Hundreds of people have been fined after being caught more than 5km from home over the weekend.

Many more were given cautions and sent home after being stopped at Garda checkpoints, as the force ramped up enforcement of the Public Health Act.

Gardai had only issued 37 on-the-spot fines of 100 euro under their new Public Heath Act powers up to Thursday.

But it's becoming clear that then there's been a massive increase in the number of people ticketed  -- so many, in fact, that Garda Headquarters is still counting them all.

More than 30 were ticketed at just one checkpoint at Newcastle Woods in Co Roscommon on Sunday, and seventy other drivers given a warning.

In Co Wicklow alone, more than 170 people were fined – over 100 on Saturday, and at least 70 more on Sunday -- with four hundred drivers sent home with a caution.

It's understood similar levels of enforcement have taken place in all parts of the country.
