Discription of Events: The guy was tailgating me but I couldn't go fast because there was a car in front of me. He proceeded to try to pass me on the right, but couldn't because there was a car in front of me, so he tried to move into my lane, nearly knocking me into the guardrail. I had to quickly maneuver so there wasn't an accident while my 9-year-old daughter was in tears, scared to death.
