Like most States, California has laws dealing with impeding the flow of traffic. However, it is entirely subjective both from enforcement and conviction standpoints, and the only definitive laws deal with the left-most lane. In other words, doing the speed limit, or even a bit below the speed limit (meaning 55 MPH), in the right-hand lane, is perfectly legal and defensible.

Here's an article from the California Chronicle that explains it all:
