Since the Welsh Government introduced the 20mph speed limit in September 2023, Wales has already seen the benefits. These changes aren’t about disrupting people’s journeys; they’re about reducing harm to road users and pedestrians alike. The results speak for themselves:

• Casualties on 20mph and 30mph roads in Wales have fallen by about 25%, with 882 fewer injuries, including around 100 fewer people killed or seriously injured, in the first 18 months since the 20mph limit was introduced.
• Journey times remain largely unaffected, with most routes taking no more than two minutes longer.
• Insurers report a 20% drop in vehicle damage claims, passing savings on to drivers.

These early outcomes show that marginally slower speeds are saving lives, reducing injuries, and creating safer roads across Wales.
