Man Possessed by Aliens Peels Off Face

There is an early 80's horror movie about alien possession that scared the pants off me.

A man is driving down a road late at night when he hits something. Later, he goes to the bathroom not feeling well. He looks at his reflection and sees a vein pulsating on his forehead, and starts to peel off his face like he's peeling an orange.

What movie is this?
