I totaled a rental car in Texas. HELP!?

Hi. My car is in the shop being repaired by my insurance company after being flooded in a storm (my understanding is that this doesn’t count against me since i had no control over it). I’ve never been in a wreck before but I hit someone from behind in my rental car (Enterprise) and totaled it. I didn’t purchase their insurance but used mine instead (Farmers) because I’m stupid. What are the likely consequences. I have no money, no house, and lots of student loan debt. What can happen to me? Can they sue me? If they do and I don’t have money what happens to me?
Yeah, I have full cover insurance because my car in the shop isn’t bad off yet. So I’ll have to deal with the deductible and raised rates? That wouldn’t be so bad considering. Will defensive driving help? I got a ticket as well.

Car insurance question —-total loss reimbursement and car rental??? In Texas.?

My sister’s boyfriend was driving my sister’s car and was crashed into by a drunk driver and totalled her car. The insurance company is dealing with him, instead of her! I think this is extremely unusual! Anyways, moving on….They provided a rental for 3 days and have yet to pay the damages for the car. My questions are these…

1. Is there a policy that the insurance company pays for the rental until they pay the car reimbursement?

2. The car is actually worth more than the loan. The insurance company told my sisters boyfriend that they would not give more than 1,000 (the loan is 1200). The cars nada value is between 2,700 and 3,900. Are they supposed to pay the lesser of either the car value or the amount of the loan, I was under the impression that the insurance would pay the car value, so this all sounds fishy.

3. Are they required to give you enough to buy a replacement of equal value?

I would really appreciate any help clarifying these issues. Thanks!

One Way Car Rental-Texas to South Carolina?

I am going to South Carolina anytime in the next two weeks. I would like to pick up 7/24/09 and drop off 7/26. I live in Texarkana, TX and am going to Greenville, SC. We have an airport here in Texarkana, AR. I went to our local Enterprise and they do not do one-way rentals. Hertz said it would be over 0 a day??! It’s only at Enterprise?? Why the difference? Anyways, my other problem is that I am only 22. I need the car (preferably small SUV) to have enough room for my three boys (4, 19mths, 8ths) and our luggage for a weeks vacation. Any quick ideas for online reservations or should I just deal locally?
Jello? Is that some kind of joke?
