More than 900 motorists were caught speeding on the first National Slow Down Day of the year.
Three drivers were arrested on suspicion of dangerous driving, with three more arrested on suspicion of driving while intoxicated.
The proactive 24-hour operation which began on Thursday morning was rolled out amid a significant rise in road deaths in Ireland.
One of the more than 900 motorists detected driving in excess of the speed limit was travelling at 160km/h in a 100km/h zone in Co Kildare.
All of those drivers caught will now receive a €160 fixed charge notice in the post and have three penalty points applied to their licences.
Road deaths are continuing to rise this year – 37 people have died on roads in the Republic so far in 2024, five more than last year.
Road traffic collision figures for 2023 showed that the number of road deaths increased by 19 per cent compared with 2022.
A total of 184 people died in 173 fatal collisions in 2023, compared with 155 deaths in 149 collisions in 2022.
Earlier this week, Minister for Justice Helen McEntee said the number of road deaths this year was “far too high.”
“I had hoped that we would see a decrease and unfortunately it’s going in the opposite direction,” she said.
“I think we’re experiencing a very difficult patch at the moment. It often takes time to reverse trends as they start to emerge, but every effort is being made.”
She said gardaí were focused on reducing the number of road crashes and fatalities.
“We are seeing continued trends, when it comes to collisions, when it comes to serious accidents. It’s around speeding, it’s around drink driving and drug driving and perhaps now to a lesser extent people on their phones and not wearing seatbelts,” the Fine Gael Minister added.
According to the Minister, of the 8,000 drivers stopped by gardaí last year, 35 per cent of people were detected to have drugs in their system.
“What gardaí are doing now is that they’re looking at the times of the day when they need to be on the roads,” she said.
“They’re looking at the types of roads where accidents are happening and, in fact, many of those checks are being conducted by gardaí who are not on the Roads Policing Unit.
“About 75 per cent of drug and alcohol testing is carried out by the frontline gardaí, so we can focus in on figures of the roads policing units and say they’re slightly down, which they are, but so much of the work is being done to try and deal with this issue.”
It comes as Garda Commissioner Drew Harris earlier this week said that people who are scrolling through social media while driving is a “real issue”.
