Road collisions and casualties across Wales have continued to fall, with new figures showing a reduction on roads with 20mph and 30mph speed limits.
Figures for April to June 2026 show collisions across all Welsh roads fell by 19 per cent compared with the same period last year, while casualties dropped by 20 per cent.
On roads with 20mph and 30mph speed limits, collisions fell by 22 per cent and casualties by 20 per cent.
Compared with the same period in 2023, before the default 20mph limit was introduced, collisions on those roads have fallen by 37 per cent, with casualties down by 35 per cent.
The figures are the lowest recorded for these comparisons, excluding data gathered during the Covid pandemic.
Deputy Minister for Transport Mark Hooper has welcomed the figures, saying they provide “more evidence that the 20mph default speed limit is helping to make our roads safer”.
He added: “Every one of those figures represents someone who has avoided injury, or death, on our roads.”
Mr Hooper said the Welsh Government would continue to monitor the figures as part of its ongoing evaluation of the policy.
