Six US cities tamper with traffic cameras for profit





Six U.S. cities have been found guilty of shortening the amber cycles below what is allowed by law on intersections equipped with cameras meant to catch red-light runners. The local governments in question have ignored the safety benefit of increasing the yellow light time and decided to install red-light cameras, shorten the yellow light duration, and collect the profits instead.
