Gardaí mounted an intensive operation in the uplands of Wicklow to stop people going there to exercise and view the snowy conditions, despite the 5km from home rule in place.
Vehicles were also being towed away for illegal parking and blocking access.
A network of checkpoints was put in place and people were being turned away from the uplands, while several towing trucks had been deployed by the Garda to tow vehicles away on Sunday.
Cars towed away and taken to a pound are released to drivers after a €150 fine has been paid. If the vehicles are not collected and the fee paid on the day of towing, an additional charge of €50 per day applies.
