Regulations for On-Road Testing of Connected and Automated Vehicles: Assessing the Potential for Global Safety Harmonization

Although there is great media attention to connected and automated vehicles (CAVs) and strong public interest in the technology, it is still under development. Their deployment to the broader public will require new regulations and road traffic rules that are also under development, and there is not yet a globally harmonized approach. This paper reviews the main safety and liability issues for CAVs with a focus on the rules developed for on-road testing to date in Australia, the United States, and Germany. It also reviews government policies from Victoria, Australia, and California, the United States, and it provides an appendix on European Union (E.U.) regulations. After a review of similarities and differences regarding safety and liability provisions, the study suggests how the current provisions can be brought together toward a globally harmonized approach to safety issues that builds on best practices in the three countries.
