The female driver with seeing glasses, t-shirt and sweatpants approached me in traffic on Route 3 at Lowell/Chelmsford line exit 81c. She said I didn’t use my blinker. She ran to my window, and I put it up, and she tried to stop me from closing it. I locked my doors in panic, and I’m still upset about it. She called me the “n word and said I should go back to the cotton fields and I bet your dad left for milk and never came back because he was “*** me.” I asked her to take her finger out of my window so I could leave, and she took a picture of me with her left hand using her phone. I thought she was going to break my glass. I did a fake sneeze, and she took it out, so I put the window up. I left, and she threw a rock at my car. I’m too scared to give my name. I’ve never seen her in my life, and I don’t want to ever again. I’m really scared. I don’t have pictures as I was shaking trying to get her away.
