Most of my commute is in MA. I live two miles from the CT border, pass through CT for ~10 miles, then the remaining ~26 miles are in MA.
Anyway, I've never heard of anyone anywhere ever having any legal trouble with coasting, but it's good to know and obey the laws either way.
RI can be real weird about laws. The populace is strongly left-aligned, and our presidential voting history is almost entirely on that side. OTOH, we elect lots of republican governors. Our laws have the same split; lots of heavy liberal stuff, sprinkled with a few strong conservative or libertarian laws. We've got a strong
castle doctrine, for example, though not the wide-open gun rights that you have in VT.
