Mississippi CDL practice tests

How CDLs work in Mississippi

In Mississippi, commercial driver licensing is administered by the Mississippi DPS. Like every U.S. jurisdiction, Mississippi follows the federal CDL standards published by the Federal Motor Carrier Safety Administration (FMCSA), which means the rules you study using LicenseReady apply directly to the test you’ll take. The handbook your DMV office issues is essentially the FMCSA CDL Manual with a state cover and a few jurisdiction-specific notes added at the front and back. For step-by-step eligibility, fees, and the application process, see the Mississippi CDL requirements page.

To earn a CDL in Mississippi, candidates begin with the General Knowledge exam, which every Class A, B, and C applicant must pass. From there, additional endorsement exams unlock specific privileges: Air Brakes for any vehicle with a compressed-air braking system, Combination Vehicles for Class A applicants pulling a trailer, Hazmat (H) for placarded loads, Tanker (N) for bulk liquids, Doubles/Triples (T) for multi-trailer combinations, Passenger (P) for vehicles built for 16+ riders, and School Bus (S) on top of P for student transport.

The exam in Mississippi

The General Knowledge exam in Mississippi is a multiple-choice test of roughly 50 questions; you must score at least 80% to pass. Endorsement exams range from 20 to 30 questions depending on the category, also at the 80% mark. Tests are typically administered on a touchscreen at a Mississippi DPS service center, though some locations still use paper forms. You may take the test as many times as needed to pass, although most DMVs charge a small re-test fee and require a 24-hour wait between attempts.

What to bring to the Mississippi CDL exam

Bring proof of identity, proof of Mississippi residency, your Social Security number, and your current driver’s license. Hazmat applicants additionally need to complete a TSA threat assessment and pay the federal background-check fee before the endorsement is added. Most candidates arrive with their CDL handbook tabbed to the air-brake and inspection sections so they have a quick reference on the way in. Allow at least two hours at the DMV office: most of that time is lines.

Practice tips for Mississippi drivers

The fastest path to a passing score is to drill the General Knowledge exam until you can finish a full set above 90% in under fifteen minutes. Once that’s solid, move on to Air Brakes and Combination Vehicles — the two endorsements nearly every Class A applicant in Mississippi ends up taking. Hazmat is the longest exam at 30 questions and the only one that requires a federal background check, so plan accordingly if your job requires it. Use the study guides for a quick refresher between practice runs.
