The meeting will address coordination of work, pollution emission control in PTI including PN measurement, NOx measurement, and Euro 7, Advanced Driver Assistance Systems and Automated Driving Systems including PTI using diagnostic devices and inspections of automated vehicles, PTI provisions for brakes, lighting devices coordination and inspection, and 1997 Agreement updates.

The IWG on PTI Provisions for PTI works on whole-life compliance, testing ADAS/ADS at Periodic Technical Inspection, ePTI provisions, driverless vehicle inspection, and anti-tampering measures across 2025–2027. Provisions for PTI exist in at least 20 UN Regulations as of 8 April 2026, though PTI experts deem some insufficient and additional provisions may be needed. The proposed update procedure requires the IWG to generate a current provisions list, present needs to WP.29, develop proposals for the first 2–3 UN Regulations, defend each proposal in relevant GRs, and transmit outcomes to WP.29 for decision.

CITA presented PTI-42-02 to link the PTI informal group’s work to the approval of the EU Roadworthiness Package. FSD proposed work to introduce PTI provisions into UN Regulations under the 1958 Agreement. Japan, Russia, and FSD provided brief updates on the use of diagnostic devices to access to in-vehicle data. CITA updated the group on its views concerning PTI for ADS vehicles. CITA explained GRVA/2025/43, GRVA/2025/44, GRVA/2025/34, and GRVA-23-18/Rev.1 on Electromechanical Braking and Parking Lock Devices which will be considered by WP.29 in March.
