Blackspot · 49 combined incidents · 1 fatal · On the M1 within 2 miles of J40
Wider area: counting every road within 3 miles — local streets, A-roads, everything — 1,310 collisions are on record, 11 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 173 of 554 UK junctions on record by recorded harm · 19 of 53 on the M1.
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.
