We show that the resistivities perpendicular ρc and parallel ρₐ to the basal planes of different graphite samples show similar magnetic-field-driven metal-insulator transitions at a field Bc{~}0.1 T applied parallel to the c axis. Our results demonstrate the universality of the recently found scaling in ρₐ of graphite and indicate that the metalliclike temperature dependence of ρc is directly correlated to that of ρₐ. The similar magnetoresistance found for both resistivities, the violation of Kohler's rule, and the field-induced transition indicate that the semiclassical transport theory is inadequate to understand the transport properties of graphite.
