A council in East Sussex has proposed a policy to make 20mph the top speed on roads being built in new housing developments.
Rother District Council (RDC) said if approved, it would require developers to design roads in such a way that 20mph would be the maximum speed at which it was possible to drive.
It said pedestrian safety and community wellbeing were the focus behind the new proposal.
At a full council meeting, RDC unanimously agreed to consult on the road safety plan, following a notice of motion submitted by councillor Kathryn Field.
