The junctions Britain hasn't fixed: 12 locations were collision hotspots in every one of the last five years
New 2025 collision data confirms a stubborn pattern: a dozen junctions — eleven in London, one in Oxford — have recorded repeat collisions every year since 2021, led by Mitcham Road in Furzedown with 56.
Five years, same junctions
Our analysis of five years of police-reported collision records (2021–2025, over 500,000 collisions) identifies twelve locations that qualified as collision hotspots in every single year. Mitcham Road in Furzedown, south London, leads with 56 collisions and 67 casualties across the period; The Plain in Oxford is the only location outside the capital.
A junction that produces multiple collisions year after year is not bad luck — it is a road-layout problem that hasn't been fixed. The 2025 data, the first full police-validated year to be published, shows none of the twelve has improved materially.
The national trend
Great Britain recorded 101,525 police-reported collisions in 2025, up slightly on 2024's 100,927 but below the 2022 peak. Our interactive map covers every hotspot nationally and for 37 towns and cities, with the data free to download.
