The Rhode Island Department of Transportation filed a motion to dismiss a lawsuit brought by the American Trucking Associations, Cumberland Farms Inc., M&M Transport Services and New England Motor Freight challenging the states truck-only tolls, arguing that they are asking the court to do something that it lacks jurisdiction to do.
