Actually, we had a lady, in a red car, slam on her breaks in the slow lane to a complete stop, and we had to swerve around her on the shoulder to avoid hitting her. There was nothing in front of her, no reason for her to stop...she just did, then was looking at us as we swerved around her. We were not tailgating, actually was a little ways behind her but it is hard to avoid hitting something that all of a sudden stops when you are going 60. I can't imagine being a huge truck and trying to all of a sudden stop and trying to avoid hitting others as well. You should maybe be a little more sensitive to the situation beings you weren't in it! Prayers for all!
