Transportation for police forces is provided by a number of ground vehicles, aircraft and watercraft.
A police car is the description for a vehicle used by police, to assist with their duties in patrolling and responding to incidents. Typical uses of a police car include transportation for officers to reach the scene of an incident quickly, to transport criminal suspects, or to patrol an area, while providing a high visibility deterrent to crime. Some police cars are specially adapted for work on busy roads.
The first police car was a wagon run by electricity fielded on the streets of Akron, Ohio in 1899. The first operator of the police patrol wagon was Akron Police officer Louis Mueller, Sr. It could reach 16 mph (26 km/h) and travel 30 mi (48 km) before its battery needed to be recharged. The car was built by city mechanical engineer Frank Loomis. The $2,400 vehicle was equipped with electric lights, gongs and a stretcher. The car's first assignment was to pick up an intoxicated man at Main and Exchange streets.
Commonly known names to describe police cars are (police) cruiser, squad car, panda car, area car and patrol car. Depending on the configuration of the emergency lights, a police car may also be called a marked unit. In some places a police car may also be informally known as a cop car, a black and white, a cherry top, a gumball machine, or a jam sandwich, in Los Angeles, from the early 50s, until the late 70s, the lights were different from most areas, with two forward-facing, stationary red lights, with amber flashing lights facing rearward, inside of black metal housings mounted to the roof of the car.
In some areas of the world, the police car has become more widely used than police officers "walking the beat", because cars allow patrols to cover a much greater area in less time.
