Answer: Slow down and let the oncoming vehicle pass, then move left to allow at least three feet of space for the bicyclist. The handbook advises handling one danger at a time by letting the oncoming car pass first, then providing adequate space for the cyclist.
California Driver's Handbook, page 56: “Slow down and let the oncoming vehicle pass. When the vehicle has passed, move to the left to allow plenty of space (at least three feet) to pass the bicyclist.”
