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.

Session report of WP.29 (World Forum for Harmonization of Vehicle Regulations), its Administrative Committee of the 1958 Agreement (AC.1), Executive Committee of the 1998 Agreement (AC.3), and Administrative Committee of the 1997 Agreement (AC.4) held 23-26 June 2026 in Geneva. AC.1 voted on 92 amendments to existing UN Regulations, one corrigendum to UN Regulation No. 79, and three new UN Regulations (Nos. 184-186) on liquid hydrogen vehicle safety, automated driving systems, and tyre abrasion performance. AC.3 established UN GTR on automated driving systems and adopted corrigendum to UN GTR No. 9 and Amendment 2 to UN GTR No. 13. WP.29 extended mandates of several informal working groups and noted accession of Mongolia and Armenia to the 1958 and 1997 Agreements respectively.

Proposal to amend para. 6.5.4. to clarify control of cleaning devices when an ADS feature is active, modify manual control requirements for vehicles of categories X and Y, and specify automatic activation requirements when cleaning devices are required under UN Regulation No. 48, and insert a new footnote 4 defining ADS as specified in the Consolidated Resolution on the Construction of Vehicles (R.E.3.), document ECE/TRANS/WP.29/78/Rev.8.

Proposal to amend para. 6.5.4. to permit an automated driving system to control the cleaning device while active and to require the cleaning device to operate through at least one cleaning period when headlamps are switched on and windscreen washers are operated, except for vehicles of categories X and Y, and insert a new footnote 4 defining automated driving system as in ECE/TRANS/WP.29/78/Rev.8, para. 2.
