Drivers parking on footpaths, cycle tracks and bus lanes will face higher fines from February 1st.
The penalty is being doubled from €40 to €80 euro by Transport Minister Eamon Ryan.
He said the increased penalty aims to encourage both active travel and a “more considerate” use of road space.“
Parking on footpaths puts vulnerable pedestrians, such as wheelchair users and those pushing buggies, at significant risk by forcing them off the footpath and into traffic,” he said.
“Parking in bus and cycle lanes endangers cyclists and undermines State investment in sustainable public transport infrastructure.“
Mr Ryan said the fine increases should help improve the safety of all vulnerable road and footpath users, by creating a more effective deterrent to these specific forms of illegal parking.
