A modular outside mirror assembly for a commercial vehicle incorporates an upper body anchorage, with an upper pivot linkage, a lower body anchorage with a lower pivot linkage, a first mirror and a holding arm, onto which the first mirror is fastened. The holding arm is disposed in the upper and lower pivot linkage of the upper and lower body anchorage such that the holding arm is rotatable about an axis relative to the body anchorages. Due to modular construction, a multiplicity of different mirror variants are available. In another aspect a servomotor is attached to the holding arm to pivot the holding arm against or away from a side of the vehicle about a defined turning axis.
