A vehicle travelling at 137km/h in a 120 km/h Zone on the M4 in Meath and a car going 135km/h in a 100 km/h Zone on the N7 at Brownsbarn in Dublin are among the detections made during National Slow Down Day.
The 24-hour road safety campaign began at 7am and saw more than 77,000 vehicles checked within the first five hours.
A total of 138 speeding offences were detected in that period.
Here in Cork excessive speed detections were made on at Ballyvergan East in Youghal amd on the N25 at Ballyadam in Carrigtwohill
Rural roads are being particularly targetted as almost four out of five road fatalities so far this year have occurred on roads where an 80 kilometre per hour speed limit applies.
Speaking to RedFM News Sam Waide from the Road Safety Authority says a concerning trend is emerging on rural roads:
"Four out of five of those fatalities have happened, rural roads are not roads which are 80 kilometres and higher. So, it is really important that for people not only to be reminded of the stark reality the risks and the dangers that people cause if they, if they speed excessively or in appropriately."
