About the Vermont Combination Vehicles Test
Vermont's narrow, winding roads and long winters make combination vehicle driving a real challenge. You'll often share the road with logging trucks and milk tankers hauling raw milk from dairy farms. That's why our practice test focuses on real-world scenarios you'll actually face on routes like Route 7 or US 2.
We cover air brakes because you'll need them on mountain descents, especially when snow and ice hit. Coupling and uncoupling skills matter when you're picking up a loaded trailer at a farm in Addison County. Pre-trip inspections aren't optional here — cold weather means you check every air line and glad hand twice.
Our test uses the latest Vermont CDL manual. You get 20 questions, and you need 80% to pass. It's the same format as the real DMV written test. Miss a question? We show you the correct answer right away. Take it as many times as you need — it's free.

Study Tips
Use the Vermont CDL handbook – it's the only source the DMV tests from. Highlight the combination vehicle chapter twice. Focus on air brake diagrams and coupling procedures. You'll see those questions repeated on the exam.
Practice pre-trip inspection steps out loud. Vermont examiners want to hear you say each check. Don't just point – name the part and its condition. Bring your medical card and a valid driver's license to the test. Schedule your appointment online at least two weeks ahead; slots fill fast around harvest season.
Vermont Specific Information
Vermont DMV offers CDL knowledge tests at Montpelier, Rutland, and Williston offices. You must schedule an appointment online – no walk-ins allowed. The knowledge test costs $30. You can pay by credit or debit card. Bring your current driver's license, proof of residency, and your medical examiner's certificate.
For the skills test, you'll need a vehicle that matches your combination vehicle endorsement. The DMV doesn't provide trucks. If you fail the knowledge test, you must wait one business day before retaking it. Study our practice test first to save time and money.
