Collision costs

The Department for Transport estimate the values assigned to the cost of road casualties and collisions in Great Britain, for use in cost-benefit analysis of the prevention of road casualties and collisions in road schemes.

The average cost per collision in Scotland and the total cost of all collisions in Scotland in 2025 are presented in 4. These are calculated by applying Scotland’s average numbers of casualties per collision, and the proportions of fatal, serious, and slight casualties recorded in collisions in Scotland to the GB-level estimates.

More information on the way that these figures have been calculated is available in the Supporting Information section.
