GTB comments to draft list of recommendations for GRE based on TFGP-08-06 assess glare prevention measures across effectiveness categories. Recommendations include introducing adaptive cut-off lines, motorway ADB, dynamic adaptive low beam, and improving ADB requirements for latency and vehicle detection. GTB ranks headlamp cleaning devices and maximum intensity output as low effectiveness. PTI-related items include clarifying practical aspects, defining uniform requirements for floor evenness and headlamp aiming devices, and improving coordination between type approval and inspection requirements. General considerations address driver awareness and manual overrides. Knowledge gaps concern aiming differences and alignment degradation.
The Task Force on Tyre Abrasion completed work on the UN Regulation on tyre abrasion for C1 tyres and is launching C2 work. UN R186 on tyre abrasion for C1 tyres was adopted at WP.29’s 199th session in June 2026, with a two-stage implementation approach beginning 30 June 2028. C2 test method development is ongoing with an Informal Document to be submitted to GRBP in February 2027 instead of September 2026. C3 tyres will undergo a brainstorming session in October 2026 before commencing testing.
A two-day brainstorming session will be held in Brussels during October 8-9, 2026. The session aims to address the lack of a concrete test method solution for C3 tyre abrasion by reflecting on innovative test method ideas not bound to existing C1 and C2 approaches, brainstorming phased introduction of tyre abrasion requirements across C3 tyre segments, and optimising resources to reduce testing burden. Day 1 will address C3 market complexities and tyre segmentation across duty cycles; Day 2 will cover methodological ideation, funding and resource allocation, and review of the C2 test campaign before the February 2027 working document.
GRE will be informed about considerations of the Global Forum for Road Traffic Safety (WP.1) at its recent session and about liaison between GRE and WP.1 on common issues.
