Discription of Events: He swerved into my lane on purpose to try and drive me off the road because i had no choice but to merge last minute due to a closed lane that snuck up on me. When i finally merged over he flipped me off and acted like a full blown baby because i HAD to merge over and he wouldnt let me in. He then caught up to me in traffic and swerved into my lane and then proceeded to try and cut me off practically hitting the front of my car and making me swerve into the right lane.
