Question to the Department for Transport:

To ask the Secretary of State for Transport, what steps she is taking to conduct research into increased headlight glare from different makes and models of vehicles.

The Department commissioned ground-breaking independent research into headlamp glare in 2024, which was published in November 2025. This provided an important first step and a second phase of research is being developed to identify the vehicle design factors that may be responsible. Officials are currently engaging with relevant stakeholders to inform the programme of work, and we expect to procure and commission this next phase in the spring.
