JEFFERSON CITY, Mo. (KMOX) -  You might notice yellow lights getting a bit longer at intersections in your neighborhood, and throughout Missouri.

Governor Jay Nixon has signed a law regulating the minimum length before yellow lights change over to red.

Sen. Jim Lembke sponsored the bill — he’s observed that many communities decide to shave some time off the yellow once they install red light cameras.

“The concern that we had where they’re using photo enforcement is that in some of the municipalities they might be shortening the times on the yellow lights in order to write more tickets,” Lembke told KMOX News.

He cites the case of Texas, where lengthening yellow light times by just one second cut the number of red light tickets issued in half.
