The regulation of the small public service vehicle (SPSV) sector is the responsibility of the National Transport Authority (NTA) under the provisions of the Taxi Regulation Act 2013.
Under the 2013 Act the NTA may make regulations for SPSVs and their drivers and may set different requirements and conditions in relation to the licensing and operation of different categories of SPSVs and their drivers.
I am advised that the NTA has made a determination against introducing a licensing category to cover specialist tourism vehicles that would include the type referred to.
