Paisley would be the first area to receive new 20mph limits under proposals for a phased rollout across residential roads in Renfrewshire.
The programme is estimated to cost £1.85m. A start date has not been set, with discussions continuing over funding from Transport Scotland.
Renfrewshire Council’s Infrastructure, Land and Environment Policy Board will consider the report on Wednesday, 4th November 2026.
Johnstone, Elderslie, Brookfield and Kilbarchan would follow three months after the Paisley launch. Renfrew would be included at six months.
Inchinnan, Erskine, Bishopton and Langbank would follow at nine months. Howwood, Houston, Crosslee, Bridge of Weir and Lochwinnoch would be included at 12 months.
Officers used vehicle speed and collision data to prioritise the areas presenting the greatest road safety risk.
Each phase would be introduced through an 18-month temporary traffic order. Residents would be invited to give feedback during the first 12 months.
That feedback and observed vehicle speeds would help determine whether the limits should be made permanent, changed or partly or fully returned to 30mph.
Any permanent traffic order would have a further 28-day public consultation before returning to the board for a decision.
The full programme is expected to take two and a half years, including the process for making limits permanent.
The initial implementation estimate was £4m. Further assessment of the road network and signs has reduced that estimate to £1.85m.
Existing signposts and street lighting columns would be reused where possible. The proposed limits would be marked by signs, without corresponding road markings.
Councillors are being asked to approve the phased approach, subject to confirmation of Transport Scotland funding.
