Before the camera authorization expired here in VA, there were two types, the state-controlled red-light cameras and the city-controlled ones (e.g. City of Fairfax). The state lights were set by state engineers and had normal yellows. The cities did whatever they felt like. One city light in Fairfax City (Fairfax Circle) was changed from a staggered light to clear through traffic to a simultaneous, shortened yellow. You better believe VA legislators heard from people like me and now there are no more red light cameras, mainly because they were abused for revenue generation purposes.
> a simultaneous, shortened yellow....
I thought that would trip the conflict monitor and start flashing red in all directions?
