Slow down, dive to the shoulder, whatever it takes that has an acceptable risk.
I fully agree that all drivers/cyclists/whatevers have a moral obligation to do what they can to prevent a collision. However, here in Oregon there is no legal obligation to do so. That said, the only person I ever heard of applying our perverse vehicle code in this way and getting away with it eventually did it again, only in that later instance he was wrong and a female cyclist is dead because of that. Unfortunately, our DA is notorious for ignoring these sort of things and he got a mere slap on the wrist.
