We examine the possibility that direct dark matter detection experiments find
decay products from sterile neutrino dark mater in $U(1)_{B-L}$ and $U(1)_R$
models. This is possible if the sterile neutrino interacts with a light gauge
boson and decays into a neutrino and the light gauge boson with a certain
lifetime. This decay produces energetic neutrinos scattering off nuclei with a
large enough recoil energy in direct dark matter detection experiments. We
stress that direct dark matter detection experiments can explore not only WIMP
but also sterile neutrino dark matter.
