Nearly 3 thousand drivers were caught speeding over the bank holiday weekend.
Gardaí also issued fines to over 200 people for driving while using a mobile phone, and more than 70 people for driving without a seatbelt.
A motorist who was clocked driving at 179km/h in a 60km/h zone, was one of 2,800 drivers detected speeding over the Easter weekend.
Speed checks were carried out across the country between 7am last Thursday and 7am this morning.
In Co Meath, a motorist was detected travelling at 139km/h in a 80km/h zone in Dunboyne, with another detected doing 125km/h in a 50 Km/h zone at Milltown Castlepollard, in Co Westmeath.
In Dublin, a motorist was detected travelling at 110km/h in a 50 Km/h zone on the Naas Road.
Three people, including a four-year-old boy, died on the country's roads, with 12 people receiving serious injuries in 11 road collisions.
Gardaí said over 4,500 breath tests and 213 oral fluid tests were carried out at checkpoints over the weekend, with 149 arrests for driving under the influence of an intoxicant.
225 motorists were found to be using a mobile phone while driving, with 73 motorists issued with a Fixed Charge notice for not wearing a seatbelt.
Gardaí also said that 160 unaccompanied learner drivers were detected, with 109 vehicles seized from learner permit holders driving unaccompanied.
They added that 438 vehicles were seized for having no tax or insurance.
So far this year 51 people have died on Irish roads, according to garda figures.
Assistant Commissioner for Roads Policing and Community Engagement Paula Hilman said education and enforcement remain vital in terms of road safety messaging.
Speaking at a road safety event at the University of Limerick, she said: "I think it's important to emphasise that the majority of people drive safely, but for those who don't, we will be out on the road, enforcing and visible on the roads."
Ms Hilman said one in three people who have lost their lives on the roads this year were under 30 years of age.
The Assistant Commissioner said An Garda Síochána would continue to collaborate with all partners on the Road Safety Partnership Board, with the Road Safety Authority and the Department of Transport and Department of Justice.
Asked whether punishment measures were sufficient to deter reckless driver behaviour, she said these issues are a matter for legislators and for the courts.
"We welcome anything that will reduce death and serious injury in our roads and there are certain issues like this legislatively that the Department of Transport, are looking at and I'm sure the relevant ministers will be bringing those forward."
Meanwhile, Three boys have been arrested after what Gardaí are calling a "managed containment operation."
Officers received reports of a vehicle driving dangerously on a national road in Dublin yesterday.
An operation to stop the vehicle was put in place - it stopped on the M7 in the Kildare area.
Three boys in their teens were arrested - one has been charged and has appeared before the children's court today.
