Held. No, state regulations limiting width and weight of trucks operated on state highways does not violate the Constitution’s commerce clause. The Supreme Court of the United States (Supreme Court) first pointed out that Congress decided not to regulate the weight and width of motor vehicles and left that power to the States. The Supreme Court also recognized that South Carolina had a great local concern in passing its regulations. Further, since South Carolina’s regulations were nondiscriminatory, they were appropriate.
Discussion. The state has a primary and immediate concern in taking care of their highways. The state may impose nondiscriminatory restrictions with respect to the character of motor vehicles moving in interstate commerce as a safety measure and as a means of securing the economical use of its highways.
