We study the melting of a moving vortex lattice through numerical simulations with the current-driven 3D XY model with disorder. We find that there is a first-order phase transition even for large disorder when the corresponding equilibrium transition is continuous. The low temperature phase is an anisotropic moving glass. {copyright} {ital 1997} {ital The American Physical Society}
