But, as police, court administrators, and Registry officials became aware this spring, the law also inadvertently did away with punishments for bicyclists who fail to pay tickets.

Without any clear way to collect fines or punish those who ignore tickets, authorities have been left with a procedure reliant on the honor system. As a result, it appears that a number of police departments are choosing not to ticket bicyclists. Boston police, as of last week, had issued 60 warnings - but zero tickets - to bikers since the Hubway added 600 bikes to city streets.
