Congress debates raising the 80,000 pound truck weight limit

Congress set the current 80,000-pound weight limit for trucks on Interstate highways in 1991. For years proponents of raising the limit have argued that it would reduce the number of trucks on the road, shipping costs, and congestion. On the other side of the argument are those who believe these benefits are outweighed by the fact that heavier trucks are more difficult to control and stop, and that heavier trucks cause greater damage to roads and bridges.
