I was driving on 83N earlier today between 4:40 and 4:50 p.m. About a mile or two before the Paxton St. exit, someone driving one of your pick-up trucks got behind me in the left lane. She was riding my bumper and tail-gating me, and it was making me very nervous. Very unsafe in any driving situation but especially unsafe during a period of time when traffic is very heavy. Her driving was totally unacceptable to me, considering I am 10 weeks pregnant with my first child. I couldn't catch a license plate number, but the person driving the pick-up was female with long hair and glasses. I couldn't see for sure, but I think she was a brunette. She eventually got off at the 283S exit. Seeing as she was driving a company vehicle at the time, I thought you should know that at least one of your employees is a really unsafe driver and is giving your company a bad name. To say I am upset about this is an understatement. There was absolutely no need for her to tail-gate. I was keeping up with the flow of traffic and even if I wasn't, that's still no excuse for this bad driving.
