Louisiana Tanker Vehicles Test
You're hauling liquid loads through the chemical corridor between Baton Rouge and New Orleans — this test covers what happens when that load starts sloshing.
Select Test Mode
20 questions, 80% to pass. This test covers surge control, braking, and hauling liquids on Louisiana's bayou roads and interstates.
Key Topics

About the Louisiana Tanker Vehicles Test
Topics Covered
- ✓Surge and liquid movement — why it matters on I-10's curves near the Bonnet Carré Spillway, where a sudden stop can shove your tanker into the next lane
- ✓Braking with a partially filled tank — Louisiana's frequent rain and flooding mean you need to know how stopping distance changes when your load sloshes forward
- ✓Tank construction and types — different tanks for different liquids, like the chemical tankers you'll see on LA 1 through Port Allen

📘 Study Tips & State Info
Louisiana OMV examiners tend to focus on surge and braking questions. They know the roads here are flat but wet, and they want to make sure you understand how a liquid load behaves when you hit the brakes on I-12 heading into a thunderstorm. Study the difference between surge in a baffled tank vs. an unbaffled tank — that's a common question.
Another thing they emphasize: loading and unloading at chemical plants. You don't need to memorize every plant's rules, but you do need to know grounding procedures, how to check for leaks, and why you never fill a tank completely. The Louisiana CDL manual has a section on this — read it twice.
Finally, practice the braking distance questions. The manual gives you numbers for dry and wet pavement. Louisiana's average annual rainfall is 60 inches, so wet pavement applies here more than most states. If you can calculate the added stopping distance with a full tank, you'll ace the math questions.
Louisiana's Office of Motor Vehicles (OMV) handles all CDL testing. You can take the Tanker Vehicles test at any OMV location that offers CDL written exams. Major testing sites include Baton Rouge (Airline Highway), New Orleans (Veterans Memorial), Lafayette (Verot School Road), and Shreveport (North Market). Appointments are strongly recommended — walk-ins wait hours, especially after 10 AM.
Fees: The Tanker endorsement costs $20 on top of your CDL application fee. You'll pay when you apply for the endorsement at the OMV counter. Bring your Medical Examiner's Certificate (DOT physical) and proof of Louisiana residency. If you're renewing or adding an endorsement, bring your current CDL.
One Louisiana-specific wrinkle: the OMV uses a computer system that sometimes freezes during the test. If that happens, don't panic — tell the examiner and they'll reset it. Your answers are saved locally, so you won't lose progress. Also, Louisiana requires a vision screening before any CDL written test, so have your glasses or contacts ready.
About the Louisiana Tanker Vehicles Test
The Louisiana Tanker Vehicles endorsement is required for any Class A or B CDL holder who transports liquids in bulk — fuel, chemicals, milk, water, you name it. If the tank's permanently mounted on the truck or trailer, you need this test. Louisiana's chemical industry is the second largest in the country, so tanker work is everywhere along the Mississippi River from Baton Rouge down to New Orleans.
The test covers federal standards, but Louisiana examiners know the local realities. They'll ask about surge control on I-10's tight curves near the Bonnet Carré Spillway. They'll want to know you understand braking distances on wet roads — and it rains a lot here. You're not just memorizing a book; you're learning how to keep 8,000 gallons of liquid from pushing your truck through a guardrail on the Atchafalaya Basin bridge.
You'll take this test at any Louisiana OMV office that handles CDLs. It's a computer-based exam, 20 multiple-choice questions. You need 16 correct to pass. The test is part of your written knowledge exam and can be taken the same day as General Knowledge, as long as you've studied for both.
Don't underestimate the tanker test because it's short. Louisiana's roads — from the I-10 highrise in Lake Charles to the two-lane highways through sugarcane fields — demand you know how liquid load behaves. Surge, off-tracking, and braking are the big three. Get them right and you're ready for the skills test.
