UN Regulation No. 157
Automated Lane-Keeping Systems (ALKS)
Series of Amendments, Supplements, and Corrigenda

This page lists changes to UN R157 by series of amendments, supplements, and corrigenda. A new series occurs when there is a material change in requirements such that an approval granted prior to the change is not equivalent to an approval given after the change. A supplement generally improves the clarity of the regulation; however, a supplement may also involve changes to the scope (range of products) covered by the regulation. A corrigenda is a correction to the text.
