Data released by the Welsh Government reveals there were 668 reported collisions between January and March, up 5% on the same period in 2024 but 9% lower than in 2023, before the 20mph law came into force. Fatal crashes fell slightly, from 19 last year to 16 this year.
Overall, 897 people were injured, including 250 seriously. That’s 6% more than in 2024, but still 7% fewer than two years ago. Of these casualties, 16 (2%) were killed, 250 (28%) people were seriously injured, and 631 (70%) had slight injuries.
On roads restricted to 20 and 30mph, collisions were virtually unchanged compared with last year – but casualties rose by 3%. Fatalities fell slightly, from seven to six.
When it comes to the number of crashes, there were 668 police reported road collisions in Wales in this year’s first quarter. Of these collisions, 15 (2%) were fatal, 220 (33%) were serious, and 433 (65%) were slight.
The figures come as Welsh councils begin reverting some 20mph roads back to 30mph following new government guidance. These changes, however, were not in place when the data was collected.
The 20mph law, introduced in September 2023, has split opinion across Wales. Supporters say it has saved lives, while critics argue it has caused frustration and slowed travel.
What is clear from the latest figures is that, while crashes have crept up from last year, roads remain safer than before the limit was introduced.
