1. Traffic estimates are based on an "urban/rural" split which differs slightly from the "built-up/non built-up" classification used for the number of accidents. Therefore, these rates are approximations: the "non-built up" rate is the number of accidents on "non-built up" roads divided by the estimated volume of traffic on "rural" roads, for example. The figures given in this table take account of any revisions to the traffic estimates for previous years.

2. Due to changes in the the way casualty severities are recorded, figures for serious casualties in 2019 and 2020 are not comparable with previous years.
