Discription of Events: There was no room to pass me, but they rammed their way over and I was forced to slam on my breaks and swerve off the freeway next to the cement divide. They then continued to step on their breaks and not allow to me change lanes without their offense. They attempted to push me off the road and then again into a semi truck. I was very frightened and pulled out my phone for a picture of their license plate. They then left me alone and continued on in the fast lane to their destination.
