Summary
This report summarizes information on the laws and regulations for Level 3 and above autonomous driving in major countries and regions as of January 2023. Regulations for driver assistance systems below Level 2 are not addressed.
As of January 2023, UN regulations (UN-R157-01 series), in Japan and the EU, allow for the approval of Level 3 autonomous driving devices with a maximum speed limit of 130 km/h on highways and the ability to change vehicle lanes.
Future work on developing regulations will focus on regulations for Level 4 and 5 unmanned (driverless) vehicles.
The U.S. and China have not adopted UN-R157, and each is working on its own legislation.
Autonomous driving is classified into three levels: Level 3 (conditional driving automation), Level 4 (high driving automation; full automation under specific conditions), and Level 5 (full driving automation).
The definition of autonomous driving levels is based on the American Society of Automotive Engineers (SAE) definitions of Level 0 to Level 5, which is used as the basis for the classification. Note that the expression "Level 2.5" can also be found for hands-off functions that are within the scope of Level 2 (partial driving automation) but closer to Level 3 (conditional driving automation).
