Question to the Department for Transport:

To ask the Secretary of State for Transport, how many (a) fatal accidents, (b) serious accidents, (c) minor accidents and (d) near misses were recorded on smart motorways for each year from 2015 to date.

National Highways reports annually on smart motorway safety performance. The latest report was published in September 2025 using DfT’s most up to date validated STATS19 casualty dataset and annex A contains a breakdown of casualties by severity from 2015.

The latest analysis continues to show that overall, smart motorways remain our safest roads in terms of deaths or serious injuries, but we have been clear that we will not build any new ones.
