Councils should stop doing “panic patch repairs” to potholes on roads and instead focus on keeping roads to high standards, the RAC has said.
Welsh authorities spent more than £30m paying compensation in five years after accidents caused by potholes, and filling in potholes after receiving complaints, figures show.
A Ceredigion pedestrian received over £83,000 after a fall due to a pothole.
The RAC said sorting the road out before any problems would save money.
The Welsh Local Government Association said councils had “extreme pressures” on finances and resources.
