Discription of Events: I believe this was someone who works for the state because of the type of license plate (circle on top and starts with 5). He was an older man. He cut me off so bad on the highway that I had to slam on my breaks. If I was not as alert it would have been a really bad accident. He clearly didn't check his mirrors or blind spots. He didn't even use a blinker to let me know he was coming into the lane.
