Question to the Department for Transport:

To ask His Majesty's Government what assessment they have made of the risks relating to the glare of LED headlamps; whether they have been identified as a contributing factor to road accidents at night; and what steps they plan to take, if any, to mitigate these risks.

National collision statistics, which can record headlamp dazzle as a contributory factor, do not show any discernible trend to suggest that advances in lighting technology are contributing negatively to road vehicle collisions.

However, noting increased public concern, Government has commissioned independent research to better understand the root causes of headlamp glare and develop potential countermeasures. The work is underway and is due to deliver in summer 2025.
