An arrangement for communication between motor vehicles is specified. The arrangement comprises a reflector apparatus that is secured at a fixed location in the outer region of a curve or of a curve-like road. The reflector apparatus is in an orientation such that said reflector apparatus deflects electromagnetic radiation in the frequency band between 2.5 GHz and 7.5 GHz that is emitted by a first motor vehicle, situated in the region of a curve entrance, toward a second motor vehicle, situated in the region of a curve exit. Furthermore, a corresponding reflector apparatus for the arrangement is specified.
