Discription of Events: Driving East on 547, November 14th at 7:08am, their lane was merging, mi e went straight...instead of yielding they honked and tried to run me off the road until I stopped and let them go in front (I had the right of way), then proceeded to go 15 mph below the speed limit as if to punish me , randomly slamming on the brakes (no one was in front of them).
