due to mining and drilling operations), radioactive materials (due to proximity to nuclear facilities), gasoline, propane, and hazardous waste from industrial activities. Notable organizations requiring this endorsement include HollyFrontier Refining (Albuquerque), ExxonMobil (Carlsbad), and Los Alamos National Laboratory (Los Alamos). This sounds pretty lucrative, right? Let’s look at how we’ve eased the process for you.
Our tests mimic what you will face on the official DMV test. They are strategically designed to avoid all the extra information you’ll find online and go straight to the relevant material. The first item on your to-do list is to apply for your fingerprinting and background check. This response can take weeks, so use that time to study with our South Dakota DMV Hazmat Endorsement practice test. Once you receive the results and feel confidently prepared, you’ll visit the DMV with the necessary documents, pay the fees, pass the test, and immediately open the doors to this new world of opportunity.
