FIELD: transport.
SUBSTANCE: group of inventions relates to technique for manufacturing distinguishing signs for vehicles. The suggested numberplate for vehicle has retroreflecting surface provided with authentication marks which are recognisable from the set direction. Herewith, authentication marks is recognisable from outside of vehicle travelling zone within recognisable zone which has range of horizontal angle of 25° to 75° and range of vertical angle of 5° to 55°. Retroreflecting sheet material is preliminarily provided with authentication marks so that this authentication marks are recognisable from outside of travelling zone of a vehicle equipped with numberplate when retroreflecting sheet material is attached to vehicle numberplate.
EFFECT: group of inventions provides safety of observer and increased efficiency of recognition by surveillance camera.
