If you were not at-fault in the accident you should contact the at-fault's insurance company to make a claim. If you were the person at fault you will be responsible for your own damages and since you did not have insurance you will have to pay out of your own pocket.

To not cause problems with your credit report you will need to continue to make the payments on the car, even if the car is damaged or harmed so badly you cannot drive it. If you do not it could be repossessed and this would really put a black mark on your consumer credit report and make it difficult to buy a car in the future.

Once your car is repaired make sure to get it insured. You can get a fast, free quote here.
