About the Vermont Doubles and Triples Test
Topics Covered
- ✓Coupling and uncoupling procedures — Vermont examiners want the full sequence, especially when you're parked on an icy lot.
- ✓Trailer stability and rollover prevention — on Vermont's winding two-lane roads, a loaded double can tip if you don't slow down for curves.
- ✓Off-tracking and turning radius — longer trailers cut corners wide; on narrow Route 100, that's how you end up in a ditch.

📘 Study Tips & State Info
Vermont DMV examiners don't mess around with the Doubles and Triples test. They expect you to know the coupling procedure in order — every step. Don't skip the part about checking the air lines for frost or ice. That's a Vermont-specific detail they'll ask about.
Focus on how trailer length affects your turning radius. In Vermont, you'll be on roads like Route 2 through the Northeast Kingdom where a tight right turn means your rear trailer tracks way inside. The manual shows diagrams — study those. Also, practice the braking questions. They love asking about how to avoid trailer jackknife on a slippery downgrade. The answer is always about using your brakes properly, not over-braking the tractor.
One more thing: the Vermont CDL manual includes a section on winter operation for combination vehicles. Read it. They pull questions directly from that chapter. If you can explain why you need more following distance in snow with two trailers, you'll pass.
Vermont DMV administers the Doubles and Triples test at all CDL testing locations. You'll find them in Montpelier, Burlington, Rutland, St. Johnsbury, and Bennington. You must make an appointment — walk-ins aren't accepted for CDL tests. Call ahead or use the online scheduler on the Vermont DMV website.
You need to pass the General Knowledge test and the Combination Vehicles test before you can take the Doubles and Triples endorsement test. Bring your Medical Examiner's Certificate and your CLP. The fee for the endorsement is $10, added to your CDL license fee. Vermont does not offer the test online — you take it on a computer at the DMV office.
If you fail, you can retake it the same day if time allows, or come back another day. There's a $10 retest fee. Most people pass on the first try if they study the manual and use a practice test like ours.
About the Vermont Doubles and Triples Test
Vermont's not flat. If you're pulling doubles or triples on I-89 between Burlington and Montpelier, you're climbing grades, hitting tight curves, and dealing with black ice from November through April. The Vermont Doubles and Triples test makes sure you know how to handle that — not just the federal basics.
You need this endorsement if your Class A CDL will pull more than one trailer. That's common in Vermont's logging industry, fuel delivery, and some agricultural hauling. The test is 20 questions, 80% to pass, and it's added to your General Knowledge and Combination Vehicles tests.
Vermont DMV examiners expect you to know the step-by-step coupling sequence cold. They'll also ask about winter-specific adjustments — like how much extra following distance you need on a snowpacked Route 7. Don't expect generic questions. These are written for the roads you'll actually drive.
Our practice test uses real Vermont scenarios. You'll get questions about off-tracking on the tight turns of Route 100, trailer sway in crosswinds across the Champlain Valley, and braking techniques on the long downgrades of I-91. Pass this, and you're ready for the DMV.
