Blackspot · 85 combined incidents · On the M25 within 2 miles of J17
Wider area: counting every road within 3 miles — local streets, A-roads, everything — 383 collisions are on record, 1 of them fatal. That figure tracks how built-up the area is rather than the road, so it is context only and the score below does not use it.
Ranked 136 of 554 UK junctions on record by recorded harm · 20 of 33 on the M25.
A ranking of our own records, not a risk-per-vehicle measure and not an official safety assessment. Collisions are weighted by outcome: one fatal counts for 50 slight collisions, one serious for 8.
