UN R159 concerns systems that detect pedestrians and cyclists in the near-front blind spot of M2, M3, N2 and N3 vehicles and inform the driver. A warning of a possible collision may also be provided depending on the manufacturer’s strategy. Its scope includes adapting criteria to traffic direction and the possibility of an approval-authority exception for certain incompatible uses.

Which subjects are addressed?
- Near-front blind spot
