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 (42.9% of today’s road for 2019). In 2025, 5 of the 12 count points were counted; DfT estimated the rest from earlier counts and local trends.
M55 collisions
Police recorded 103 collisions with the M55 as the first road from 2021 to 2025, fewer than 3 of them fatal or serious. That is 7.4 per 100 million vehicle miles, higher than the 4.9 for all motorways in Great Britain. On average there were 1.5 a year for each mile of road.

- 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”.
