Excessive Truck Weight: An Expensive Burden We Can No Longer Support

GAO provided a supplement to its report on the impact heavy trucks have on highway deterioration and problems with federal and state weight enforcement efforts. A questionnaire was sent to all states to obtain information on general highway data, weight laws, and enforcement efforts. Through the responses, data were compiled on state highway mileage, maintenance needs, the impact of heavy trucks on highway conditions, and the extent of state research on weight-related issues.
