Single top production processes are usually regarded as the ones in which Vtb can be directly measured at hadron colliders. We show that the analysis of the single top rapidity distribution in t-channel and tW production can also set direct limits on Vtd. At LHC with 10 fb^\ensuremath-1 at 14 TeV, the combined limits on Vtd may be reduced by almost a factor of 2 when the top rapidity distribution is used. This also implies that the limits on Vtb can also be reduced by 15%, since both parameters, as well as Vts, must be simultaneously obtained from a global fit to data. At Tevatron, the exploitation of this distribution would require very high statistics.
