The chart counts the whole road as it was each year, so new or renumbered stretches move it. The percentage changes compare only count points present in both years (55.9% of today’s road for 2019). In 2025, 1 of the 6 count points were counted; DfT estimated the rest from earlier counts and local trends.
A4300 collisions
Police recorded 61 collisions with the A4300 as the first road from 2021 to 2025, 6 of them fatal or serious. That is 53.0 per 100 million vehicle miles, higher than the 31.5 for all A-roads in Great Britain. On average there were 3.6 a year for each mile of road.

| Figures | Source | Period | Records | Updated |
|---|---|---|---|---|
| Traffic counts and vehicle mix | Road traffic statistics (AADF by count point) Department for Transport Derived statistics UK Motoring | 2000 to 2025 | 6 count points in 2025 | 15 September 2026 |
| Reported collisions | Road safety open data (STATS19) Department for Transport Derived statistics UK Motoring | 2021 to 2025 | 61 reported collisions | 15 September 2026 |
- Annual average daily flow (AADF) is the average number of vehicles passing a point on a typical day of the year, both directions combined.
- Vehicle miles are AADF multiplied by link length and 365, summed over every count point link on the road.
- Sections join count point links between junctions, using the link lines in DfT’s major road database.
- STATS19 covers personal injury collisions reported to the police. Damage-only collisions are not included, and not every injury collision is reported.
- Serious and slight figures are DfT’s adjusted estimates, which allow for police forces moving to injury-based reporting.
- Counts of one or two collisions below Great Britain level are shown as “fewer than 3”.
