A major council has put forward plans to effectively hardwire 20mph speed limits into every future housing development, in a bid to improve safety.
Rother District Council in East Sussex has unanimously agreed to consult on a proposal that would require all newly built residential roads to be designed so that 20mph is the maximum speed drivers can realistically reach.
Rather than simply posting new speed limit signs, developers would be required to shape roads themselves, through narrower carriageways, tighter junctions, and traffic-calming features – to ensure that higher speeds are impossible.
Council leaders said the lower speed limits aimed to protect pedestrians, cyclists and families moving into new neighbourhoods.
But opponents argued the policy represents yet another attempt by local authorities to micromanage how people travel.
The proposal was backed at a recent full council meeting following a notice of motion submitted by Kathryn Field, the authority’s portfolio holder for the environment.
According to the council, lower vehicle speeds in residential areas significantly reduce the severity of accidents, encourage walking and cycling, and help foster “community cohesion and individual wellbeing”.
Ms Field said the move was about setting the tone for new communities from the very beginning.

PA/GETTY“By requiring housing developers to design their roads with low traffic speeds, we’re planting the seeds for safer, more inclusive communities,” she said.
“If agreed, this step will protect families, support healthier travel options, and create environments where people feel comfortable getting around on foot or by bike.”
The proposal would apply only to new housing developments, not existing roads. However, critics say it signals a wider shift in thinking that prioritises social engineering over convenience for drivers.
Across the UK, 20mph zones have proven deeply divisive. Supporters argue they save lives and reduce noise and pollution, while opponents warn they slow journeys unnecessarily, frustrate drivers and are often poorly enforced.

While Rother‘s plan stops short of imposing new limits on existing streets, some residents fear it could be a stepping stone toward wider restrictions in future.
The council insisted the policy is firmly focused on new developments, where road design can be shaped from the outset rather than retrofitted later at public expense.
If approved following consultation, the approach would be written into upcoming planning policies, including a proposed rule known as Policy LWL7.

PACouncil officers would then work alongside developers and local community groups to ensure the policy is delivered effectively.
Supporters argued that designing safer streets from day one will reduce long-term costs associated with road accidents, enforcement and retroactive traffic calming.
They also point to changing attitudes among younger families, many of whom want quieter streets where children can walk or cycle safely.
But sceptics warn that imposing design restrictions on developers could push up building costs at a time when the country is already struggling with housing supply. The consultation process will now give residents, developers and stakeholders the chance to have their say before any final decision is made.
