A Long History Shapes the Size and Weight Study

The Federal Highway Administration should have a pretty good idea of what to expect as it proceeds with its comprehensive study of truck sizes and weights. The study, which Congress will use to decide on possible changes in current standards, is the latest in a long line of similar research.

In fact, the study of truck size and weight regulation is an industry unto itself.

Since 1978 there have been more than 150 significant research projects on the issue, according to a 2011 directory prepared by the Texas Transportation Institute.

These studies cover nearly a dozen separate elements, each a highly specialized area of research in its own right.

They cover the engineering disciplines of the infrastructure itself: pavement surfaces and substructures, bridges and highway geometry.

They cover the economics of modal share, or the possibility of shifting freight volumes and distribution patterns within the trucking industry as well as between trucks and railroads.

They cover the highly charged and contentious issue of safety.

They cover costs and benefits, congestion, highway financing, environmental issues and public opinion.

To this the research has added perspectives from the federal level and the state level, as well as what other countries are doing with sizes and weights.

18 Months to Go

FHWA has 18 months left in a two-year project to pull all this material, plus new research, together into a peer-reviewed report ordered by Congress last year.

Some trucking and shipping interests had been hoping to get a change in the current standards through Congress in last year’s highway bill, MAP-21. But their proposal to allow states to permit 6-axle, 97,000-pound combinations on their Interstates ran into stiff opposition from traditional opponents in the safety advocacy community, rail industry and driver circles, so they had to settle for this study.

The agency will study three configurations: the current 5-axle, 80,000-pound standard; a 5-axle, 88,000-pound combination; and the 6-axle, 97,000-pound combination.

It is looking for help choosing an additional three configurations, possibly including twin 33-foot trailers, Rocky Mountain Doubles, Turnpike Doubles and triples.

On Wednesday this week FHWA hosted the first of four public sessions it plans to hold as part of the drafting process.

“We know there are diverse views,” said Jeffrey Paniati, executive director of the Federal Highway Administration, as he opened the session.

He was right about that. What emerged from the four-hour session attended by about 400 in person and online was an airing of familiar talking points and contentions by many of size and weight constituents.

Owner-operators, who generally are leery of raising the size and weight limits, raised long-standing concerns about the competitive impact on them if they had to buy new equipment.

Tilden Curl, an independent associated with the Owner-Operator Independent Drivers Association, said he would have to change out his entire fleet to adapt to new equipment, while larger carriers could focus on just a portion of theirs.

Scott Grenerth, another independent allied with OOIDA, urged the agency to look closely at road surfaces on ramps and just before stop lights, where the friction of heavy trucks can cause pavement to bend and buckle.

Also apparent were the longstanding contentions between the safety advocacy community, which adamantly opposes size and weight increases, and trucking interests that say increases can be safe and beneficial.

Stephen Owings, president of the safety advocacy group Road Safe America, cautioned the agency not to believe the trucking industry’s contention that bigger trucks will lead to relatively fewer trucks.

“We can’t make the assumption that if we add weight we reduce trucks,” he said. “Whenever trucks have gotten heavier there have been more of them.”

This drew a response from John Runyan, executive director of the Coalition for Transportation Productivity, which is pushing for the permissive 6-axle, 97,000-pound standard.

“It’s critical that you interview shippers,” he told the agency. Many shippers support the higher weight standard and argue that if they had it they could reduce the number of trucks they use.

To which owner-operator Tilden Curl responded, “If you’re going to interview shippers, you also should interview drivers. Any time you increase weight you increase responsibility and the risk of decreasing safety.”

Runyan also urged the agency to consider the way the industry currently operates, referencing the practice of loading 100,000-pound shipping containers on 5-axle combination chassis.

“Six axles would be far better than five for that situation,” he said.

John Lannen of the Truck Safety Coalition, which opposes bigger trucks, replied, saying that a 97,000-pound truck will never be safer than an 80,000-pound truck.

Runyan pointed out that what his group wants is a permissive standard: let the states decide individually whether or not to allow the bigger trucks. The point is to clear the way for the creation of freight corridors, he said.

Lannen said that if the agency considers the permissive approach it also must consider the pressure that may put on surrounding states.

One truckstop operator in the audience urged the agency to consider the impact of larger, heavier trucks on his business: they could force him to change the geometry of his lot and impact his pavements.

Dave Osiecki, senior vice president of policy and regulatory affairs at American Trucking Associations, said the agency could sharpen its bridge analysis by looking at the “practical” routing that would emerge from a change in the standards.

“You can make reasonable assumptions on routes based on costing,” he said.

Randal Mullett, vice president of government relations and public affairs for Con-way, suggested that the agency look at the impact larger trucks might have if safety were analyzed on a ton-mile basis rather than the standard mileage basis.

“If you can eliminate miles you can improve safety in relative terms,” he said.

Agency officials at the session said their intention at this point is to get suggestions on what should be in the study and how best to carry it out.

“We will not form policy but will summarize the data for Congress,” Paniati said. “We will consider everything from lives to livelihoods.”

More public sessions are scheduled for next fall, winter and spring in preparation for the final report, due to Congress in November 2014.

    First let me say that I have been working in the Trucking Industry well before, deregulation. I worked both as a Trucking Co. owner and operator and as a mechanic. I noticed that all of your diagrams show COE trucks! I personally think that something should be done about these "Cowboys" I call them that is out here With 40 FT plus long Tractors pulling 53 ft foot trailers. There is NO way that they can meet current length laws. That is a DANGER in my opinion and from Experience. This type of Owner-Operators also in my caliculation wastes enough fuel to heat many houses in New England States a winter! They do to much Dead Heading! Compare there empty miles to a Larger more cost efficient Company such as several of the larger Co. that I won't mention. There is ABSOLUTLY no use for one of these COWBOYS to be running up and down the road with a camper sized "sleeper", is that what they call it? And Engine Horsepower, Let them change a few gears! They don' t need 550 plus Horsepower. A waste of fuel! Even they may argue that these new engines get better fuel mileage, You are just talking 5.5 in 1977 to maybe 7.0 now. When you factor in the Cowboy waste they are actually using MORE fuel. Gentlemen I hope you will consider the information I have presented. I have not been sitting behind a desk the last 50 years, I have seen all this happen right before my eyes. Do the math on Cowboy dead heading and see if I am right! With all the GPS capabilities these days this is not fair to the many Americans that need that fuel to heat there homes. GPS the large CO. to coordinate loads and eliminate fuel waste. Intra state could of course be exempt because the waste is Cowboys dead heading long distances Interstate to get a load. This article was right These Cowboys just figure the money they will have in there hand that week, not at the end of the year. I have had many of them whinning for me to repair there engine because they didn't have the money for repairs after operating for S
