Interesting how they had a straight red light bar. Here in Delaware, the different light bars mean different things: Red and Blue: Police Red: Fire Department/ambulance Red and Yellow: Ambulance Blue: Fire Police (Not to be confused with Fire Marshal. They are two different jobs here. Fire Marshal investigates fires, enforces fire codes, etc, whereas fire police do traffic control, crowd control, and act as police on a fire scene). I know some states blue indicates general police just like the red and blue does.
