We present a study of the electrical and thermal conductivities of the d-density wave (DDW) state in an external magnetic field B in the low temperature regime and in the presence of impurities. We show that in the zero temperature limit, T→0, the Wiedemann-Franz (WF) law remains intact. For finite T the WF law violation is possible and it is enhanced by the external field.
