49. The expert from Australia, as Chair of the IWG regarding the safety of Children Left in Vehicles (CLIV), gave a presentation on its work (informal document GRSP-76-37), including a status update and recommendations for the next steps. He proposed that the IWG develop first a new UN GTR and then transpose it into a new UN Regulation. He informed GRSP that the IWG would prioritize developing the provisions for buses, and then would develop provisions for passenger cars. Some experts expressed concern that the work on passenger cars might be delayed by this strategy, but the experts from Canda and Australia assured that the work on passenger cars would continue in parallel to the work on buses.

51. The expert from OICA highlighted the importance of a technologically neutral solution, as already stated in the IWG report, and of worldwide harmonization. He also requested that the Working Party on General Safety Provisions (GRSG) was briefed on the progress of the work.

52. The expert from CI suggested that it might be beneficial to host one of the upcoming meetings of the IWG in Europe.
