Gardai have been conducting speeding spot checks as part of a 24-hour Operation Slowdown initiative, supported by the Road Safety Authority and other stakeholders.
A total of 5,062 vehicles were checked this morning and 68 were detected as over the speed limit.
One car was travelling at 87km/h in a 50k zone on the R118 Rock Road in Dublin 4 Dublin while another vehicle was detected travelling at 77km/h in a 60k zone on the M7 Lewistown at Naas, Co Kildare.
The aim of "Slow Down day” is to remind drivers of the dangers of speeding, increase compliance with speed limits and act as a deterrent to driving at excessive or inappropriate speed.
The public has been reminded that excessive or inappropriate speeding is a major factor in road traffic collisions. Safety cameras will be on the roads all across Ireland where fatal or injury collisions are happening as a result of inappropriate speed.
