Most drivers choose Class A CDL. It's required for any combination vehicle over 26,001 lbs — tractor-trailers, semis, and 18-wheelers. If you're not sure, this is the safest pick.
Class A CDL
Combination vehicles over 26,001 lbs GVWR. Required for tractor-trailers, tanker trucks, flatbeds, and most long-haul jobs.
Class B CDL
Single vehicles over 26,001 lbs GVWR. Common for straight trucks, large buses, dump trucks, and box trucks.
Endorsements
HazMat, Tanker, Doubles & Triples, and Passenger are add-ons for specific job requirements. If you're unsure, you don't need them — they can be added later.

Your Path to a Commercial Driver's License
To get a CDL, you must first study for and pass the permit exam at the DMV. After you receive your permit, you can take commercial vehicle driving classes and complete the required training. The final step is passing the official driving exam to earn your CDL. Our practice tests help you prepare for the DMV permit exam with real-style questions, and we also provide extra study materials and helpful resources to guide you through the process.
Official Mississippi CDL Handbook
The official Mississippi Commercial Driver License Manual covers every topic tested on the state's CDL knowledge exam — but it reads like a dense reference manual, not a structured study guide. A more effective way to prepare is with our General Knowledge practice tests. Our free Mississippi CDL permit practice test mirrors the format and content of the official exam and is fully up to date as of February 2026. Each practice test features 20 questions covering essential topics such as vehicle inspection, safe driving techniques, air brakes, cargo securement, driving emergencies, hazardous conditions, and Mississippi-specific commercial driving regulations. Unlike the official test, every practice question comes with a helpful hint and a detailed explanation of the correct answer — so you actually learn from every question you answer.
- Complete CDL regulations and Mississippi-specific requirements
- Safe driving techniques, vehicle inspection, and cargo handling
- All endorsement categories and testing requirements
Non-Domiciled CDL Information
Important information about non-domiciled commercial driver's licenses in Mississippi.
Federal regulations on non-domiciled CDLs are changing rapidly. The information below reflects the latest known state actions.
Mississippi does not issue non-domiciled CDLs. Individuals who are not domiciled in Mississippi cannot obtain a CDL from Mississippi — they must apply in their actual state of domicile or in a state that does issue non-domiciled CDLs. Since Mississippi does not participate in non-domiciled CDL issuance, the FMCSA Interim Final Rule of September 2025 and the subsequent court stay do not change Mississippi's position. Under the FMCSA final rule published on February 13, 2026, eligibility for non-domiciled CLPs and CDLs nationally is now limited to H-2A, H-2B, and E-2 visa holders. Drivers seeking a non-domiciled CDL must apply in a participating state.[FMCSA Final Rule]
English Language Proficiency (ELP)
Federal ELP enforcement applies to all CDL holders nationwide.
Federal ELP enforcement applies to all CDL holders nationwide. Here is how it is enforced in Mississippi.
Mississippi does not currently administer a separate state-level English Language Proficiency (ELP) test for CDL applicants. However, all Mississippi CDL holders are subject to federal ELP enforcement, which took effect on June 25, 2025. Under this enforcement, roadside inspectors conduct a two-step assessment: first, a conversational interview in English — no interpreters or translation tools are permitted — to evaluate whether the driver can communicate sufficiently in English; second, the driver must demonstrate the ability to read and interpret standard U.S. traffic signs. Drivers who fail either step of the assessment are placed out of service under CVSA guidelines. Mississippi CDL applicants should be prepared to demonstrate English proficiency during any roadside inspection or compliance review.
