Discription of Events: I was on a one way road, it was my right of way, I stopped and allowed a pediatria to cross. As soon as the pedestrian had finished crossing I safely proceeded to go when this middle aged man in his truck speeds up and tries to cut me off from the side, I beeped at him because he could have created a dangerous accident by not being aware he can not just cut in front of someone in their right of way. He beeped right back and sped up behind me. There was a stop sign and the lanes switched into 2, one going straight and one turning right, he sped past me and beeped again, I was behind his car now that he cut in front of me and when the light turned green, he did not move on purpose disturbing traffic and causing an un safe scene for other drivers.
