In some states where an ambulance is running through a red light for "in duty" and causes an accident, the ambulance company can not be held liable for negligence as state statutes provide immunity to the ambulance company and its employees because the ambulance company was acting on behalf of the government to protect its citizens.

Other than a gross negligence claim, what claim can be brought against the ambulance company for its negligence where its injured passengers are harmed from the ambulance's negligence?
