All, I need your help, please.....this is true I was rear ended and I would like to know the impact force.... I was waiting for the car in front of me to turn left, so I had my foot on my brake, I was driving a 2004 Lexus RX330......call it 3500 lbs. A large truck was texting and driving....and without braking ran into the back of me @ 35-40 mph.....his truck is 17,000 lbs and he was carrying another 5,000 lbs of deliveries After the initial rear end crash, then my car was catapulted into the minivan in front of me trying to take a left....my car was totaled from the rear, and the front collision..... Can someone please tell me approximately the impact force that hit me from behind? I am not an engineer, just a guy with a bunch of metal staples and stitches in my head. Someone, please respond. Thank you very much!
