Hicklin v. Coney

Background

The Railroad Commission of South Carolina sued a private contract motor carrier for operating on public highways without required certificates and paying license fees. The carrier argued the rules denied equal protection and due process and interfered with interstate commerce because he did some out-of-state hauling. The South Carolina Supreme Court rejected these claims, and the U.S. Supreme Court reviewed whether the State could enforce its motor-vehicle rules as applied to private contract carriers.

Reasoning

The central question was whether the State may require private contract carriers to get certificates, pay reasonable license fees, and file indemnity bonds without violating the Constitution or unduly burdening interstate trade. The Court agreed with the state court: the State may reasonably regulate highway use, require bonds or insurance filings to protect the public, and set fees tied to vehicle carrying capacity as compensation for road wear. The state court’s interpretation—saying the statute does not force private carriers to become common carriers or to carry cargo insurance—controlled the outcome.

Real world impact

The decision lets South Carolina and similar States enforce licensing, bonding, and size/weight rules for trucks, including fees that reflect vehicle capacity. Limited exemptions for farmers, dairymen, and specified lumber haulers are permissible because they are narrow, seasonal, or for specific short routes. The ruling largely affirms the State’s practical ability to regulate and collect fees for highway use while leaving detailed enforcement and limits to state interpretation.

Dissents or concurrances

None are discussed in the opinion; the Court affirmed the state court’s judgment without separate disagreement or concurrence in the published text.
