M42 J7 — Blackspot analysis Castle Bromwich & Marston Green

Warning Zone · 41 combined incidents · On the M42 within 2 miles of J7

Wider area: counting every road within 3 miles — local streets, A-roads, everything — 846 collisions are on record, 13 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.
