The Road Traffic (Traffic and Parking) Regulations 1997 (as amended) provide that, where traffic sign number RUS 015 is erected at the entrance to a road, a driver of a vehicle exceeding the gross design weight specified on that sign shall not proceed on that road.
As Minister for Transport, I have no role in the practical implementation of road weight restrictions, as decisions on the location and introduction of restrictions fall to the relevant road authority. The Deputy may wish to contact Dublin City Council for details of that authority's HGV management scheme.
