📘 Study Tips & State Info
Mississippi examiners focus on the practical application of surge theory. They want you to understand why a tanker sways when you brake hard. Focus on the physics, not just memorizing steps. Expect questions about driving in rain — Mississippi sees over 50 inches of rain annually. Know how hydroplaning affects a partially loaded tanker.
The Mississippi CDL manual has a section on tanker inspections. Study it thoroughly. Examiners often ask about the order of checking compartments and why you must check for leaks after filling. Also, practice identifying low bridges and narrow roads — Mississippi has plenty of both. If you can't explain why you'd take a curve slower in a tanker than a dry van, you won't pass.
Use the practice test on cdlstudybuddy.com to get a feel for the question style. But don't just memorize answers — understand each concept. Mississippi examiners can rephrase questions, and if you don't know the principle, you'll get stuck.
Mississippi CDL testing is handled by the Mississippi Department of Public Safety (DPS) Driver Services. You can take the Tanker Vehicles test at any DPS exam station that offers CDL written tests. Popular locations include Jackson (4720 I-55 North), Gulfport (13000 Dedeaux Road), and Tupelo (2585 South Eason Blvd). Appointments are required — walk-ins may not be accepted. The fee for the tanker endorsement written test is $7 (as of 2025). You must already hold a valid CDL or CLP with the appropriate class. You'll also need to pass a vision test and provide your Medical Examiner's Certificate.
If you plan to haul hazardous materials in a tanker, you'll need both the Tanker and Hazmat endorsements. The Hazmat test is separate and requires a TSA background check. Mississippi DPS does not offer online testing — everything is in person. Make sure you bring proper ID, proof of residency, and your Social Security card.
Mississippi has a lot of rural testing sites with limited hours. Check the DPS website for your local station's schedule. Some smaller offices only offer CDL testing one day a week. Plan ahead.
About the Mississippi Tanker Vehicles Test
The Mississippi Tanker Vehicles endorsement is for anyone who hauls liquids in bulk — fuel, milk, chemicals, water. If the load sloshes around, you need this test. Mississippi has its own set of challenges: tight curves on Highway 49, long grades on I-55 near the Louisiana line, and sudden thunderstorms that turn pavement into a slick mess.
The test follows federal standards, but Mississippi examiners add local flavor. They'll ask about driving during our heavy rain season and how surge affects handling on two-lane roads. You need 20 questions answered, 16 right to pass. That's 80%.
You'll take this at any Mississippi DPS exam station. Appointments are mandatory. Bring your CLP, medical card, and $7 fee. The test covers surge, braking, rollover risks, and inspection. Don't blow it off — tanker rollovers are the leading cause of single-vehicle truck accidents in the state.
Know the physics. Understand why a partially loaded tanker is more dangerous than a full one on a curve. Mississippi's heat can also cause vapor expansion in fuel tankers — that's a real question on the test. Study the Mississippi CDL manual, especially the tanker section.
