For six seasons the show followed officers in the Thames Valley, but moved to Devon and Cornwall for the last series in 2009.

Lee Boardman narrated the show until the second half of series 7, employing a light-hearted and pun-intended approach.

[3] From Series 7, the show moved on to follow the Road Crime Unit and the front line Dog Squad of Devon and Cornwall Police.

The Road Crime Unit operates marked BMW 3 Series along with unmarked 2.5L Ford Focus STs.

In a special two part series called Road Wars USA, Andy Samuels[4] and Chris Piggott spent a couple of months attached to a Gang Unit in Cicero, Illinois, near Chicago, to note how law enforcement is practised in the United States.

On 5 December 2017, an on-duty policeman PC James Dixon, who appeared in the show was killed in a motorcycle collision along with a 91-year old woman on the A4 road in Wargrave, Berkshire.
