A new average speed camera system is now in operation on the N2 in Co Meath.
The static cameras are located at Ballymagarvey and Cullen (near The Brink), just south of Slane.
Motorists detected driving in excess of the 100km/h limit between the two speed cameras will now be subject to prosecution.
The cameras are located roughly 8km apart on the N2 and a driver's average speed between the two points will be taken to decide if they have broken the speed limit or not.
The system uses automatic number plate recognition technology to record the time and date of each vehicle as it passes each of the two cameras.
Anyone found to be driving in excess of the limit will be issued with a fixed charge notice, which carries three penalty points and includes a €160 fine.
The fine increases to €240 if it is not paid within 28 days while on a court conviction, a motorist will get five penalty points and can be fined up to €1,000.
The new average speed camera system is intended to slow traffic on the N2 approach to Slane Village.
In December 2023, local residents erected 23 crosses on the wall of Slane Bridge to commemorate the 23 lives that had been lost on the stretch of road, which has a particularly steep gradient.
Similar systems are already in place in other parts of the country, including sections of the N3 in Co Cavan, the N5 in Co Mayo, the M7 in Co Tipperary and in the Dublin Port Tunnel.
Today marks the first time a new average speed camera system has gone live since gardaí announced that motorists were to have their fines and penalty points expunged after a static speed camera on the N17 in Co Mayo was found not to be certified.
As a result, gardaí said more than 1,800 fixed charge notices issued between 20 December 2024 and 12 February 2025 are to be revoked.
Gardaí also said that the camera has since been certified and the system on the N17 near Claremorris has been operational again since 14 February.
A static speed camera differs from an average speed camera system as it is only measures a motorist's speed at one particular point along the road.
Static speed cameras and average speed camera systems are in operation in addition to the 58 mobile speed vans operated by GoSafe that operate in over 1,500 safety camera zones nationwide.
