Suisun City, California Speed Traps

Car or Motorcycle Cop sits just below the mini overpass once you see him and you’re speeding it’s too late.

CHP on bikes hiding around corner after first 2 turns. There will be a 45mph sign after the 2nd turn and the trap is right after it.

Traveling west on Railroad Ave. a black&white sits at corner of Marina & Railroad just as you come around the curve. Its Radar.

A school bus was placed at the side of the street well away from the normal school bus route with the sign out and flashing lights. No driver no kids and the police officer was sitting behind the bus. The officer would pull a person over and give them a ticket and while in the process the sign would still be out and flashing with people driving on by. Once the officer was done he would turn around and get back behind the bus again. Is this legal?
