A yellow traffic light means to slow down or stop completely. When the light is yellow it is about to change to red in a few seconds. Contrary to popular belief by many drivers yellow does not mean speed up.
The national standard for yellow lights is to allow one second for each 10 mph of the posted speed limit. So in a 55 mph posted zone, the yellow light should last at least 5.5 seconds. Recently a number of cities have been busted for shortening the yellow light times and collecting millions of dollars in fines for running red lights.
they both travel at the same speed ? :>)
