Bigger tractor-trailers may have some advantages, but what’s in it for you?

---

Dueling proposals concerning heavier tractor-trailer combos on federal highways were introduced in the U.S. House in March, rekindling long-running debates over truck safety, aging infrastructure and growing congestion.

What you don’t hear in the arguments is how this will affect drivers, because ultimately the issue is more about competition than the pros and cons being bantered about.

H.R. 1799, or the Safe and Efficient Transportation Act of 2009, would allow tractor-trailer combinations to weigh up to 97,000 pounds on the National Highway System with the addition of an extra axle on the trailer. The bill is endorsed by the American Trucking Associations and shipper organizations.

Introduced prior to the above bill, which did not amend trailer lengths, H.R. 1618, or the Safe Highways and Infrastructure Preservation Act, would limit trailer length on the National Highway System and extend those limits to other roads as well. It would prevent states from enacting new laws to allow trailers longer than 53 feet. Tractor-trailer maximum weight would remain at the current 80,000-pound limit. It has the support of the Truckload Carriers Association, the Owner-Operator Independent Drivers Association and so-called safety advocates.

H.R. 1799 would increase efficiency and reduce emissions, congestion, truck crashes and road maintenance, according to its supporters.
