Do speed display signs take photos?

[McEvangeline]

Speed display signs do not take photos. Navigation alerts about speed cameras indicate where speeding is actually monitored. Speed cameras: Speed cameras assist radar guns by capturing images only when radar detects speeding. Thus, these cameras solely photograph speeding vehicles. How traffic violation cameras work: Electronic enforcement systems use inductive loops embedded in roads to detect passing vehicles. Signals are transmitted to a central processor and cached in registers. Violation data is sent to backend systems; non-violation footage is automatically deleted after one traffic light cycle.
