The busiest hour was 6pm to 7pm, and 30% of collisions happened between 3pm and 7pm (fewer than the 32% across Great Britain). Wednesday had the most collisions, and 25% happened at weekends.
Trend over time
Reported collisions went from 1,144 in 2021 to 1,147 in 2025, a very small change. Counts are affected by traffic levels, population and changes in how police record injuries, so Westminster should not be ranked against other areas on these numbers alone.

About these figures
Only collisions involving injury that were reported to the police are counted. The figures are not adjusted for traffic volume or population, so they should not be used to rank areas against each other. Serious and slight splits use the Department for Transport's severity adjustment. Full explanation.
