Correction to clarify that the scope of the GTR covers windscreens and panes for cars and trucks and to harmonize the text with ISO 3537/ UN R43. The present text could be read to limit the scope of windscreens and double window panes.

Proposal for an amendment to UN Regulation No. 43 to define a “reduced vision zone I” for vehicles of categories M and N other than M1. The goal is to extend the concept that already exists for M1 vehicles in order to enable the installation of sensors and cameras that improve driving safety.

Proposal to replace the current Figure 2a with a more accurate drawing reflecting the meaning of paragraph 2.4.2.2 of the regulation. The new drawing addresses the lateral limits of any opaque obscuration of the window area.

Proposal to remove ambient light constraints (e.g., 1000 lux threshold) from the draft blind spot information systems text.

Proposal to increase the 0.25 m gap between the vehicle and the bicycle to 0.50 m in order to avoid excessive false positive warnings.

Proposal to add a drawing and text to clarify which requirements apply to which parts of the windscreen wiper.

Proposal to add a missing footnote concerning the exemptions for heaters located outside the passenger compartment using water as a transfer medium and to clarify that it is not necessary to apply Annex 4 for the heat pump because the heat transfer fluid does not contain polluting air.

Proposal to add a missing footnote and to clarify the application of Annex 4 for heat pumps.

Document GRSG/2022/17 addresses provisions for heavy duty vehicles and battery electric cars. This proposal would make editorial changes without altering the meaning of the proposed definitions.

Proposal to introduce options to fulfil marking requirements in cases where more than one Regulation applies (e.g. avoid duplicating the E-Marking).

Proposal to introduce options to fulfil marking requirements in cases where more than one Regulation applies (e.g. avoid duplicating the E-Marking).

This proposal is to add Component and Separate Technical Units (STU) approvals regulatory supplement to the UN Regulation No. 159 for “Uniform provisions concerning the approval of motor vehicles with regard to the Moving Off Information System for the Detection of Pedestrians and Cyclist”
.

The Special Interest Group on Component & Separate Technical Unit (SIG-C&STU) for the Supplement of UN Regulations 151, 158, 159 and 166. Proposal adds Component and Separate Technical Units (STU) approvals requirements.

The Special Interest Group on Component & Separate Technical Units (SIG-C&STU) proposes amendments to UN R159, UN R158, UN R151, and UN R166 to add Component and Separate Technical Unit approvals. For UN R159, the proposal introduces a universal functional block structure separating Detection, Control, and Human Machine Interface functions, with Component or Separate Technical Unit fulfilling Detection and Control as minimum requirements. The regulation is restructured into three parts: vehicles without approved Component or Separate Technical Unit, vehicles with approved Component or Separate Technical Unit, and Component or Separate Technical Unit specifications. UN R158 adds new devices for Rear-View Camera Systems and Detection Systems to Part I, with corresponding installation requirements in Part II. The group requests written comments within four weeks and plans submission to Working Party 29 in June 2026.

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.

The European Association of Automotive Suppliers (CLEPA) proposes changes to the Dutch proposal (GRSG/2011/23) that would enable the replacement of mirrors by camera monitor systems. This document is based on informal document GRSG-101-03.

Proposal from CLEPA to introduce type-approval requirements for Liquefied Petroleum Gas (LPG) fuel selection systems, including with regard to engine control units (ECU), CNG start-stop functionality, and a prohibition against the flow of gaseous fuel into the petrol/diesel fuel tank and vice versa.

Proposal from CLEPA to introduce type-approval provisions for compressed natural gas (CNG) control functionality included in the engine control unit, and for control
functionality which is used in vehicles with start-stop system.

Text prepared by the European Association of Automotive Suppliers (CLEPA) to enable the approval of an OEM engine control unit on a CNG/LNG vehicle during the vehicle type approval process, eliminating the need for a separate type approval of the ECU as is the current requirement.

Text prepared by CLEPA to introduce a prohibition on any flow of a gaseous fuel into a diesel/gasoline reservoir and limiting the flow of diesel/gasoline into a gaseous fuel tank in bi-fuel vehicles.

Text prepared by the European Association of Automotive Suppliers (CLEPA) to introduce into Regulations Nos. 67 and 110 type approval provisions for “valve control at stop-start”. This proposal allows the tank valves to stay open in an active stop-start phase for CNG/LPG with stop-start engines.

Proposal to introduce type-approval provisions for “valve control at stop-start” into the regulation on LPG equipment. The proposal would allow tank valves stay open in a commanded stop-start phase as it is the case for the idling phase of non-stop-start vehicles. These provisions are similar to those for UN R110 on CNG vehicles.

Proposal to introduce type-approval provisions for fuel selection systems into the regulation on compressed natural gas-powered vehicles.

Proposal to introduce type approval provisions for “valve control at stop-start”. The proposal would let the tank valves stay open in a commanded stop-start phase as is the case for the idling phase of vehicles not equipped with start-stop systems. These provisions are similar to those proposed for UN Regulation No. 67
