52. The GRB Chair reported on the results achieved by GRB during its sixty-seventh session (for details, see the report of the session ECE/TRANS/WP.29/GRB/65).

53. In particular, the GRB chair mentioned that GRB had adopted amendment proposals to Regulation No. 51 which would introduce an option of indoor testing, according to standard ISO 362-3, upon understanding that the Type Approval Authority could always mandate an outdoor test for verification. He further pointed out that GRB had addressed the pending issue of transitional provisions for the earlier amendment proposals to Regulation No. 51 which had been submitted to the March 2018 session of WP.29 as ECE/TRANS/WP.29/2018/7. GRB had agreed that these proposals should be introduced as a Supplement with an 18-month transitional period and requested the secretariat to issue an addendum to ECE/TRANS/WP.29/2018/7.

54. The GRB chair also reported that GRB was preparing a new draft Regulation on reversing alarm and had established a task force for that purpose. The task force would soon distribute a questionnaire to contracting parties to collect information on national practices with respect to reversing alarms. Based on responses, the task force would draft a new Regulation.

45. The World Forum recalled the report of the Chair of GRB on its sixty-fifth session (ECE/TRANS/WP.29/GRB/65) and approved the report.
