Free Mississippi CDL HazMat Practice Test 2025
Transporting cargo through Mississippi, you’ll experience generally flat terrain but also a few hilly areas in the northern region and rolling hills in the east-central section. The Gulf Coast and the Mississippi River add a breathtaking element to the state, especially at sunrise and sunset. Adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL) is an amazing way to enjoy all of this while increasing your job opportunities and potentially your pay!
The Hazmat endorsement is your key to the opportunity to transport materials that the U.S. government has classified hazardous. In the Magnolia State, these materials include agricultural chemicals (fertilizers, pesticides), petroleum products, and various industrial chemicals. Some major organizations in Mississippi, such as Ergon Inc. in Jackson (petroleum refining and transportation), Chemours Company in DeLisle (chemical manufacturing), and Howard Industries in Laurel (industrial products), rely on drivers with this endorsement.
That’s a lot of opportunities – and these just scratch the surface. Let’s look at how you obtain this valuable endorsement. There are several steps to ensure that drivers are properly trained to handle these materials safely. First is the mandatory fingerprinting and background check conducted by the Transportation Security Administration (TSA). Results from TSA can take weeks, so you’ll want to study and practice in the meantime for the second step: the DPS knowledge test. This test covers federal regulations, substance handling, packaging, quantity limits, and transport configurations for hazardous materials. With a score of 80% on Mississippi’s 30-question knowledge test, drivers pass and unlock new opportunities (Mississippi CDL Handbook 2025).
Feeling slightly overwhelmed? We’ve got your back. Our Mississippi DPS Hazmat Endorsement practice tests are designed to avoid any unnecessary information and focus on what matters. We also provide immediate feedback on each response so you learn efficiently without waiting until the end for corrections. Studies have shown that this approach substantially increases the speed at which individuals learn and retain information. Lastly, we have streamlined the content of our practice tests to resemble what you will face on the official DPS test (https://m.driving-tests.org/mississippi/ms-cdl-hazmat-practice-test/). Once you receive your TSA results and feel prepared from all the practice, you’ll visit the DPS with the necessary documents, pay the fees, and pass the test with flying colors as beautiful as a Mississippi autumn!
