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.

Proposal to establish provisions for periodical technical inspections of automated/autonomous vehicles. The document, based on ECE/TRANS/WP.29/2019/34/Rev.2, addresses vehicle safety of in-use vehicles through maintenance and inspection measures. Inspection requirements should verify proper condition and functionality of vehicles and Automated Driving System according to UN Regulations. Provisions should include test procedures for safety-relevant functions, status and fault information, harmonized access protocols, functional test procedures with threshold limits, and result data specifications. Test methods shall be carried out by qualified persons without dismantling using standard equipment.
