OK, let’s start with a memory:
Well, the meaning of a yellow light is changing, according to the National Journal: 
The timing of yellow lights on traffic signals at many intersections is purposely set to a minimum so more drivers can be ticketed for running red lights, says the 30-year-old activist group based in Waunakee, Wis.
This past summer in New Jersey , the transportation department ordered 21 cities and towns to suspend the use of red-light cameras at 63 intersections because the timing of yellow lights at those locations was below the minimum established by state law.
Other citiesâ€”including Dallas; Chattanooga, Tenn.; and Union City, Calif.â€”have been caught shortening yellow lights in the past decade as red-light cameras have become sources of steady revenue. The cameras snap photos of license plates on any vehicles in an intersection while the light is red, and citations, often carrying fines of $100 or more, are mailed to the registration’s address.
As a professional driver I can attest to the idea that yellow lights have been getting somewhat shorter lately. It shouldn’t surprise anybody that the idea of traffic enforcement has long since left the realm of safety for the less constitutional realm of an additional income stream for cash strapped cities. As the article says ;
“Cities and for-profit camera companies maximize revenue by setting yellow-light times that are too short,” said National Motorists Association President Gary Biller. “It is a violation of the public trust, and it jeopardizes motorist, cyclist, and pedestrian safety.”
Ironically, slightly longer yellow lights can significantly increase safety by allowing more time for intersections to clear, the group says. Biller cited one study that found just one additional second of yellow time can reduce the number of collisions in an intersection by 40 percent.
Just one more abuse of governmental power to contend with.
Perhaps if we are spending less money on social programs and more on roads, this kind of nonsense wouldn’t be happening? At least, it wouldn’t be happening as often.
