Common carriers, such as bus companies, have a duty to ensure that drivers are proeprly trained to drive in a safe manner. In fact, the responsibilities that are placed upon common carriers by California laws are much greater than those that are placed on drivers who are operating personal vehicles. When you are injured in an accident while traveling on a common carrier, you will probably look into the possibility of seeking compensation.
One important factor that distinguishes a common carrier from an ordinary driver is that common carriers charge a fee for transporting people or goods from one location to another. Often, these common carriers are operated by a municipality.
