Question to the Department for Transport:

To ask the Secretary of State for Transport, whether his Department has made an estimate of how many road traffic accidents are caused by (a) potholes and (b) poor road conditions each year.

The Department publishes road casualty statistics based on personal injury road collisions reported to the police via the STATS19 reporting system.

STATS19 does not identify the cause of collisions, but reporting police officers can identify up to 6 factors which in their opinion may have contributed to the collision.

In 2022 (the most recent year for which data is available) there were 477 personal injury road collisions in which the ‘poor or defective road surface’ contributory factor was assigned.
