“About thirty truckers in Brighton, Colorado, refused to move their rigs in protest of the high cost of diesel fuel, fuel shortages, and the fifty-five-mile-per-hour speed limit. Other drivers followed suit in Iowa, Illinois, Michigan, Nevada, Nebraska, Connecticut, and Delaware. In New Jersey, the governor had to call on the National Guard to remove blockading trucks. The truckers complained that higher fuel prices and lower speed limits were threatening their profits.”
