Which of the following best defines a common carrier?

A common carrier is defined as an entity that is in the business of transporting goods or people for the public, and it is required by law to offer its services to anyone who wants them, without discrimination and without the right to refuse service. The key aspect of this definition is the legal obligation to transport and the accessibility to all members of the public.

In the context of funeral laws and transportation, common carriers provide necessary services that should be available to everyone, adhering to regulations that prevent refusals based on arbitrary criteria. This ensures fair access to transportation services during sensitive times, such as after the death of an individual.

The other options provided do not capture the essence of a common carrier. Transporting only under contract suggests limited availability and exclusivity, which does not align with the public service nature of common carriers. Operating solely for private clients indicates a restricted client base, which contradicts the common carrier’s role. Not requiring payment for transport does not apply either, as common carriers are entitled to charge for their services, though they cannot refuse service based on payment if the customer meets the standard terms and conditions.
