UN R79 mandates verification that appropriate warning signals are provided to the driver based on the timing of a system intervention (e.g., in the case of a Risk Mitigation Function). This proposal aims to clarify the moment of initiation of the signals to facilitate the verification of driver warnings, hazard lights, and other indicators in relation to this objectively determined initiation point. The proposal requires manufacturers to define a clear and accessible method for objectively determining the moment of initiation.
