Restrict blanket 20mph speed limits on major and strategic roads.

Background

Prevent councils from putting blanket 20mph limits on major and red routes. Force them to use evidence-based limits, robustly justify changes, and review roads with poor compliance.

Additional details

We support 20mph limits outside schools, in busy residential areas, and where there is a genuine safety concern. However, blanket limits on wider main roads and red routes do not reflect the road design. ​When speed limits feel unreasonable, it damages public respect for them overall, risking lower compliance in areas where slower speeds are truly vital for safety. Speed limits must be based on road conditions and clear evidence, not blanket policies.
