Industry and Employment Correspondent The Road Safety Authority has admitted that 484 driving tests were cancelled last week for weather related reasons including unsafe conditions, ice and snow at test centres. However, it has categorically rejected claims that driving tests were being "arbitrarily" cancelled due to low temperatures - but said any customers whose tests were affected by adverse weather conditions will be offered a re-test free of charge. Earlier, the Unite trade union, which represents around 85 mainly self-employed driving instructors, accused the RSA of cancelling driving tests because the weather is too cold - at a time when essential workers are unable to secure tests due to backlogs.
