A tractor trailer hit my car, a BMW Z4 convertible, ct license plate, in the rear left, as I was moving slowly with traffic just before the overpass, right before I hit the tappanzee bridge as I was heading to NJ on Friday, August 1st, 2014, sometime between 11:50-1230pm. I believe it was close or about 12:20pm.my head slammed violently against the top of the wheel from the impact.I looked back after being hit and the driver agreed to pull over when there was room for him after going over the bridge to exchange insurance information. I wrote down his license plate, it was Tennessee U514217.I believe the # of the truck was 5318. The driver was a white male, about 40-45year of age.after I sped in front, I pulled over just over the bridge to the right where construction was taking place and I waited for the truck to pull in behind me. The trucker pulled up to the left of my car while he was still in the first lane, and he was moving at a snail's pace; his window was rolled down and he stared me in the face, curled his right hand into a fist, put it up to his neck, raised his right thumb, and dragged his right hand across his neck as if to say he'd cut my throat. He then yelled, "I got somewhere to be! do you want me to drive back up here after we exchange personal information, come to where you live, and cut your throat!" he had driven past me.I hesitated. I didn't know what to do., I got a cat scan and had my head wound looked at, and was diagnosed with a severe bruise to the head and received treatment for anxiety I was feeling from the accident and the hit and run threat. A month has passed and I am still feeling anxiety over this; not to mention my car has been damaged.I am looking to find the driver who hit my car and caused me the wound and constant anxiety I now suffer.
