Authorites Manipulating Traffic Lights For More Challans

Authorities in six US cities were found guilty of shortening the yellow light duration at traffic signals. Short yellow light times at intersections lead to more traffic violations, and thus more challans and more money. Local governments in Chattanooga, Tennessee; Dallas, Texas; Springfield, Missouri; Lubbock, Texas; Nashville, Tennessee; and Union City, California had intentionally cut down the amber signal duration to make more profits. Its wake up time guys.

Next time you hit the road, then don't forget to the time the amber light. It should stay lit for atleast 3.9 seconds. It quite likely that many more cities are following the policy of more challans more money. Raise your voice if you find that you are being fooled into paying for illegal challans.
Update:- The city of Chattanooga was forced refund $8800 in red light cameras tickets issued to motorists trapped by an illegally short yellow time.
