An Incident Response Vehicle, shortened as IRV, is a general patrol car used by the Metropolitan Police and in The Bill. They are used by people with the standard police license. In the past they have been previous generations of the Vauxhall Astra & the Ford Focus. They first replaced the Rover Metro Panda Cars in 1996, which had been used since the early 1990s, and were replaced by Ford Fiestas in 2002, but Astra Mk3 and Focus IRVs were still used alongside them, and once again replaced the Fiestas in 2004 with new Mk4 Astras, and later Mk5 Astras until the shows end in 2010.
