The Task Force on Glare Prevention presents recommendations to address glare from headlamps. Regulatory considerations include introducing adaptive cut-off lines, mandatory dynamic auto-levelling, Motorway Adaptive Driving Beam mode requirements, beam dimming for wet roads or urban areas, lowered maximum headlamp installation heights, improved automatic high-beam switching and ADB requirements, and maximum low-beam intensity limits. Additional recommendations address headlamp cleaning devices under UN R45, driver reminders, and user manual instructions. PTI-related considerations cover vehicle weight influence, floor evenness, cut-off line definitions, and coordination between type approval and inspection requirements. General considerations include driver instructions for ADB manual override and investigation of aiming differences. Actions beyond GRE mandate address illegal products, driver awareness, and infrastructure improvements.
Adaptive Driving Beam: A main beam of an AFS that adapts its beam pattern to the presence of oncoming and preceding vehicles in order to improve the long-range visibility for the driver without causing discomfort, distraction or glare to other road users.
