Wales plans to lower speed limits to 20mph (32km/h) on dozens of additional residential roads. The default limit in built-up areas dropped from 30mph (48km/h) in September 2023, a shift campaigners credit with preventing nearly 900 injuries.
Background on Policy Shifts
The initial rollout sparked backlash due to its £34m cost, prompting reversals to 30mph on select roads in 2024. Now, authorities review numerous routes and have released a list of potential adjustment sites.
Proposed Speed Limit Adjustments
The Welsh government outlines changes to certain 20mph and 30mph limits on trunk roads. It also explores buffer zones—brief road segments near 20mph or 30mph areas—to enable smoother deceleration.
For instance, drivers approaching a 20mph zone from 60mph (96km/h) speeds could encounter a temporary 40mph (64km/h) buffer.
Implementation Process
All modifications require Traffic Regulation Orders (TROs), which typically take nine months to enact. Changes may not take effect until 2027. Residents can submit objections once draft TROs appear.
