GIDAS data analysis examined abdominal injuries in car crashes from 2005–2025. Case selection included passenger cars registered 2005–2025, occupants over 11 years old, belted, with at least AIS 1 in AIS15REG5. The study analyzed 234 cars with 248 occupants sustaining abdominal injuries. Frontal impacts accounted for 71%, rear impacts 12%, left side impacts 10%, and right side impacts 8% of cases. Analysis examined injury distribution across AIS levels, gender, age, height, weight, delta V, seating position, and specific abdominal injuries.

Based on GRVA-25-08, the document addresses blind spot accidents involving right-turning trucks and bicycles. It distinguishes between warning systems requiring driver reaction time and automatic brake intervention systems. The document notes that information systems with low intensity have low annoyance and low risk of deactivation, while high-intensity warnings risk driver annoyance and deactivation. It describes a specific scenario at approximately 15 km/h where a truck brakes after a turn has started with a bicycle detected at high confidence. The document indicates that next steps in safety regarding blind spot accidents should involve automatic brake intervention and suggests future discussion of UN R151 in GRVA.

Y-category vehicles are equipped with an Automated Driving System and not designed to carry occupants. They may develop aggressive front structures that could harm passenger cars in accidents. The proposal introduces the Occupant Load Criterium (OLC), derived from velocity-time graphs in crash tests, as a compatibility assessment criterion. OLC multiplied by vehicle mass indicates impact aggressivity. Data from ODB tests show OLC values range from approximately 22 to 35 g across various vehicles. The proposal suggests using a maximum OLC × mass value to prevent excessively aggressive vehicle front structures while keeping current passenger car designs unaffected.

This document addresses terminology inconsistencies in UN R11 regarding emergency door opening. It proposes consistent use of entry or exit and occupant(s) versus passenger(s) in amendments without editorial changes to existing parts. Step-by-step checks of all parts of UN R11 are proposed for locking device terminology and latch release control terminology, with definitions for latch release control and door handle already available. For power supply terminology, a definition is needed, while power loss terminology should be retained.
