Minneapolis officials declared a snow emergency beginning Tuesday, according to a city news release.

In a snow emergency, parking restrictions go into effect so crews can more easily plow streets for emergency vehicles. Parked vehicles are required to move to avoid a tow and a ticket, according to the release.

Beginning at 9 p.m. Tuesday and ending 8 a.m. Wednesday, no parking is allowed on either side of a snow emergency route until the street is fully plowed.

Between 8 a.m. and 8 p.m. on Wednesday, drivers parking on a non-snow emergency route are allowed to park only on the odd side of the street until the even side is plowed. Also, parking isn’t allowed on either side of a parkway until the street is plowed.

On Thursday, from 8 a.m. to 8 p.m., drivers can’t park on the odd side of any non-snow emergency route until that side is plowed.

The release also encouraged homeowners and businesses to clear sidewalks. Minneapolis law requires property owners remove snow from sidewalks at homes and duplexes within 24 hours after snow falls.
