Hit unlicensed driver...my fault?

[rescuer87]

A couple months ago i rear ended an unlicensed driver on the highway and he slightly tapped someone else. We called CHP and they took care of everything. Some people have told me that the accident is automatically considered his fault since he had no license and no insurance. Is this true? Would this mean i wouldnt get a dmv point on my record? Thanks for any input.
