22. The expert from the Republic of Korea briefed GRB on the status of domestic accidents resulting from reversing vehicles (GRB-66-02). He concluded that M1 vehicles caused the largest number of backup collisions, while N1 and N2 vehicles caused the largest number of fatalities. The expert was of the view that all vehicles should be equipped with at least one safety device for moving backward, like rear view cameras, reversing alarms and parking sensors. The Chair pointed out that GRB should collaborate with the Working Party on General Safety Provisions (GRSG), which was conducting work on rear view cameras. The experts from Germany and OICA were of the view that reversing alarms should be installed on commercial vehicles, while M1 and N1 vehicles should be equipped either with rear view cameras or parking sensors.
