If it is actually 2 seconds, you have a strong case in court. The ITE has a bottom limit of 3 seconds for small intersections in low speed locations.

“If it is actually 2 seconds, you have a strong case in court.”
There have been numerous instances where the contractor responsible for managing the cameras decrease the time on yellow. Their contracts generally include profit sharing and if there are not adequate tickets handed out they lose money.
Some people in Dallas went to the trouble to time the lights in order to monitor the city. Apparently even after the city knew the yellow time was too short they took no action.
