The two winter rules drivers confuse
Chicago has a posted overnight winter parking ban on 107 miles of vital arterial streets, and the City also identifies a separate network of snow routes where parking can be restricted when there is enough snow on the ground. The signs are different, and drivers should read the exact sign before leaving a vehicle.
Overnight winter ban
Applies daily from 3:00 a.m. to 7:00 a.m. between December 1 and April 1 on posted routes, regardless of whether snow is falling.
2-inch snow routes
Separate posted snow routes can restrict parking when snow reaches at least two inches on the ground, regardless of date or time.
Normal signs still apply
Meters, residential zones, street cleaning notices, tow zones, and No Parking signs can still layer on top of winter rules.
How to read winter parking signs
Before parking overnight in winter, scan the block for permanent seasonal signs. If a route is part of the overnight ban, the restriction is not optional and does not depend on weather.
Check both sides of the street
The rule can be posted on one side or on a corridor with signs you may not notice from the driver seat.
Look beyond the space
Walk to the nearest pole in both directions if you are parking near an arterial street or busier corridor.
Use extra caution near main roads
The winter ban is designed around keeping major streets open for emergency access, transit, salting, and plowing.
aSpot winter workflow
Use aSpot to save your car location and build a winter parking habit: check the sign, save the spot, and avoid leaving the car overnight on any block with unclear seasonal restrictions.
Before overnight parking
Confirm there is no winter ban sign, no snow-route sign, no meter limitation, and no residential-permit conflict.
During storms
Avoid main-street curb spaces if you do not fully understand the posted snow restriction.
After parking
Save the vehicle location so you can find it fast if snow changes your plan.
