Proposal from Italy with support from IMMA to adapt GTR No. 3 to technical and standardization progress, introducing provisions for the activation of the stop lamp under regenerative and/or automatically commanded braking, and updating the references to ASTM standards to enable the use of the new ASTM standard reference test tyre F2493 for the measurement of the Peak Braking Coefficient (PBC).
Proposal to further align the stop lamp signal provisions in UN R78 with UN R13-H to ensure consistent stop lamp behaviour across different vehicle categories and therefore avoid confusion to road users driving behind a braking vehicle regardless of its category.
Proposal to amend the extended mobility tyre (EMT) symbol following the detection of dimensional inconsistencies within the International Organization for Standardization Working Group (ISO) TC31/SC3/WG19, where the dimension “0,33h” was judged wrong and constituting an unnecessary over constraint and to amend the inflation value to be used for the tyre conditioning when assessing the “flat tyre running mode” of “run flat tyres” and of “extended mobility tyres”.
Proposal to clarify the scope and application of the regulation.
Proposal to improve the Appendix 2 Annex 3 for assessing robustness against false reaction, to introduce new provisions for automatic deactivation of AEBS, and to improve the text in other instances.
Proposal to introduce provisions under a car-to-bicycle test scenario.
Proposal for amendments that allows for tyre marking methods other than moulding.
Proposal to create a new UN Regulation on uniform provisions concerning the approval of a vehicle alarm system and approval of a vehicle with regard to its vehicle alarm system, pursuant to splitting the UN R116 into three separate regulations.
Proposal to create a new UN Regulation on uniform technical prescriptions concerning approval of immobilizers and approval of a vehicle with regard to its immobilizer, pursuant to splitting UN R116 into three separate regulations.
