Definately. But - because you drove it away, and you drove it (partially) on the trip, they will say it wasn't from the accident. In any event, prepare to get an offer for scrap value and they'll total it. Which with what you are talking about, might be the best thing for you.
BTW - I have been living with 2 bulging discs for 13 years now. 6 of those as a commercial mover. With care and always rembering it's there, it's not abig deal.
