The items to be tested, the method of testing and the reasons for refusal of a NCT certificate are set out in the national car test manual 2004, which is published by my Department. The NCT includes a check to ensure there is an adequate view from the driving seat and that it is not interfered with by objects or stickers on or in the vicinity of the windscreen. The presence of an object or sticker in the direct line of vision of the driver which would prevent the driver having an adequate view would constitute a reason for refusal of an NCT test certificate.
A person dissatisfied with the outcome of a NCT may appeal the decision under the complaints and appeals procedure operated by the National Car Testing Service Limited, NCTS. It is also open to a car owner to appeal a decision of NCTS to refuse a test certificate to the District Court.
