Updated for March 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.

Here's an inside look at how we maintain the highest quality in our practice tests.

Content Creation and Verification Process

Alignment with Official Manuals:
Every question we develop is based on the most recent version of each state's official driving manual. Our team regularly monitors each state DMV's website for the latest updates to ensure our practice tests are always aligned with the most current information.
Community Feedback Integration:
We leverage feedback from our vast community of users to understand which topics are most frequently tested. This helps us focus on the areas that are most relevant and beneficial for your preparation.
Expert Content Creation:
Our in-house editor, Steven, who has extensive experience in driver education, crafts each question with precision. He conducts a thorough review of each question against the official manuals to ensure accuracy.
Rigorous Review Process:
Once Steven has finalized a set of questions, our team conducts a joint review session. This second level of scrutiny involves content accuracy, proofreading, and fact-checking to eliminate any errors.
User Feedback Mechanism:
After a question goes live on our site, we keep the lines of communication open. Each question features a feedback button, inviting users to report any issues or errors. This continuous feedback loop allows us to address and rectify any concerns promptly.
Responsive Updates:
In line with our commitment to accuracy, we quickly update our practice questions to reflect any changes in the DMV manuals. Additionally, we update the free electronic copy of the state's driver's license manuals on our site, typically within a few days after the DMV publishes them.
