29. The expert from India introduced GRSG-130-01-Rev.1, proposing the introduction of a new L3-5 category into the Consolidated Resolution on the Construction of Vehicles (R.E.3). The new category of motor vehicle incorporated the 2-wheeler and the 3-wheeler into a single module. He added that this category had recently been implemented in the regulatory framework for India, offering a versatile and innovative approach to sustainable and affordable mobility. The expert from OICA endorsed the idea of promoting mobility in low- and middle-income countries. The expert from IMMA welcomed the proposal from India and expressed interest in continuing the discussion as the proposal evolves. The expert from China announced that a similar initiative in his country would be presented at the April 2026 session of GRSG. GRSG agreed to keep the proposal in this agenda item for further consideration at the next session of GRSG.

30. GRSG reviewed a note from the representative of the European Agricultural Machinery (CEMA) addressed to the Chair of the Inland Transport Committee. In this note, he expressed concerns about ongoing proposals, such as the inclusion of tractors (category T) into the R.E.3 subcategories for autonomous vehicles and in the scope of Autonomous Driving Systems (ADS) UN Regulations (which target on-road operation), are being pursued without substantive dialogue on their relevance or necessity for our industry. The expert from the Kingdom of the Netherlands, on behalf of the Task Force on Automated Vehicle Categorisation (TF AVC) answered to these concerns in a detailed way:

1. R.E.3 has been amended, with new categories X and Y added for the introduction of ADS. Theoretically, it is possible to link categories T and X, which would result in, for example, category T5X, but this is a theoretical possibility to make R.E.3 future-proof. There is no reason to specifically exclude category T (and category L, for that matter) from this theoretical possibility.
2. There is currently no priority from the industry or Contracting Parties (CPs) to draw up or develop any requirements for equipping category T vehicles with an ADS that can be used on public roads. Until such requirements are in place, a category T vehicle may not be equipped with an ADS that can be used on public roads.
3. There was a misunderstanding on ADS UN Regulation development including category T in its scope. At present, categories M, N, L6 and L7 are covered, and where it will remain for the time being.
4. When amending the UN Regulations under the responsibility of, for example, GRSG, we do not consider the UN Regulations related to categories T, R or S until there is a need to do so. For GRSG, this applies, for example, to UN Regulations Nos. 71 and 147.

31. He concluded that the initiative to develop requirements for vehicles equipped with an ADS did not come from CPs but from the industry. As long as CEMA did not need to allow a category T vehicle with an ADS for use on the road, TF AVRS would not deal with this within the development of these UN Regulation. Therefore, an ADS on a category T vehicle is not allowed to operate on public roads until suitable requirements have been drawn up and a party such as CEMA will be closely involved if this ever happens.
