We examine the dynamics of driven classical Wigner solids interacting withquenched disorder from charged impurities. For strong disorder, the initialmotion is plastic -- in the form of crossing winding channels. For increasingdrive, the disordered Wigner glass can reorder to a moving Wigner smectic --with the electrons moving in non-crossing 1D channels. These different dynamicphases can be related to the conduction noise and I(V) curves. For strongdisorder, we show criticality in the voltage onset just above depinning. Wealso obtain the dynamic phase diagram for driven Wigner solids and prove thatthere is a finite threshold for transverse sliding, recently foundexperimentally.
