TOPICS

SUMMARY

First amendment to UN-R157 expanded ALKS scope from 60 km/h to 130 km/h and added provisions for lane changes. Original R157 (2021) was the first international regulation approving a Level 3 feature for mass production. Germany's Mercedes DRIVE PILOT was first approved under R157.

IMPACT / ANALYSIS

Defines the baseline for any Level 3 highway autonomy globally. Chinese OEMs seeking European market entry for L3 features (e.g., Geely/NIO/HIMA) must comply.
