We can easily find this data for the UK as a whole.
- In 2022, trucks (which we take to be Heavy Goods Vehicles (HGVs[HGVs]) accounted for 17.4 billion of the 323.8 billion vehicle miles traveled, which is 5.4% (source).
- Between 2016 and 2021, collisions with single HGVs accounted for 89 of 654 cyclist fatalities, which is 13.6% (source).
- Between 2016 and 2021, collisions with single HGVs accounted for 277 of 2551 pedestrian fatalities, which is 10.9% (source).
This is less extreme than the quoted numbers for London, but still shows a similar trend where HGVs are relatively over represented in fatal collisions with bikes and pedestrians.This gives any idea of how "universal" this pattern is.
