Annual traffic

5,602

Million motor-vehicle miles during 2025.

A measure of travel across this authority area, not the number of vehicles, a road’s daily flow or current congestion. DfT asks that these figures be rounded to the nearest million miles.

Reported injury collisions

1,268

Police-reported personal-injury collisions during 2025.

18 fatal collisions. This counts collisions, not people killed. Damage-only incidents and unreported collisions are outside this dataset.

More collisions does not automatically mean greater risk.

Traffic exposure, area size, road mix and reporting vary. These are counts, not comparable collision rates. Ask your instructor to choose practice environments suited to your current ability and current conditions.

Plan useful practice

Work with a qualified supervisor and agree goals with your instructor.

Check today’s conditions

Official roadworks, travel and weather services.

Teach and reflect

Planning, CPD and tools for instructor development.

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.
