  We study the effects of a modest V+A admixture strength in $b\tou$ current in
the decay $B \to\rho l \nu$. We have shown that the decay rate, lepton
forward-backward distribution asymmetry $A_{FB}$ and polarization ratio are
sensitive to the admixture. Future experimental studies of the decay at BaBar
and BELLE could clarify the chirality of $b\to u$ current and might reveal
hints for New Physics with right-handed quark currents.
