The session will also cover vehicle automation, periodical technical inspections, driver distraction and drowsiness warning systems, and door open warning systems.

Report on a workshop organized by the Kingdom of the Netherlands on 25 August 2026 in Brussels to address transparency provisions in UN R43. The workshop discussed current transparency requirements, alternative test procedures for reflection, definitions such as chameleon effect, and amendments to working document ECE/TRANS/WP.29/GRSG/2026/20. Participants agreed transparency provisions are not direction-dependent, confirmed the importance of driver visibility, and noted the absence of measurement procedures or objective criteria for reflection levels. The proposal is to add a footnote to clarify requirements for the driver’s forward field of vision, with future evaluation of whether more objective measurement provisions on reflections are needed.

Letter of support from the International Federation of Pedestrians and the European Cyclists Federation for the proposal for Supplement 14 to the 01 series of amendments to UN R43. The submission supports efforts to clarify regulations and ensure that windows within the driver’s forward field of vision meet minimum light-transmission requirements when viewed from both inside and outside the vehicle, and opposes treatments or tints that prevent people outside the vehicle from seeing the driver.

Proposal to add footnote 1 to para. 6.2. to clarify that safety glazing materials must be sufficiently transparent as a requisite for the driver’s forward field of vision, for the driver to see and to be seen. The amendment aims to clarify possible safety concerns to ensure that the driver can be seen from outside and does not introduce new provisions but clarifies the intent of existing provisions.

Proposal to add footnote 1 to para. 6.2. defining transparency as requisite for the driver’s forward field of vision, for the driver to see and to be seen, and insert new para. 6.3. stating that safety glazing located in a position requisite for driving visibility may not be treated such that it limits or restricts the visibility of the driver from outside, for example by applying a mirror or chameleon effect, with minimum light transmittance provisions as described in Annex 24 applying from both directions.

Session report of WP.29 (World Forum for Harmonization of Vehicle Regulations), its Administrative Committee of the 1958 Agreement (AC.1), Executive Committee of the 1998 Agreement (AC.3), and Administrative Committee of the 1997 Agreement (AC.4) held 23-26 June 2026 in Geneva. AC.1 voted on 92 amendments to existing UN Regulations, one corrigendum to UN Regulation No. 79, and three new UN Regulations (Nos. 184-186) on liquid hydrogen vehicle safety, automated driving systems, and tyre abrasion performance. AC.3 established UN GTR on automated driving systems and adopted corrigendum to UN GTR No. 9 and Amendment 2 to UN GTR No. 13. WP.29 extended mandates of several informal working groups and noted accession of Mongolia and Armenia to the 1958 and 1997 Agreements respectively.

Proposal to amend para. 2.5.2. to change the lower vertical datum point from 5 above the horizontal to 4 above the horizontal, and amend Figure 3 to reflect this adjustment. The modification harmonizes the location of the lower datum point with the angle of obstruction requirement and resolves an inconsistency in UN Regulation No. 43.

Proposal to amend para. 8.2.1.1. to replace “Optional distortion” with “Optical distortion” in the table of tests for windscreens and glass panes. The amendment corrects the title of the optical distortion test listed in the table.

Proposal to insert new paras. 0. and 0.1. to 0.1.4. introducing vehicles of categories X and Y and vehicles with manual modes or automated driving systems, amend para. 1(a) footnote 1, para. 2.13., para. 2.25., paras. 5.4.1. and 5.11.1. footnote 2, insert new para. 2.40. defining “Safety Concept”, amend para. 6.2., para. 7., para. 8.2.1.1., Annex 1A para. 5.1., Annex 3 footnote 18, Annex 21 title, Annex 22 title, and Annex 24 including its scope, definitions, and provisions for safety glazing installation on vehicles. This proposal is based on GRSG-131-23-Rev.1.

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 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 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 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).
