As a result, the current provisions risk impeding the use of beneficial multi-function tell-tales.

44. The expert from OICA introduced GRSG-105-21 adapting the provisions on multi-function displays to technical progress. GRSG noted a study reservation by the expert from France and agreed to resume consideration at its next session on the basis of an official document.

Proposal to refine the text of document GRSG/2013/23 wherein Germany proposed to clarify the provisions on the extended field of vision of heavy goods vehicles across different mirror classes. The text would require assessment of normal and extended fields of vision using a single mirror adjustment and to allow for the loss of up to 10% of the close-proximity field of vision in such configurations.

The informal group Chair informed that the Chair of GRSG recalled the necessity to adopt the final Terms of Reference for the group at the 106th session of GRSG (May 2014).

The Netherlands questioned the scope and raised the concern of mutual recognition in the frame of the 1958 Agreement, should a manufacturer get a Type Approval to this regulation for national application for a vehicle of a category not in the scope of the regulation. It was clarified that the scope in a 1st step, as “if fitted”, will be limited to vehicles of categories M1/N1.
