Chicago's Winter Overnight Parking Ban Explained
Every winter, Chicago activates an overnight parking ban on designated snow routes from December 1 through April 1. If your street is a snow route and you leave your car parked overnight, you risk a fine and towing — even if it hasn't snowed recently. Here's how the Chicago overnight parking ban works.
What is the overnight parking ban?
Chicago's overnight parking ban prohibits parking on designated snow routes between 3am and 7am from December 1 through the last day of March. The ban applies every night during this period regardless of weather conditions — you don't need active snowfall for enforcement to occur.
The city designates 107 miles of arterial streets as snow routes. These are the major roads the city prioritizes for plowing and salt treatment after a storm.
How to know if your street is a snow route
Snow route streets are marked with distinctive yellow and black signs that say "Snow Route — No Parking 3am to 7am Dec 1 thru Last Day of March." If you see this sign on your block, the ban applies to you every night from December through March.
The City of Chicago also maintains a map of all designated snow routes on its website, searchable by address.
Penalties for violations
- Parking ticket: $60 for parking on a snow route during restricted hours
- Towing: Vehicles are frequently towed (not just ticketed) on snow routes — especially after a snowfall when plows need the full lane width
- Towing fee: $150+ plus daily storage
Towing is more likely after an actual snowstorm, when the city deploys crews specifically to clear snow routes of parked vehicles.
The ban vs. street sweeping
The overnight parking ban and street sweeping are separate programs with overlapping seasons. From April 1 onward, the overnight ban ends — but street sweeping begins. The transition period (late March into early April) can be confusing: sweeping starts April 1 on most schedules, while the overnight ban ends on the last day of March.
Best practices for winter parking in Chicago
- Check your block for snow route signs before winter begins
- If your block is a snow route, plan to move your car before 3am or after 7am
- After a major snowstorm, assume your car will be towed if it's on a snow route — even during daytime hours when emergency bans are sometimes declared
- Sign up for city emergency alerts at notifychicago.org to get real-time updates when parking bans are declared
