Motor Vehicles: Lighting
The question
To ask the Secretary of State for Transport, what assessment she has made of the potential implications for her policies of the TRL report prepared for her Department entitled Glare from road vehicle lighting on UK roads, published in October 2025.
Answered by Simon Lightwood
The initial and ground-breaking TRL research demonstrates that glare is a complicated issue with several contributing factors. Any steps we take must avoid unintentionally reducing visibility for drivers or interfering with safety-critical cameras and sensors.
As part of the recently published Road Safety Strategy, we are planning further targeted vehicle-based research to help inform future international lighting regulations and consider what more can be done domestically.
