FIA proposes that vehicles in automated mode in mixed traffic should be marked with one light visible from all sides. Marker lights should have uniform colour and shape clearly distinguished from other signal lights, be positioned at sufficient distance from signal lights and headlamps to avoid impairing visibility, and be designed to not glare other road users.

FIA expresses concerns about logos on side marker lamps, stating that distraction in road traffic is a main reason for accidents and injuries. From a traffic safety perspective, there is no need for logo presentation on light sources or lamps, as their primary function should remain strictly focused on visibility and safety. FIA recommends that if Contracting Parties see a need for illuminated logos on side marker lamps, these should appear in a size not visible on moving traffic, only from close distance, with a maximum total size of 4 cm.

Presentation on truck underrun accident prevention examining active safety system performance and rear underrun protection crashworthiness. ADAS testing of seven modern vehicles (2025–2026) at speeds 56–130 km/h toward stationary truck targets in four scenarios found systems currently unable to reliably prevent collisions on motorways. Conspicuity testing of trailers identified reduced performance with offset approaches and darkness. Crash testing of European UN R58.03 rear underrun protection against US IIHS Toughguard at 56 km/h demonstrated latest European RUP incapable of preventing underrun, with recommendation that regulation mandate tougher RUP standards.

The document addresses on-board authentication and authorization in connected vehicles, a complex area involving multiple stakeholders, use cases, implementations, and standards. The core challenge is distinguishing legitimate remote interactions from misuse, manipulation, and integrity loss. Discussions have occurred since 2023 across GRVA, CS/OTA, and WP.29. FIA seeks feedback on establishing the topic and will develop a scoping document and demonstrator based on select use cases including accident investigation, law enforcement, emergency response, energy monitoring, battery tracking, parts replacement, and ITS-related safety. Contracting parties are invited to submit comments and use cases by 15 June 2026 for consideration at the November WP.29 session.

Progress report on Authentication and Authorisation (OBAC) work. Since the 25th GRVA session, a brief update was provided to the 199th WP.29 session in June, input was gathered from contracting parties regarding scope, needs and directions, use cases were set for initial focus including DSSAD, OBFCM, Digital Key and ePTI, and rationale was refined. A Support Paper is now being drafted for introduction through WP.29.

FIA convened a group of interested parties to develop a scoping document on on-board authentication and authorization. Participants expressed support and called for proof of concept built around use cases. Harmonizing access methods was suggested to reduce cybersecurity fragmentation. Key question raised: which authority authenticates and grants access to legitimate parties? Next steps include establishing concrete use cases and providing a recommendation for WP.29 in November. Planned activities prior to the 200th Session of WP.29 in November include finalizing meetings with GR leaderships and other stakeholders, assembling a Group of Core CPs (GCC) to set scope based on use cases, conducting internal work, aligning with the GCC, and updating WP.29 with objective to obtain a mandate for formal work on the topic.
