If you're riding your ATV without registering it with the State of Vermont, you're riding illegally. Make sure that your ATV is legal to ride in your state. The cost of a ticket is far greater than the minimal cost of registering your ATV.
In the State of Vermont, ATV registrations (limited use off-highway plates) are valid for a period of 2-years. If you are a resident of Vermont, you must bi-annually register ATV's owned or leased for a period of more than thirty days and operated by them, unless the ATV is currently registered in Vermont by another party. This regulation applies to any ATV that is operated or garaged.
The State of Vermont also requires that any ATV riders between the ages of 12-16 years of age do not ride unsupervised and any riders under the age of 18-years old must possess a safety certificate for riding ATVs.
When it is time to register your ATV, simply go to the Vermont DMV main office which is located in Montpelier. You will need to show a valid drivers license as well as a proof of ownership for your ATV. Certain satellite offices in Vermont are equipped to handle registration of your ATV, check with a DMV close to home before you make the trip to Montpelier.
When registering your ATV, you will need to attest that your ATV has working brakes, headlights, noise muffler (Vermont has specific decible limits by county) and a spark arrestor in place. After you register you ATV for the first time, registering your ATV after your 2-year time limit expires can be done via mail.
Vermont has a great riding experience awaiting you and your ATV, make sure and ride those trails safely and legally.
