Pittsfield's wintertime overnight parking restrictions take effect on Saturday, Dec. 1, according to the police department.

Parking on city streets, sidewalks, or tree-line areas is prohibited between 11 p.m. and 7 a.m.

Fines are $25 and vehicles can be towed, at the owner's expense, if they're obstructing public safety operations.

In the event a snow emergency is declared, any vehicles obstructing snowplowing operations will be towed at the owners' expense.

During a snow emergency, vehicles may be parked in the three-hour public parking areas of the Summer Street and McKay Street parking garages between 11 p.m. and 7 a.m.

No vehicles are permitted to park in any open, municipal parking lot between the hours of 12 a.m. and 7 a.m., so the lots may be properly plowed and sanded.
