I was driving down the highway going 70 mph, a truck was in the lane right next to me. He had been there for a while and was going the same speed as me. Suddenly the entire van feels like it is shaking, like its going to break down right there.I hit the brakes, glance down at my dash board, and then glance back up. The truck has swerved completely into my lane and just as quickly swerves back into the other lane. The van is suddenly completely normal and doesn't act up again.
If I had not hit my breaks right at that moment that truck would have hit me.
