50. The expert from EC presented ECE/TRANS/WP.29/GRSG/2019/19 proposing to update the provisions on frontal underrun protection to be approved as integrated part of the vehicle, and to allow more a rounded shape of cabs for better aerodynamic performance. The expert from OICA introduced GRSG-117-36 highlighting the need for keeping exceptions for vehicles of Category G and proposed to cover the issue of the scope in a separate proposal. 51. Following detailed technical discussions and adjustment of language used (GRSG-117-55), GRSG agreed to submit it to WP.29 and AC.1 as proposal for 01 series of amendments to UN Regulation No. 93 for consideration at their June 2020 sessions and thus providing for reconsideration by GRSG at its 118th session. 50.
