The present invention relates to a towed trailer, which is configured to be self-operated even when a towing vehicle is not available for use. To this end, the towed trailer according to the present invention comprises: a vehicle body forming a loading space; and a wheel which is individually installed at the left and right sides of the vehicle body. The present invention further comprises: a pair of moving assemblies which come in contact with the wheel when required to deliver rotational force by means of the friction with the wheel; and a hydraulic driving device which provides driving force to operate the moving assemblies. The moving assemblies comprise: a roller which performs a rotational movement; a roller driving motor which causes the rotational movement of the roller; and a hydraulic cylinder which moves the roller in forward and backward directions in a linear direction to vary the distance between the roller and the wheel.
