Gardaí found 1,286 motorists driving over the speed limit during National Slow Down Day, which ran for 24-hours yesterday.
In Limerick, a motorist was detected driving at 166km/h in a 100km/h zone on the N21 in Adare.
While in Waterford, a motorist was detected driving at 95km/h in a 50 km/h zone on the R680 Cork Road.
Other examples of the breaking of speed limits included a motorist detected doing 98km/h in a 60km/h zone on the R147 Dunboyne, Co Meath, and another motorist detected driving at 105km/h in an 80km/h zone on the R265 St Johnston, Co Donegal.
Gardaí said that the numbers represented an increase in speeding detections from the previous operation in February.
"This is disappointing evidence that some drivers continue to ignore speed limits despite widespread public commentary and coverage regarding safety on our roads," a spokesperson said.
"An Garda Síochána is reiterating to motorists that road safety is a shared responsibility and everyone has a personal responsibility to slow down and exercise caution when travelling on our road network."
Throughout this National #Slowdown Day, we detected a total of 1,286 vehicles travelling in excess of the speed limit.
