Discription of Events: Lady threw object at my vehicle after yelling and cursing because a vehicle was parked ahead of her and i didnt let her merge into the lane i was on. She didnt use her blinker so i paid no heed to her needing to merge. She took the time to rumage in her vehicle to find something to throw at my vehicle then merged infront of me. We were in traffic so none of it made a difference.
