A range of comprehensive measures is in place to prevent the abuse of the DVLA database. Parking companies cannot obtain data from the DVLA unless they are members of an appropriate accredited trade association and abide by its code of practice. In this role, the British Parking Association audits its members annually, and the DVLA also undertakes regular inspections. When necessary, the DVLA takes direct action to suspend facilities to request vehicle keeper data. In 2012, the DVLA suspended 21 parking companies from receiving that information.
