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.
