You can be held accountable for an accident if you are a co-signer for a vehicle. As a co-signer, you are responsible for the vehicle, too. So, as a result, you are responsible for those who drive your vehicle, for what your vehicle damages, and those who get hurt (in your vehicle or not). This ultimate responsibility is called 'vicariuos liability.' To protect yourself, make sure there is adequate liability insurance (property damage liability and bodily injury liability).
