View All PlansThe Green Mountain State’s major industries, including dairy, forestry, renewable energy, and regional logistics, all rely on drivers with a Class A Commercial Driver’s License (CDL). Because of this strong demand, you are making a wise career decision in pursuing licensure. To legally operate a combination vehicle (any rig where the towed unit exceeds 10,000 pounds GVWR) in Vermont, you must earn a Class A CDL. One of the requirements for earning this license is passing the CDL Combination Vehicles Knowledge Test, which consists of 20 multiple-choice questions. You must answer at least 16 correctly (80%) to pass. If you don’t pass, you must wait a minimum of one business day and may have to pay a retest fee.
You’ll need to understand coupling and uncoupling procedures, air-brake systems, trailer inspection, and how to prevent skids, rollovers, and jackknifing on Vermont’s winding roads. The test is administered by the Vermont DMV, and your results will stay valid for 180 days so you can complete the rest of the CDL process.

In addition to passing this test, you’ll need to complete Entry-Level Driver Training (ELDT) through an FMCSA-approved provider, pass the CDL General Knowledge Test, and obtain and hold your Commercial Learner’s Permit (CLP) for at least 14 days. After this holding period, you must pass the behind-the-wheel Skills Test in a combination vehicle. That sounds like a lot of work, but trust us. Our experts have removed unnecessary fluff and designed practice tests and guides to speed learning and boost retention!
Our Free Vermont CDL Combination Practice Tests mirror the official DMV exam. Each response you provide is met with instant feedback and hints as needed, a method proven far more effective than end-of-assessment comments. The practice tests help you uncover common testing traps, distractors, tricky wording, and double negatives that are sometimes used in test questions. Once you’ve aced this one, check out another here: https://driving-tests.org/vermont/vt-cdl-combination-test/.
Haul agricultural goods from Addison County, timber from the Northeast Kingdom, or freight along I-89 and I-91 with job security since Vermont’s economy depends on Class A licensed CDL drivers. Additionally, you’ll want to pass the Air Brakes Knowledge Test and a skills test in an air brake-equipped vehicle. This removes the “L” restriction from your CDL. Most combination vehicles are equipped with air brakes, so don’t skip this! Prepare using our Vermont Air Brakes Practice Tests. Also, check out our Vermont endorsement practice tests designed to help you pass the official exam on your first attempt, adding more marketability to your CDL: https://driving-tests.org/vermont/vt-cdl-hazmat-practice-test/.
