If you drive one of those cool new scooters, you won't be able to pull up on the sidewalk and park it as of July 31. You will have to register, and follow the rules of the road just like any other vehicle. A new law, chapter 523 of the acts of 2008 changes the rules in several ways. It creates a new category of limited use vehicles which can travel more than 30 mph but not exceed 40mph.
The Globe's article outlines may of the details, including ordinance variations in some cities. We have not found any related regulations from the Registry yet. The page they have on scooters and motorcycles is out of date. We'll update as regulations become available.
