As per my reply to the Deputy's previous Question, the Department of Transport shares data with Government Departments, Agencies and other bodies (including Motor Tax Offices) for the provision of services to citizens and to enable the operation of public services.
The Department of Transport only shares data where a sound legal basis exists. An effective governance framework is in place to ensure all data shared from the Department of Transport has a sound legal basis and complies with GDPR.
The volume of data shared by the Department is too large to work through on a case-by-case basis, but data shared with Government Departments, Agencies and other bodies offices may be aggregated or person specific depending on the categories of data being requested by the recipient and the legal basis for sharing.
