The law, signed last week, requires state agencies to come up with a plan to increase the number of cameras along expressways in Cook County. 

The new law is named for postal worker Tamara Clayton who was fatally shot in her car earlier this year while traveling on Interstate 57 near Oak Forest.

After a significant upswing in gunfire reported along Chicago's expressways, lawmakers in Springfield decided to act. One of the bill's co-sponsors, State Senator Jacqueline Collins, says Illinois' roadways need to be made more secure.

For those worried that the cameras will be used to catch drivers doing all sorts of different things rather than just keeping tabs on those who brandish weapons, The law, signed last week:

"...requires state agencies including Illinois State Police and the Department of Transportation to come up with a plan to increase the number of cameras along expressways in Cook County. The cameras can be used only for firearm-related offenses or to detect roadway hazards."

The law takes effect in 2020.
