Nearly 300 vehicles have been towed for violations since the city’s winter parking ban took effect 3 a.m. Saturday, according to the Chicago Department of Streets and Sanitation.

The ban is enforced regardless of snow on 107 miles of main streets across the city between 3 a.m. and 7 a.m. until April 1.

Flyers were posted on vehicles parked on routes affected by the ban over the weekend in an effort to remind motorists to move their cars, the department said.

“Snow can accumulate quickly during winter storms, and crews need immediate access to the city’s most vital roads to ensure that they are safe for motorists,” Acting Commissioner John Tully said last year in a press release.

To check which streets are affected, residents may consult posted signs in their area or view a map of the roads included in the ban.

Violators for the 264 vehicles that have been towed so far could face a $150 fee, a $60 ticket and a storage fee of $20 per day, the department said. Vehicles are towed to two locations: 701 N. Sacramento and 10301 S. Doty Ave.

Last year, the department towed a total of 9,833 vehicles for violating the ban, according to the department.

The overnight parking ban is separate from another snow-related ban that affects another 500 miles of roads when there are at least 2 inches of snow fall, the department said.
