Traffic and parking controls are applied generally through the application of traffic and parking by-laws or temporary rules made by the Garda Commissioner with my consent under sections 89 and 90 of the Road Traffic Act, 1961, or through general traffic regulations made by me under section 60 of the Road Traffic Act, 1968. The question of applying restrictions on the parking of large vehicles in urban areas is being considered by the Garda Síochána in the context of temporary rules to apply initially in the Dublin area. This approach follows from discussions between my Department, the Garda Síochána and Dublin Corporation. The position relating to the preparation of the appropriate temporary rules and other related matters was set out in the reply to Question No. 136 of 26 November 1991.
