Change of the speed limit for Automated Driving Systems

A new milestone in mobility has been achieved with the adoption of the proposal to increase the maximum driving speed with the Automated Driving Systems from the current limit of 60 km/h to 130 km/h on motorways for passenger cars (Category M1) and light commercial vehicles (Category N1).  

Amendment to UN Regulation No 157 (ECE/TRANS/WP.29/2022/59/Rev.1), which was adopted by the UNECE World Forum for Harmonization of Vehicle Regulations (WP.29), will enter into force in January 2023 in the countries that agree to implement this change. The Amendment also allows the vehicle to perform an automated lane change procedure and allows the use of ADS on roads where pedestrian and cyclist traffic is prohibited and which are intended to have physical separation between the traffic of vehicles traveling in opposite directions [].

The aforementioned UN Regulation No 157 (ECE/TRANS/WP.29/2020/81), adopted in June 2020, provides uniform rules for the approval of vehicles for the ALKS (Automated Lane Keeping Systems). It is the first binding international regulation for vehicle automation according to SAE level 3 (Society of Automobile Engineers). Activation  the ALKS shifts the primary control of the vehicle to the system, and allows it to control longitudinal and transverse a movement of the vehicle for long periods without any additional commands from the driver [].

The amendment to UN Regulation No 157 was prepared by the Working Party on Automated/Autonomous and Connected Vehicles (GRVA) based on the experience gained from different countries following the adoption of this Regulation.
