People who exceed the limit will get 3 penalty points.
Motorists are being advised about a new speed camera which will come into operation next week.
A 'Motorway Average Speed Safety Camera' will be in place in Co. Tipperary.
The camera monitor the average speed of a vehicle between two points, with an €80 fine and 3 penalty points for those exceeding the limit.
Although there's been a similar camera in place in the Dublin Port Tunnel, it's the first time one will be deployed on an Irish motorway.
Motoring and Transport Commentator Conor Faughnan isn't sure it will work:
