(Providence, RI) -- As was promised, a lawsuit is being brought against Rhode Island's new truck toll system. The suit was filed Tuesday in federal court in Providence by the American Trucking Associations, of which the Rhode Island Trucking Association is an affiliate, Cumberland Farms, M-and-M Transport Services and New England Motor Freight against Rhode Island Department of Transportation director Peter Alviti, Jr. The parties claim the truck-only-toll system, in place on I-95, violates the Commerce Clause of the U.S. Constitution.
