I am keenly aware of the utmost importance of ensuring the safety of small public service vehicle (SPSV) drivers. However, I should explain that matters of a criminal nature, as well as enforcement in relation to those, are for my colleague, the Minister for Justice and Equality. As assault is a criminal matter, it can only be investigated by members of An Garda Síochána.
The regulation of the SPSV industry, including the regulation of passenger behaviour, is a matter for the National Transport Authority (NTA) under the provisions of the Taxi Regulation Act 2013 and I currently have no proposals for amending that legislation in this regard. Given your reference to signage, and in line with the NTA's power in this regard, I have forwarded your correspondence to the Authority for further consideration and direct reply if appropriate.
