At about 4:30 PM I was merging after the traffic light on Route 33 just past Travel Authority Truck stop headed into Stratham area. I was allowing space for a 1 for 1 merge in front of me when a woman came flying up on my driver side blaring her horn. Scared me and caused my 3 year old daughter in the back to start crying. She put down her cell phone and I saw her gesturing in my rear view mirror. She appeared belligerent and tailgated me through two turns consecutively. I was about to go to the police station when she turned off.
