Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate her Department has made of the number of road traffic accidents caused by LED headlights affecting drivers' vision.

The Department does not hold data relating to the number of collisions caused by LED highlights specifically.

The Department’s published road casualty statistics include figures for the number of collisions where ‘vision affected by dazzling headlights’ was recorded as a contributory factor by a police officer attending the scene. In 2023, the latest year for which this data is available, there were 216 reported injury collisions with this factor assigned.
