When collisions happen
The busiest hour was 5pm to 6pm, and 35% of collisions happened between 3pm and 7pm (higher than the 32% across Great Britain). Friday had the most collisions, and 22% happened at weekends.
Trend over time
Reported collisions went from 366 in 2021 to 414 in 2025, a rise of 13%. Counts are affected by traffic levels, population and changes in how police record injuries, so South Gloucestershire 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.
