Proposal to exempt ADS vehicles of subcategories X and Y from requirements related to the presence of a human driver and manual driving controls. The proposal permits X and Y vehicles to use alternative materials for windscreens given their 6 kph speed restriction. The proposal further permits translucence levels below 70% for ADS vehicles while an ADS feature is active (i.e., performing the DDT).

Proposal to clarify that transparency requirements under UN R43 apply in both directions (exterior to interior and interior to exterior), addressing the growing use of privacy foils on windscreens and front side windows post-registration, which raises safety concerns regarding driver eye-contact, law enforcement visibility, and driving behaviour enforcement, consistent with the position expressed by GRSG at its 130th session.

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°.
