The Commission for Taxi Regulation (also An Coimisiún Um Rialáil Tacsaithe and Taxi Regulator) was a public body in Ireland that existed between 2004 and 2011 regulating small public service vehicles (SPSVs) - the generic term for taxis, wheelchair accessible taxis, hackneys and limousines. Taxis and wheelchair-accessible taxis are allowed to pick up passengers in the street or at a stand and have their fares calculated by a meter; hackneys and limousines do not use meters and are not permitted to pick up passengers in the street or at a stand.
