About the Vermont Tanker Vehicles Test
Topics Covered
- ✓Liquid surge and its effect on vehicle control — critical on Vermont's winding roads like Route 100 where sudden stops can shift thousands of gallons of milk.
- ✓Braking and stopping distance with a loaded tanker — ice and snow on I-91 mean you need double the space to stop a liquid load.
- ✓Loading and unloading procedures — especially important for fuel deliveries to farms and homes on steep, narrow driveways.

📘 Study Tips & State Info
Vermont DMV examiners focus on practical application. Don't just memorize definitions — think about how surge feels in a milk tanker going down a gravel road in Huntington. When you study load distribution, picture a heating oil truck making a delivery on a steep driveway in Stowe in January. That mental picture will help you answer the 'what would you do' questions.
The Vermont CDL manual has a section on tanker vehicles that covers the basics well. Pay extra attention to the diagrams showing baffled vs unbaffled tanks. Vermont has a lot of older unbaffled milk tankers still on the road, and examiners ask about that difference. Also, know the chain-up requirements for tankers — Vermont law requires chains on all commercial vehicles on posted routes during winter storms, and tankers are no exception. That's not on the written test directly, but understanding weight distribution with chains helps.
Practice the surge questions until they're automatic. The most common mistake Vermont drivers make is underestimating surge after a hard brake on a snowy road. The test will ask about that in a few different ways. If you practice with our simulator and set the time limit to 25 minutes, you'll be ready for the real thing.
The Vermont DMV administers CDL written tests at several locations. The primary offices for CDL testing are Berlin (Montpelier area), Rutland, Williston, and St. Albans. You need to schedule an appointment — walk-ins are not guaranteed, especially during peak seasons (spring and fall). To schedule, call the DMV at 802-828-2000 or use the online portal. The fee for the Tanker endorsement test is $10 per attempt, and you can pay with cash, check, or card.
Vermont does not require a separate tanker skills test if you already have a CDL and are adding the endorsement — you only need the written knowledge test. However, if you're getting your initial CDL with the tanker endorsement, you'll take the tanker skills test during your road exam. The skills test includes a pre-trip inspection focusing on the tanker's valves, hoses, and emergency shut-offs, plus a drive test with a loaded or simulated load.
One Vermont-specific quirk: some DMV offices use the older computer terminals that freeze up occasionally. If your test crashes, don't panic — the examiner will reset it and you won't lose your answers. Also, Vermont does not offer the CDL test in all languages, but English is the standard. If you need an interpreter, you must arrange that ahead of time with the DMV.
About the Vermont Tanker Vehicles Test
The Vermont Tanker Vehicles endorsement is required if you plan to haul liquids in bulk — think milk tankers from farms on Route 7, fuel trucks delivering heating oil on icy mountain roads, or water trucks on construction sites. This test covers surge, braking, and loading procedures specific to liquid cargo. Vermont's hilly terrain and long winters make tanker handling different than in flat states.
The test follows federal CDL standards but the Vermont DMV emphasizes practical knowledge for local conditions. You need to know how a partially filled tank sloshes on a downhill curve on I-89, and how to adjust your speed on a snow-covered road with a full load of diesel. Vermont examiners expect you to understand load shift, center of gravity, and the special risks of high-center liquid tanks.
You'll take this test at any DMV location that offers CDL written exams. The major offices include Berlin (Montpelier), Rutland, Williston, and St. Albans. Bring your CLP, proof of identity, and medical certificate. The test is computer-based and you'll get your results immediately. If you fail, you can retake it the next business day, but you'll pay the $10 fee again.
Vermont also has seasonal road restrictions that affect tanker weight limits. You don't need to memorize those for this test, but knowing they exist helps you understand why the manual talks about load distribution and tire pressure. Study the Vermont CDL manual's tanker section closely — it's shorter than you think, but every line matters.
