Local trends in killed & seriously injured
Severity-adjusted KSI by region and upper-tier local authority, comparing the latest year (2025) with
pre-pandemic 2019 and with the 2022–2024 strategy baseline. Green = fewer KSI (improving); red = more (worsening).

About the data. Source: DfT, Reported road casualties in Great Britain: provisional estimates 2025, table RAS91. KSI figures are severity-adjusted to account for differing injury-reporting systems across police forces. 2025 figures are provisional and subject to revision.
Reading the maps. Colour shows the percentage change in adjusted KSI. The 2022–24 baseline is the three-year mean used in the national road safety strategy. Small-count caution: at local-authority level many areas record few KSI, so single-year percentage changes are volatile and dominated by random variation — use the low-count flag and treat large swings in small authorities sceptically. Regional and local figures exclude collisions with unknown location and so do not sum exactly to the GB total.
