Driver of one of their trucks re-entered I70 (70 mph zone) right in front of me from the shoulder from a stop. I ended up swerving out of the lane when I realized that we couldn't stop despite being locked up. Fortunately, car in next lane also jacked their brakes and swerved. Missed the truck with a Honda sedan on it by inches at most. Incredibly careless driver, and they would not answer when I called multiple times. I understand mistakes but this was almost fatal. Occurred on 6/6/18 at around 3pm.
