Document title UN R43: Proposal for a Supplement 13 to the 01 series of amendments
Date 29 Jan 2026

Proposal to align UN R43 with a proposed amendment to UN R125 (ECE/TRANS/WP.29/GRSG/2026/23), which resolves a longstanding inconsistency between the lower datum point definition (§5.1.1.3) and the obstruction requirement (§5.1.3) by harmonizing the lower datum point angle from 5° to 4°.
