Free Mississippi CDL HazMat Endorsement 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 DMV 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).
