Just to put things right, to be able to go faster than the speed limit the police cars have to have there blue lights activated, and the sirens flashing. I fth ecar is unmarked and dows not have any emergency equipment ie lights and sirens, then they cant speed. Some unmarked cars do have hodden lights within the bumpers and grills which light up when activated. To be fair to the cops they are entitled to food breaks and if a call comes in when they have just bought food then they have to go to it. Sometimes they might get cancelled before getting thereso turn off their sirens and lights.
just to put things right, youre talking total *******s. A police officer may drive in excess of the speed limit in the course of his duty, without engaging any warning equipment on the vehicle, however he must be able to justify his decision to do so and take on board the additional risks associated with doing so.
