Police cars are driven by policemen and are used on patrol. They appeared in various magazines stories and later the television series.
In the magazines, the police cars are loosely based on a 1930s or 1940s Wolseley or Riley saloon. In the television series, the police cars are modified from Taxis and as a result are based on Austin London Taxis of 1936.
The police cars are painted either purple or blue with 'POLICE' and two stripes painted on the sides in white. They have blue sirens on top of them.
