Will the insurance of the at fault driver be liable if your car was hit while it was stolen?

This is interesting, are you saying while your vehicle was stolen the thief got into an accident that was not his fault? That's unusual, the thief is generally driving so irratically and clearly At Fault, but in this case, (never had a claim like this), I'm really not sure, the argument could be made that the vehicle was being used in a felony therefore no recovery, however if the other person were negligent do they still not owe for their negligence? I know if a drunk driver (let's say), is at a stop sign, and is rearended, his 'drunkeness' didn't contribute to the accident, and he will (generally subject to the policy Wording and any state laws), be compensated for his loss by the vehicle that rearended him. File it with yours and the 'at fault' drivers policys. I would be interested to hear how that is handled if you would let me know.
