The Chicago Department of Transportation announced a new policy earlier this week that will increase the "grace period" -- the time between when a traffic light turns red to when a ticket is automatically issued. The decision has been made to increase the time from 0.1 seconds to 0.3 seconds, following recommendations part of a recent study of its red-light cameras. Ars Technica reports: This will bring the Windy City in line with other American metropolises, including New York City and Philadelphia. In a statement, the city agency said that this increase would "maintain the safety benefits of the program while ensuring the program's fairness." On Tuesday, the Chicago Tribune reported that the city would lose $17 million in revenue this year alone as a result of the expanded grace period. Michael Claffey, a CDOT spokesman, confirmed that figure to Ars. "We want to emphasize that extending this enforcement threshold is not an invitation to drivers to try to beat the red light," CDOT Commissioner Rebekah Scheinfeld also said in the statement. "By accepting the recommendation of the academic team, we are giving the benefit of the doubt to well-intentioned drivers while remaining focused on the most reckless behaviors."
