Massachusetts General Laws Part I. Administration of the Government (Ch. 1-182) Ch. 85, § 11E

A police officer who observes a traffic law violation committed by a bicyclist may request the offender to state his true name and address.  Whoever, upon such request, refuses to state his name and address or whoever states a false name and address or a name and address which is not his name and address in ordinary use, shall be punished by a fine of not less than $20 nor more than $50.  An offender who refuses to state his true name and address may be arrested without a warrant for such refusal but no person shall be arrested without a warrant for any other traffic law violation committed while operating a bicycle.  A police officer shall use the ticketing procedure described in chapter 90C to cite a bicyclist for a traffic law violation but the violation shall not affect the status of the bicyclist's license to operate a motor vehicle nor shall it affect the bicyclist's status in the safe driver insurance plan.  When a citation is issued to a bicyclist, it shall be clearly indicated on the ticket that the violator is a bicyclist, and failure to do so shall be a defense to the violation.

The parent or guardian of a person under 18 years of age shall not authorize or knowingly permit that person to violate this section.  A violation of this section by a person under 18 years of age shall not affect any civil right or liability nor shall the violation be a criminal offense.  If the offender is under 16 years of age, the officer may give the notice to the parent or guardian of the offender.

All fines collected by a city or town pursuant to this section shall be used by the city or town for the development and implementation of bicycle safety programs.
