From the VT site:
"Quarantine means staying at a home or dwelling before doing any activities outside of the home, like grocery shopping or getting together with friends or family. People in quarantine should separate themselves from others and check themselves for symptoms."
there is this:
"
Quarantining Before Coming IS an Option
If you plan to travel to Vermont in a personal vehicle (including a rental vehicle or private plane), you may complete either a 14-day quarantine or a 7-day quarantine followed by a negative PCR test in your home state and enter Vermont without further quarantine restrictions. Continue to quarantine until you travel to Vermont."

It is basically unenforceable, but if you try and actually follow VT's rules, you cannot have a child going to school, a job outside the house, and/or a spouse/partner/roommate who works outside of the house. You cannot shop for food or come in contact with the person in your house who does shop for food during the Quarantine period (or you must have food delivery). If you try and quarantine in your house, you better have a large house or a small family.
But, as I said, it is unenforceable.
