Quinn signs Chicago speed camera bill

Chicago Mayor Rahm Emanuel says a law just signed by Gov. Pat Quinn will improve safety for the city's students.

The legislation allows Chicago to use automatic speed enforcement cameras to monitor drivers around the city's schools and parks. The cameras will send $100 tickets if drivers go more than 5 mph over the limit.

Emanuel pushed for the legislation Quinn signed Monday. He says it just requires that drivers obey the law. Critics, however, argue such cameras don't improve safety but do generate revenue for local governments.

Starting in July, cameras may operate on school days from 6 a.m. to 8:30 p.m. Monday through Thursday and 6 a.m. to 9 p.m. on Friday. They also can operate near parks from an hour before opening to an hour after closing.
