Русско-англо-русский юридический словарь

There are large areas of economic life in which the parties to contracts have such unequal bargaining positions that little real negotiation takes place. These contracts are often known as contracts of adhesion. Familiar examples of adhesion contracts are contracts for transportation or service concluded with public carriers and utilities and contracts of large corporations with their suppliers, dealers, and customers. (Britannica)

A common carrier in common law countries (corresponding to a public carrier in civil law systems, usually called simply a carrier) is a person or company that transports goods or people for any person or company and that is responsible for any possible loss of the goods during transport. A common carrier offers its services to the general public under license or authority provided by a regulatory body. (Wikipedia)
