Gardai will be able to fine people making non-essential cross-border trips from Monday.
From 7 am on Monday Gardai will be able to financially penalise anyone travelling from the north into the republic for a non-essential reason.
It means any residents in the North caught here without a valid reason can be fined 100 euro.
Gardaí are warning that if the driver of a car has two adult passengers with them then each of the three adults in the car will be penalised.
Meanwhile, over the past seven days Gardaí have issued around 375 Fixed Payment Notice at Dublin Airport to people going abroad for non-essential reasons.
300 house party related fines ranging from 150 to 500 euro have also been handed out.
So far, more than 3,500 people have been handed fines for travelling outside their 5km limit.
Six people will appear in court next month after failing to pay Covid-19 fines within the required 28-day timeframe.
