The City Council today unanimously proposed an ordinance that lets police fine any scooter or ATV riders they see riding on one wheel, standing on the seats or doing other stunts on city streets.

The measure, which also bans riding the vehicles altogether on private land without owner permission, would let police confiscate multiple scooters and ATVs stored on private property that is not part of a licensed garage - or vehicles from riders who cannot prove they've registered them with the state.

City Councilor Josh Zakim (Beacon Hill, Back Bay, Fenway, Mission Hill) praised Mayor Walsh for proposing the ordinance. He said just last night, he was at a neighborhood meeting in the Back Bay when he looked out to see "three young men doing stunts down Newbury Street, harassing other drivers."

At-large councilor Michael Flaherty said that in addition to being a danger to pedestrians and other motorists, the vehicles are proving increasingly popular for criminals who use them to flee a scene.
