Chicago triples the 'grace period' for running red lights

Chicago motorists caught on camera blowing through red lights will have triple the "grace period" before being slapped with $100 tickets, under a change made Monday that could reduce the number of tickets issued by nearly a third.

Last year, the city issued 586,415 red-light tickets -- and about 29 percent of those went to motorists who entered the intersection between one-tenths and three-tenths of a second after the light had turned red.

By tripling the "grace period" to three-tenths of a second -- as suggested by the Northwestern University Traffic Center -- the city is likely to issue 29 percent fewer tickets, according to Transportation Commissioner Rebekah Scheinfeld.
