Under new rules introduced earlier this year, Blue Badge users must now scan a bar code at a parking kiosk and enter a vehicle registration at the Headington site. While parking is still free for disabled people, the rules have been branded 'confusing' by Oxford hospital patients and visitors. Once you have registered your Blue Badge you can drive in and and out of the hospital site for up to six months without registering again. There are two dedicated Blue Badge holder car parks: in front of the children's hospital (for west wing and children's hospital) and between the main entrance and car park 2 (for the main hospital and women's centre). ANPR has been operating at the John Radcliffe, Churchill, and NOC visitor car parks for over two years.
