What is the primary responsibility of common carriers according to the Constitution?

The primary responsibility of common carriers, as outlined in the Constitution and subsequent interpretations, revolves around their role in transporting specified goods and persons. This duty emphasizes the obligation of common carriers to operate in a manner that serves the public interest, ensuring that they provide reliable and non-discriminatory services to all individuals and businesses in need of transportation.

The definition of common carriers encompasses various modes of transportation, including railroads, freight services, and passenger transport. Their operations are typically regulated to maintain fair practices and protect consumers. By focusing on the movement of people and goods, common carriers play a vital role in facilitating commerce and connectivity within and between communities.

While other options mention specific responsibilities, such as transporting government officials or managing railroads, they do not capture the broader scope of the common carrier's obligations. The mention of telecommunications services further diverges from the traditional definition of common carriers, which is centered on physical transportation.
