PAS 1881:2020

This PAS specifies requirements for safety cases for automated vehicle trials and development testing in the UK to demonstrate that trialling and testing activities can be undertaken safely and securely.

It covers the development of an operational safety case to demonstrate that the risks to all affected parties throughout automated vehicle trials and testing are reduced as low as reasonably practicable (ALARP). This includes operational risk assessments, safety testing, training, safety monitoring, compliance and permissions granted. It is applicable to all real-world testing environments, including test tracks and public domains and to all levels of driving automation systems. However, a safety case developed for test tracks might not need to include all elements detailed in this PAS.

This PAS does not cover the system safety of the vehicle (e.g. functional safety, safety of the intended functionality (SOTIF) and cybersecurity assessments) but does rely on their outputs. This PAS does not include the safety case requirements for the testing of a connected vehicle that is not also automated.

This PAS is intended for use by trialling organizations, including private developers and original equipment manufacturers (OEMs), developing safety cases for automated vehicle trials and testing. Compliance with this PAS does not guarantee acceptance of the safety case by relevant organizations.

This PAS might be of interest to organizations requiring assurance that a safety case has been developed in line with good practice, for example, highway authorities, road operators, landowners, leaseholders and insurers.
