Discription of Events: Driver was speeding and constantly changing lanes with no signal. Driver got angry when I had to change lanes and got in front of him. He then proceeded to tailgate me, flash his lights, and then got beside me and tried to come over into my lane. He rode directly beside me and kept swerving into my lane, causing me to have to swerve just to get out of his way. When he was unable to get over, he rode along beside me and made rude gestures towards me.
