Traffic light on NE bound Castro downtown area just before the Railroad tracks (no cross street), which used to be blinking red light so car could stop, then proceed to Central Expressway (a few car lengths) traffic light, then turn right on red. Two officers standing and going up to driver’s windows, asking them to turn right at Castro. It really isn’t a detour R on Central due to a public safety issue, they are asking people to pull over on Central so can give Red Light Violation. At the light before the RR track, the only warning is a smallish sign with arrow: “Stop Here on Red”. Note further south on Central, there is a sign before the next traffic light: “Red Light Violation $366″ [sic]” Research: ticket may cost $490.
