Railway Express Agency v. New York (S.Ct. 1949)
Facts:
New York City prohibited advertising on business delivery vehicles unless the advertisement was for the owner’s business. P sold space on its trucks for advertising that was unconnected with its own business.
Issue:
Do practical road-safety regulations that discriminate against some motor vehicle operators violate the Equal Protection Clause?
Rule:
(Douglas, J.) When a classification is rationally related to the accomplishment of a valid objective and is of a type not barred by the equal protection analysis, the regulation does not violate the Equal Protection Clause.
