How much money do you get if you are in a car accident and it is not your fault?

You don't "get money" for being in a car accident.

If you are in an accident and not At Fault, it is the responsibility of the other person's insurance company to put you back into the same place you were before the accident. This would involve paying for the repairs to your vehicle, or giving you the value of the vehicle if it isn't repairable. Also they would pay for any medical bills incurred as a result of the accident.
