Proposal to amend and supersede document ECE/TRANS/GRSG/2026/2 to UN R43. Supplement 13 to the 01 series of amendments introduces provisions for vehicles of category X and Y, and vehicles with manual mode operating above 6 km/h equipped with Automated Driving System Feature of Type 2. The amendment extends application to vehicles without driver and manual driving controls. Different manual modes are considered: remote-control operation, seated driver operation for category X, and onboard operation other than seated for category X. Requirements for windscreens, safety glazing, light transmittance, and installation provisions are modified accordingly for these vehicle categories.

Proposal to correct the wording in UN R43 (Safety Glazing). The expert from the European Association of Automotive Suppliers proposes amending paragraph 8.2.1.1. to modify a table listing tests for windscreens and glass panes of various types, including toughened glass, ordinary laminated glass, treated laminated glass, and glass-plastics. The amendment corrects the title of the optical distortion test listed in the table.

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°.

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).
