We have measured the electrical resistivity, thermoelectric power, Hall coefficient, and magnetoresistance (MR) on single crystals of PrOs4Sb12, LaOs4Sb12, and NdOs4Sb12. All the transport properties in PrOs4Sb12 are similar to those in LaOs4Sb12 and NdOs4Sb12 at high temperatures, indicating the localized character of 4f electrons. The transverse MR both in LaOs4Sb12 and PrOs4Sb12 tends to saturate for wide field directions, indicating these compounds to be uncompensated metals with no open orbit. We have determined the phase diagram of the field induced ordered phase by the MR measurement for all the principle field directions, which indicates an unambiguous evidence for the \ensuremathΓ1 singlet crystalline electric field ground state.
