While this is an operational matter for the Road Safety Authority, who have responsibility for the operation of the driver testing service, I understand that an extra 10 temporary test centres have been opened. In almost all cases these new locations are close to existing test centres and are effectively an expansion of existing locations or replacing an unsuitable location.
A further 9 locations have been expanded within the existing premises to accommodate more testers. They are needed because there is not adequate space in existing centres to accommodate many of the additional driver testers and comply with social distancing requirements.
