Commercial vehicle testing is carried out by commercial vehicle roadworthy test operators authorised and supervised by the Road Safety Authority (RSA).
Since 2013, the RSA is responsible for the authorisation and supervision of the commercial vehicle testing system under the provisions of the Road Safety Authority (Commercial Vehicle Roadworthiness) Act, 2012.
Regulations under that Act, specifying the requirements and arrangements to apply for the compulsory testing of commercial vehicles, require that a person who presents a vehicle for testing presents a driving licence or passport or such photographic identification as the RSA may specify in guidelines.
The RSA is a specified body listed in Schedule 5 of the Social Welfare Consolidation Act 2005 (as amended).
From 20th May 2018, the RSA guidelines state that a driving licence, passport or Public Services Card may be accepted as a form of photographic identification by persons presenting a vehicle for testing.
I hope this clarifies the matter for the Deputy.
