College welcomes government-commissioned TRL report into headlight glare
The TRL study shows a link between the brighter modern vehicle headlights and glare.
“We welcome this new TRL study. It is independent evidence that confirms what our own research has been showing for some time, that there is a link between brighter headlights and glare. Drivers are increasingly struggling with glare from modern headlights, and many are now choosing to avoid driving in the evening and night altogether so it resulting in people losing their independence. The study also highlights that glare worsens when vehicles meet on hills or bends, and that the current UK lighting regulations, which are based on laboratory measurements of luminous intensity rather than the luminance experienced by drivers, is no longer sufficient with modern headlight technology.
“While the study identifies evidence gaps, including limited data on specific vehicle models, weather conditions and older drivers, it sends a clear signal that change is urgently needed. The challenge now is to turn this evidence into action, to update lighting standards and help ensure that everyone can drive safely and confidently after dark. We look to the DfT to take immediate, actionable steps to support drivers and commission more detailed research, specifically into how headlight regulations need to change, to reduce the impact of disability glare when driving at night.
“While the government reviews these findings, we urge drivers to remember to wear their prescribed glasses or contact lens for driving at all times. Anyone experiencing issues with their vision while driving should contact their local optometrist for advice as soon as possible to ensure drivers can see as clearly as possible and any eye health issues are detected and managed early.”
