When filing a claim with your insurance company about an accident-related car repair, make sure that you know your claim number. This is especially important if it was caused by the other party. You may then submit proof of his/her fault and ask for a claim number so that you can utilize a rent-a-car for free while your vehicle is being repaired. Because you are the only one who has access to the claim number, you must do the claiming yourself. If you need assistance with language, ask your insurance agent if he can provide with an interpreter.
