The grace period for speeders is over: The camera at 3137 W. Peterson Ave. will begin issuing tickets on Sunday, according to the Chicago Department of Transportation. The cameras at 4433 N. Western Ave., 4436 N. Western Ave. and 4432 N. Lincoln Ave. will follow suit on Monday.
Initially, motorists will only be ticketed for speeds 10 miles per hour or more above the posted limit. That threshold will gradually be lowered, CDOT said.
Fines are $35 for vehicles caught traveling six to 10 miles per hour over the posted speed limit and $100 for vehicles traveling 11 or more miles over the posted speed limit.
The hours of enforcement coincide with the parks' hours of operation, typically 6 a.m. to 11 p.m., seven days a week, with a 30 miles-per-hour limit.
The speed cameras are intended to create "safety zones" of one-eighth mile around Chicago's schools and parks.
