We apply a previously developed scheme to consistently include the twist-3 distribution amplitudes for transversely polarized rho mesons in order to evaluate, in the framework of k(T) factorization, the helicity amplitudes for exclusive leptoproduction of a light vector meson, at leading order in alpha(s). We compare our results with high energy experimental data for the ratios of helicity amplitudes T(11)/T(00) and T(01)/T(00) and get a good description of the data.
