18. The expert from Japan introduced ECE/TRANS/WP.29/GRSG/2024/38, by way of GRSG-128-17, to improve the effectiveness of Lateral Protection Devices (LPDs) in preventing left- or right-turn collisions. He added that the proposal aimed to: (a) eliminate the exemption for semi-trailer tractors, (b) reduce the lower edge ground clearance of LPDs, © clarify the upper edge structure of LPDs and (d) add exemptions ensuring requirements for the Blind Spot Information System for Heavy Trucks (BSIS). The expert from the United Kingdom stated that LPDs were relevant for the protection of cyclists. However, he asked for statistic to justify the proposal. The expert from Canada explained that research demonstrated that LPDs were effective when bicycles and trucks were driven in the same direction side by side. The experts from CLCCR and OICA also requested statistical evidence. The expert from France agreed, in principle, with the proposal from Japan on an LPD ground clearance of 450 mm and added that LPDs were also effective for motorcyclists. At the same time the expert from the United Kingdom introduced GRSG-128-11 to allow extendible trailers to conform to all lateral protection requirements for trailers regardless of length. The experts from Finland, France and the Kingdom of Netherlands expressed support for the proposal. The expert from CLCCR argued that the proposal would be a new series of amendments with transitional provisions. Finally, GRSG agreed to resume discussion on ECE/TRANS/WP.29/GRSG/2024/38, based on further statistical evidence provided by the expert from Japan at the April 2025 session of GRSG. At the same time the secretariat was requested to distribute GRSG-128-11 with an official symbol at the next session.
