Attached is a link of a law floating around MA. The basics are this, No riding under 14 years old. 16-18 nothing over 90cc. All offences will be CRIMINAL not civil, fines and possible jail time. If someone calls the police on you a department of social services case is opened to determine if you are a fit parent. All of the DCR, Rangers, etc will have full police power. It didn't pass in July and is on hold till the fall session for now. This bill did pass the house of representatives earlier this year but not the senate.
