“Common carriers must carry passengers [or property] safely. Common carriers must use the highest care and the vigilance of a very cautious person. They must do all that human care, vigilance, and foresight reasonably can do under the circumstances to avoid harm to passengers [or property]. While a common carrier does not guarantee the safety of its passengers [or property that it transports], it must use reasonable skill to provide everything necessary for safe transportation, in view of the transportation used and the practical operation of the business.”
