  It is shown that the transport coefficients (self-diffusion, shear viscosity,
and thermal conductivity) of the Weeks-Chandler-Anderson (WCA) fluid along
isotherms exhibit a freezing density scaling (FDS). The functional form of this
FDS is essentially the same or closely related to those in the Lennard-Jones
fluid, hard-sphere fluid, and some liquefied noble gases. This proves that this
FDS represents a quasi-universal corresponding state principle for simple
classical fluids with steep interactions. Some related aspects such as
Stokes-Einstein relation without a hydrodynamic diameter and gas-to-liquid
dynamical crossover are briefly discussed. Simple fitting formula for the
transport coefficients of the dense WCA fluid are suggested.
