Sources and matching
Traffic: DfT road traffic downloads. Collisions: DfT STATS19 2025. We match the traffic authority code to the collision’s current highway-authority code; this does not assign an instructor or test centre to that area. Local traffic estimates are less robust than regional totals. Download the source metadata and full history.
