Rate coefficients for rovibrational transitions induced in HD by collisions with He are presented. Full quantum mechanical treatment has been used with the interaction potential surface calculated by Muchnick & Russek (\cite{muchnick:russek}). The vibrational v = 1 -> 0 quenching rates of HD due to various perturbers are compared up to temperatures of 1500 K. The influence of vibrationally excited channels on the pure rotational excitation cross sections is shown to be negligible.
