BS BSI Flex 1888 v1.0:2024-10

This BSI Flex gives guidance for selecting the minimal risk manoeuvres (MRMs) and minimal risk conditions (MRCs) that highly automated vehicles (AVs) require when the automated driving system (ADS) is degraded or fails, or when other events demand.

It provides a framework for consideration of the risks involved in AV manoeuvres and the risks related to the conditions at the location where the vehicle stops, with the objective of minimizing the overall risk and achieving the safest possible outcome. The nature of the event triggering the MRM is key to selecting the combined MRM and MRC with the lowest overall risk.
