As I was sitting at a red light I was rear ended quite forcefully and 2 of the 3 seatbelts released upon crash impact. Me, the driver hit my face on the steering wheel and my grandson in the backseat flew forward into the passenger front seat his twin brother was sitting in. I am also concerned that none of the airbags went off but the crash caused us to go forward in our seats as well as broken glass on back windows and tailgate.
