39. The expert from Germany introduced ECE/TRANS/WP.29/GRSP/2019/18 and referred to agenda item 3(b) (see paragraph 8 above): a clarification was proposed on the issue of pedestrian protection and variable suspensions. He added that since the vehicle height influenced the head-form test impact zone and the legform test, all possible vehicle heights up to a driving speed of 11.1 m/s (40 km/h) should be considered as relevant for impact with a pedestrian. GRSP acknowledged that the proposal affected both UN GTR No. 9 and UN Regulation No. 127 and agreed to defer discussion to its May 2020 session. At the same time, the expert from Germany was requested to devise transitional provisions to implement the proposed requirements.
