The provision of a primary medical certificate is based on a professional clinical determination by the Senior Medical Officer for the relevant local Health Service Executive. To qualify for a primary medical certificate an applicant must be permanently and severely disabled within the terms of the Disabled Drivers and Disabled Passengers (Tax Concessions) Regulations 1994.
An unsuccessful applicant can appeal the decision of the Senior Medical Officer to the Disabled Drivers Medical Board of Appeal. The Medical Board of Appeal is independent in the exercise of its functions to ensure the integrity of its clinical determinations.
