The Federal Highway Administration will look at eight types of tractor-trailer combinations in its comprehensive study of truck sizes and weights.

The agency will compare six variations to two familiar control configurations, the 5-axle, 80,000-pound workhorse, and the 6-axle, 80,000-pound twins combination of a tractor pulling two 28-foot or 28.5-foot trailers.

The first variation will be the 5-axle rig with a gross weight of 88,000 pounds.

The second will be the 6-axle, 97,000 unit that some in the industry are promoting as the logical expansion of the long-time federal size and weight limits. The third will be a 91,000-pound version of that unit.

The fourth will be a 6-axle, 80,000-pound combination of a tractor pulling two 33-foot trailers.

The fifth: a 7-axle, 105,500-pound combination of tractor and three 28-foot or 28.5-foot trailers.

And the last will be a 9- or 10-axle, 129,000-pound combination with three 28-foot or 28.5-foot trailers.

These details emerged from a webinar the agency conducted Wednesday. Look for more news from the webinar on Thursday.

The agency is halfway through a two-year study that is intended to give Congress the information it needs to decide on possible changes in current standards. The study is due to be finished by next November.

The agency originally intended to take comments on the study until Jan. 3, but now has extended that deadline to Jan. 17.

    Yeah just what the public ordered. The roads are falling apart, Bridges falling down, The whole country is broke from being over taxed. And we need to add more tonnage to the Highways. Not to mention we will be spending more on Equipment just to have some Broker offer us another Great Paying load that will get you home for 75 cents a mile including fuel surcharge.

    We can be more productive, some carriers move light loads and want more cube, some would like more weight. These LCV's are for the companies with terminals and separate city operations, let them study it. Drive a way operations can run 97 feet long, yet I am still restricted to 82, 75 plus 3 feet over the front and 4 feet overhang on the rear. The auto haulers with a high mount trailer get hassled for having cars overhang beyond 53 feet, it is a specially designed trailer, but some states don't agree. WA, MN, MI, CT and others. I am disappointed they did not include a "B" train for a tank, bulk or flatbed operation.
