New regulations covering the National Car Test are taking effect from today.
The changes include free re-tests in cases where defective tyres are the only cause of failure, as well as a relaxation of the rules governing registration lights and indicators.
Free registration-plate stickers with the relevant county name in Irish will also be provided, while a new pre-payment system for internet bookings has been set up and a new centre will also be opened in Inishowen.
The changes follow a review of the contract for the NCT service which found that targets for its first five years had been met or exceeded.
