Two people have died in two separate collisions in the last 24 hours, and 283 have been caught speeding so far this bank holiday weekend.
A man, aged in his 50s, died after he was struck by a lorry in Dublin city centre on Friday afternoon, and a second man in Sligo, aged in his 20s, died after the car he was driving crashed on Saturday morning.
Gardaí have been out detecting poor driving behaviours since 7am on Friday, and since then, they have checked almost 127,176 vehicles.
While the majority of motorists are "travelling within the designated speed" some of those detected above the limit have been "especially dangerous."
Some notable detections include a motorist travelling at 86km/h in a 50km/h zone in Clara, Co Offaly, and a motorist travelling at 146km/h in an 80km/h zone in Oranmore, Co Galway.
Elsewhere, one motorist in Donegal was caught driving 95km/h in a 60km/h zone on the N13 near Carrowreagh, Bridge End, and another detected was 57km/h over the speed limit on the R238 near Quigleys Point, also in Donegal.
Commenting on these detections, Chief Superintendent, Jane Humphries said: "Our October bank holiday roads policing operation has been underway since first thing Thursday morning and while we are generally seeing good levels of compliance with speed limits on roads around Ireland, I am gravely concerned by the risks taken by some drivers and the two fatal road traffic collisions.
"Please slow down and drive safely today and over the rest of the long weekend as so many of us take to the roads.”
