We have studied the charge density wave (CDW) transport in the presence of a single-particle current flowing transversely to the sliding direction of the CDW. The depinning treshold field was found to decrease exponentially with the transverse current, allowing the CDWs to slide even at very low bias fields. The CDW transport is ohmic in this novel, nonequilibrium regime. The results from thin NbSe3 crystals are in excellent agreement with recent theoretical predictions.
