Mississippi Class B to Class A Upgrade Program

Class B to Class A Upgrade Program for Mississippi CDL Applicants

Mississippi supports growing automotive and food processing freight along key Southeast freight corridors. With automotive manufacturing, poultry and food processing, shipbuilding logistics driving much of the freight in Mississippi, the Class B to Class A Upgrade Program material below is the part of the Mississippi CDL that those employers screen for first.

The Mississippi Class B to A upgrade: Combination Vehicles and Air Brakes knowledge tests at Mississippi Department of Public Safety, then a Class A skills test. Since February 2022, ELDT theory and behind-the-wheel training must also be logged with an FMCSA-registered provider before Mississippi Department of Public Safety will schedule the test.

Where Mississippi drivers use this

• Almost every Class A and Class B vehicle in Mississippi; skip this test and your CDL carries an L restriction
• Automotive manufacturing: just-in-time parts hauling between assembly plants and suppliers
• Poultry and food processing: refrigerated (reefer) loads of produce and food moving to distribution centers and out of state
• Shipbuilding logistics: regional and over-the-road distribution runs for grocery, retail, and e-commerce freight
• Timber and paper: flatbed and step-deck loads of steel, lumber, and building materials

Most Mississippi CDL work runs the I-20, I-55, I-59 corridors and the Jackson area, so the examples in the practice questions lean on the vehicles and loads you will see there.

Testing, appointments, and fees are handled by Mississippi Department of Public Safety. See the Mississippi CDL classes and Mississippi endorsements pages for the full licensing picture.
