Five streets off the B1332 Bungay Road, in Poringland, south of Norwich, became subject to the restriction on Monday (April 20).

The streets which covered by the 20mph limit are Crown Close, Paddocks Way, St Wandrille Close, Tas Road and Wood Lane - all within the Milestones development.

The council says the speed limit would improve safety on the development.

Signs are already in place but a traffic regulation order needed to be confirmed, following consultation last year.

it is not unusual for new housing developments to have 20mph signs put in place before the traffic orders to make them enforceable are obtained.

Department for Transport guidance is that 20mph zones and 20mph speed limits should be "generally self-enforcing", given road conditions and measures such as signs and traffic calming.

Norfolk Police has previously said it does not routinely enforce 20mph limits and zones.

But the force has said it will do so if "clear evidence of significant non-compliance or injury collision history supports such action".
