- ✓Proper venting and loading procedures for volatile cargo — ND's oil fields require you to know vapor recovery and static electricity prevention

📘 Study Tips & State Info
North Dakota examiners don't mess around with tanker questions. They want you to know the difference between a baffled and unbaffled tank, and why it matters when you're hauling water versus crude. Expect at least two questions on liquid surge — they love asking about the 'free surface effect' and how it changes on a turn. Study that section in the ND CDL manual until you can explain it to a rookie.
Another thing: ND adds state-specific questions about winter operation. You'll see stuff like 'What should you do if your tanker's vent freezes?' or 'How does cold weather affect your cargo's viscosity?' The manual covers this, but most drivers skip it. Don't. Know the cold-weather pre-trip steps and the proper way to warm up a frozen valve.
Finally, practice the test with a timer. The real deal feels cramped — 25 minutes for 20 questions sounds easy until you're second-guessing yourself. Our practice tests give you that same pressure. Use them to build confidence, and you'll walk out of the DMV with your endorsement.
North Dakota DMV handles all CDL testing at eight regional offices: Bismarck, Fargo, Grand Forks, Minot, Williston, Dickinson, Jamestown, and Devils Lake. You need an appointment — walk-ins aren't guaranteed. Call or book online at least a week ahead, especially in oil season when Williston and Dickinson fill up fast.
The written test costs $15. You'll also need a valid Medical Examiner's Certificate (DOT physical) before testing. If you're applying for a CDL for the first time, you'll take the General Knowledge test first, then the Tanker endorsement test. You must pass both to add the tanker endorsement to your license.
North Dakota follows federal standards, but the state adds one unique rule: if you're hauling crude oil or propane on certain state highways (like ND-22 or US-85), you're required to carry a copy of the ND Hazmat Transport Guidelines. Examiners may ask about that on the written test. Bring your manual, study that section, and you're set.
About the North Dakota Tanker Vehicles Test
North Dakota's tanker traffic isn't just delivering milk. You're hauling crude oil out of the Bakken, anhydrous ammonia for the fields, or gasoline to small-town stations. The Tanker Vehicles endorsement proves you understand how liquid cargo behaves — especially when you're fighting crosswinds on I-94 or hitting black ice on US-2 in January.
The test follows FMCSA standards, but ND examiners add their own flavor. They'll ask about surge control on gravel roads, proper venting for volatile loads, and what to do when your load shifts on a curve near Williston. You need to know the book, but you also need to think about real North Dakota conditions.
This is a 20-question multiple-choice test. You need 16 correct to pass — that's 80%. The DMV gives you 25 minutes. Our practice test mirrors that timing so you're ready when you sit down in Bismarck or Fargo.
We've built this specifically for North Dakota drivers. Every question ties back to something you'll actually face: hauling through a blizzard, parking on a frozen lot, or navigating the weigh stations on I-94. Study this, and you won't get thrown by the state-specific twists.
