In a groundbreaking study, the Transport Research Laboratory (TRL) is examining the impact of headlight glare on road users. Equipped with specialized instruments, the study will assess light levels, weather conditions, and ambient lighting to better understand the factors contributing to glare. The investigation follows numerous complaints from drivers and cyclists about discomfort caused by bright headlights. Notably, experts highlight the potential dangers, as disorientation from bright lights can lead to serious accidents. TRL plans to publish its findings and recommendations for the Department of Transport in spring 2024.
