As a tanker truck driver in Mississippi, you may transport fuel, chemicals, or agricultural liquids like fertilizers and pesticides. These materials are toxic to humans and the environment, requiring commercial drivers to hold both a Tank Vehicles (N) and a HazMat (H) endorsement on their Commercial Driver’s License (CDL).
As you drive down Interstate 55 from Memphis to Jackson, you’ll notice how even a slight shift in the liquid cargo affects the truck’s stability. That’s why tanker trucks must keep a long distance from other vehicles. Stopping a fully loaded tanker takes time, and liquid surge can make it more challenging during winter months when ice is common in the Magnolia State. Here, the Department of Public Safety (DPS) ensures that all licensed tanker truck drivers are fit for this job.
Applicants must pass a written knowledge test on various aspects of driving a tanker, including safety protocols, loading and unloading procedures, transporting liquids and handling emergency situations. If you haven’t yet done so for your CDL, you must also pass a skills test in a vehicle of the license class you are applying for. An essential resource is the official 2026 CDL manual (Mississippi CDL Handbook 2026), but some students find the material too difficult to study. Learning shouldn’t feel like a challenge, especially when there are many ways to make it a rewarding experience.
