The Disabled Drivers and Disabled Passengers (Tax Concessions) Scheme provides relief from VAT and Vehicle Registration Tax (up to a certain limit), and exemption from motor tax, on the purchase of an adapted car for transport of a person with specific severe and permanent physical disabilities. The disability criteria for these concessions are set out in the Disabled Drivers and Disabled Passengers (Tax Concessions) Regulations 1994. To get a Primary Medical Certificate, an applicant must be permanently and severely disabled within the terms of these Regulations. I have no plans to change the criteria at this stage.
