Discription of Events: Driver tried to run my vehicle into the street by honking and practically pushing my vehicle onto a road with oncoming vehicles. We were both making a right turn out of a shopping plaza but there is traffic coming from the left that i was waiting to clear as i was going to the left most lane. Person honked and screeched vehicle behind me and cut me off and went nuts after we turned. I followed carefully and when he realized he started zig zagging and crossed across the street as if in a high speed pursuit to duck into a driveway and make an escape. I was just following to see if there were marking to report his driving to his company as it was a commercial vehicle with equipment racks and stickers on it. I took a few pics of his vehicle pulling out of where he lost me.
