A bill re-introduced in Congress in mid-February would allow states to permit trucks weighing as much as 97,000 pounds to use Interstate highways within their borders. Currently, Federal law restricts trucks to a maximum weight of 80,000 pounds.
Advocates of the higher weight limit say that it would allow shippers to make better use of existing trailer capacity. They note that shippers now send trucks out with plenty of unused cargo space because their rigs have hit the weight limit; raising it, they say, would mean fewer trucks on the road and reduced fuel costs. They also point to a pilot program in two New England states that permit truck weights up to 100,000 pounds; two Senators from those states, Susan Collins (R-Maine) and Patrick Leahy (D-Vermont), say the program has been successful and should be made permanent.
They also argue that since most of America's major trading partners already allow heavier trucks on their highways, the U.S. is put at a competitive disadvantage thanks to higher shipping costs due to lower efficiency.
Not everyone buys the trucking industry's argument, however. Opponents of the move point out that heavier trucks cause significantly more damage to the roads they use. They also note that one-quarter of the nation's bridges are already rated either "structurally deficient" or "functionally obsolete," and that it would cost $188 million (in 2006 dollars) to bring these back up to snuff. Allowing heavier trucks on the highways, they argue, would only add to both the number of substandard bridges and the cost of repairing or replacing them. They also point to statistics that show that heavier trucks also make the roads less safe for others who use them.
