He  swerved to his left/ my right , yes --not to avoid me-- but because he was going about 75 mph on a curve and lost control.  He swerved and was coming toward me 3/4 side ways in my lane, toward me, so and I went to the center lane to avoid HIM. He ended up  hitting me on the right rear side of my truck. THe lady in the Acura whom he had passed had accelerated in panic and ALSO went to the center lane. So she ended up head-on with me in the center lane.
