We examine the dynamics of an elastic string interacting with quenched disorder driven parallel to the string. For a moving parallel-driven string we show that there is a finite transverse critical depinning force which decreases for increasing parallel drive. The depinning transition is hysteretic and occurs by the formation of running kinks.
