Proposal to revise the explanation for para. 6.1.2.1. of the ADS UN Regulation. The revision clarifies that where collisions involving the ADS occur during the approval process, including manufacturer’s on-road testing or confirmatory testing, a root cause analysis must be done and an explanation provided. Where the ADS is determined to have played a role in causation, the manufacturer will provide evidence of how related causal factors have been addressed in the final ADS prior to approval. Post-deployment collisions are covered by the ISMR process as implemented within national law.
