UN R145 has been prepared purely as documentation tool. The authentic and legally binding text is WP.29/2017/133. This document incorporates the following change:

Proposal to consolidate provisions concerning ISOFIX anchorages systems, ISOFIX top tether anchorages and i-Size seating positions removed from Regulation No. 14 in a new regulation.
