The red light camera controversy is expanding and now yellow lights are being scrutinized.
On Tuesday, a judge looked at five separate speeding tickets, and threw two out after ruling the yellow light times lasted only 2.9 seconds.
The judge told the Chicago Tribune that he throws out up to 70% of the red light traffic violations that he sees, because in his opinion the yellow light is too short.
By law, the yellow light must last at least three seconds.
The website, http://www.redlightdoctor.com measured many intersections across the city and claims a number have yellow lights that are too quick.
The city is under fire for a spike in red-light camera tickets.
The Chicago Tribune reports thousands of drivers received tickets they didn't deserve over the past seven years.
City Hall officials claim the amber lights meet traffic standards and make intersections safer.
