The Welsh Senedd recently rejected a motion from Reform UK to abolish the default 20mph speed limits. The proposal was defeated by a vote of 51 to 37, despite arguments from Reform UK that the policy has resulted in wasted public funds due to the cost of replacing signage. During the debate, Transport Minister Mark Hooper defended the measure as “fundamentally the right policy,” citing a decrease in casualties on such roads.

Subsequent provisional police data from the second quarter of 2026 indicates a significant reduction in road accidents. Casualties on roads with 20mph and 30mph limits fell by 35% compared to the same period in 2023. Additionally, collisions on these specific roads decreased by 37%. The Welsh Government noted these figures represent some of the lowest recorded levels for these road types outside of the Covid pandemic period.
