Concerns over water running across the road at Sithney Common Hill were raised at the last meeting of Helston Town Council.
Councillor Ronnie Williams said the car wash in the lay-by often left water running down over the road.
“It’s not a problem until we get icy weather and then it freezes,” he said. If someone loses their life it’s too late.”
PC Anne Butcher, from Helston Police Station, agreed to look into it.
