47. The expert from GTB presented driver assistance projections as a new feature of the adaptive driving beam with the aim to increase driver’s comfort and road safety (GRE-82-40). The presentation was accompanied by a live demonstration of three vehicles equipped with the new feature. To allow for the driver assistance projections, the expert proposed amendments to UN Regulations Nos. 48 and [149] (GRE-82-04, GRE-82-40).

48. GRE welcomed both GTB presentation and demonstration. Several experts were of the view that the new system could bring safety benefits provided that:

• Road projections symbols are standardized (e.g. according to UN Regulation No. 121).
• Road projections symbols do not distract other drivers.

49. The expert from Japan informed GRE about his intention to commission a study on the reaction time when symbols are used. The expert of Finland recalled an ongoing discussion on the field view assistant within the Working Party on General Safety Provisions (GRSG) and called for cooperation between GRE and GRSG. GRE invited GTB to consider the comments made and decided to revert to the issue at the next session.

50. The expert from Poland proposed to add a reference to DRL in paragraph 4.4.1. of UN Regulations No. [148] (GRE-82-10-Rev.1). The expert from IWG SLR stated that this proposal would be included into the consolidated package of amendments to the above UN Regulation.

51. The expert from India proposed deleting the prohibition to use lighting and light-signalling devices other than those prescribed in UN Regulations Nos. 53 and 74 (GRE-82-15). Several experts disagreed with this proposal and therefore GRE did not support it.

52. The secretariat drew the attention of GRE to the fact that the new definition of “External status indicator”, which had been introduced by Supplement 11 to the 06 series of amendments to UN Regulation No. 48 (paragraphs 2.7. and 2.37 of ECE/TRANS/WP.29/2018/84), was left out of Supplement 12 (ECE/TRANS/WP.29/2018/99/Rev.2). GRE requested the secretariat to submit a rectifying document to the March 2020 sessions of WP.29 and AC.1.
