Plans to extend 20mph speed limits to more roads across Wales could see further changes in North Wales, including new buffer zones on the A470 at Llanrwst and Betws-y-Coed.
The Welsh Government has confirmed it is reviewing dozens of roads on the trunk road network where speed limits may be adjusted. The move follows the nationwide reduction of the default speed limit in built-up areas from 30mph to 20mph in September 2023 — a policy that proved controversial but which ministers say has delivered safety benefits.
Campaigners previously claimed the change resulted in almost 900 fewer injuries across Wales. However, the £34 million rollout sparked a public backlash, prompting a review in 2024 that led to some roads reverting to 30mph where 20mph was deemed unsuitable.
Now, ministers say further refinements are being considered, including the introduction of buffer speed limits designed to help drivers slow down more gradually when approaching lower limits.
In North Wales, buffer zones are proposed on the north side of the 20mph limit on the A470 at Llanrwst and on the north side of the 20mph limit on the A470 near its junction with the A5 at Betws-y-Coed.
These stretches would introduce a short 40mph section between higher-speed rural roads and the 20mph village limits, aiming to improve compliance and safety.
The Welsh Government said buffer zones could be used where drivers currently transition directly from 60mph rural roads into 20mph areas. By stepping speeds down gradually, officials hope to make the limits clearer and easier to follow.
All proposed changes will require Traffic Regulation Orders, a legal process that can take up to nine months. That means any confirmed changes are unlikely to come into force before 2027. Residents and road users will have the opportunity to object when draft orders are published.
The 20mph policy has had a particular impact in North Wales, where many communities sit along major through-routes such as the A470 and A5. In towns and villages including Conwy, Llandudno Junction, Bangor and Wrexham, drivers have had to adjust to lower limits through residential and town-centre areas.
Supporters argue the reductions have made streets safer for pedestrians and cyclists, particularly near schools and residential estates. Critics, however, have questioned enforcement, journey times and the suitability of some routes.
With further reviews now under way, North Wales motorists could see additional speed changes over the coming years — as the Welsh Government continues to balance road safety goals with public opinion and practical road use.
