Japan is considering a system to screen and approve providers of fully automated driving services within limited areas, under the supervision of prefectural public safety commissions, the National Police Agency said Thursday.

The agency says it aims to submit an amendment to the road traffic law to parliament next spring, as the government intends to start "Level 4" automated mobility services in designated areas of the country, such as along abandoned railroads, in the fiscal year that runs through March 2023.

Operating under Level 4 automation, a vehicle always performs the functions of acceleration, steering and braking, including in emergencies, according to the Economy, Trade and Industry Ministry.
