The light always goes from green to red in less than 5 seconds for east and west traffic flow. This is illegal and dangerous for traffic.

The amber time on signals is set based on the speed limit of roads. The standard for 40mph roads is actually 3.9 seconds, based on a safe stopping rate. 25mph and 30mph roads are 3.5 seconds of amber, 35mph is 3.6 seconds, 45mph is 4.3 seconds, 50mph is 4.7 seconds, and 55mph is 5.0 seconds. The "all red" interval that follows the amber light is based on the size of the intersection and the speed limit, ranging anywhere from 1.0 seconds to a maximum of 2.5 seconds.
This standard is for new signal timings only. If the timing was done before the standard was put in place, the yellow time would have been 4.8 seconds.
