A city proposal to allow all-purpose vehicles on Unalaska’s streets failed to move forward Tuesday. The Unalaska City Council voted against allowing the ordinance to proceed to its next meeting. Unalaska currently prohibits the use of all-purpose vehicles — like four-wheelers and all-terrain vehicles — on city streets. But a state law that went into effect this year opens the door to allow these modes of transport on public roads in places not prohibited by local law or ordinance.
