Carriers in Mississippi routinely prioritize HAZMAT-endorsed applicants and pay sign-on bonuses to get them.

You can finish the FMCSA theory portion before lunch — and keep your current schedule untouched.

The HAZMAT endorsement order in Mississippi

Every state runs the TSA background check and the hazmat knowledge test, but not in the same order. This is Mississippi's, from the DPS's own rules.

Hazmat TSA enrollment and fingerprinting through a TSA Universal Enrollment center (no longer done at DPS offices), then the hazmat knowledge test at a CDL station; DPS recommends enrolling before you test.

Who issues it

Mississippi Department of Public Safety, Driver Service Bureau.

Official DPS CDL page ›

Age and permit

Age: 18 for in-state driving; 21 to cross state lines, drive a school bus, or haul hazmat.

Permit hold: 14 days.

Will Mississippi accept online hazmat theory? Yes, by federal rule. Federal rule 49 CFR 380.703(i) says that state qualification requirements for theory instruction do not apply to providers offering that instruction only online. So your state accepts theory from any provider listed on the FMCSA Training Provider Registry, including ELDT365, and no state can require the online theory portion to come from a state-licensed school. States can add their own rules for the behind-the-wheel part, and several do; those are listed below. 49 CFR 380.703(i)

Mississippi HAZMAT Endorsement FAQ

Common questions from Mississippi CDL holders adding the H endorsement.

Is the ELDT365 HAZMAT course accepted in Mississippi?
Yes. ELDT365 is registered on the FMCSA Training Provider Registry (TPR). Every Mississippi DPS location accepts completion records submitted through the TPR, and we submit yours automatically the moment you finish.
Do I need a CDL before taking the HAZMAT course in Mississippi?
You don't need the CDL in hand to start the theory course, but you'll need a valid Mississippi CDL (Class A or Class B) before the DPS can add the H endorsement to your license. Most drivers take the HAZMAT theory training alongside or right after their CDL training.
How long does the Mississippi HAZMAT theory course take?
Most Mississippi drivers finish the HAZMAT theory in one sitting. The course is self-paced — pause and resume anytime on any device.
What happens after I finish the HAZMAT course?
Your completion is auto-uploaded to the FMCSA Training Provider Registry. From there you complete your TSA fingerprint/background check and pass the HAZMAT written test at your local Mississippi DPS office. You don't need to bring a paper certificate — the DPS pulls your training record from the federal registry.
How much does the Mississippi HAZMAT endorsement cost in total?
ELDT365 covers the FMCSA-required theory training for $20. You'll also pay a TSA background check fee (paid directly to TSA) and whatever Mississippi DPS charges for adding an endorsement to a CDL. Those two fees vary and go directly to the TSA and MS state — not to us.
Can I take the Mississippi HAZMAT course on my phone?
Yes. ELDT365 is fully mobile-friendly. Many Mississippi drivers complete the HAZMAT course on their phone during breaks, layovers, or at home.
How much more will I earn with a HAZMAT endorsement in Mississippi?
Most HAZMAT-endorsed drivers earn an extra $5,000–$15,000 per year compared to non-endorsed CDL drivers — with fuel, chemical, and industrial freight lanes running through Jackson, Gulfport, and Southaven being common HAZMAT routes in Mississippi. Actual earnings depend on the carrier, the freight, and your experience level.
