Universal Trailer Pools

What if the freight industry didn't need more trailers? What if it needed better access to the trailers it already has?

That's the idea behind the universal trailer pool, and its time may have arrived.

In his article, “Universal Trailer Pools—The quest to improve operational efficiency,” Mohan Krishnamurthy, Ph.D., argues for moving beyond traditional trailer pools to a model where trailers can be shared across carriers and shippers.

Traditional trailer pools solve an important problem. By staging trailers at shipper facilities, carriers enable drop-and-hook operations that separate a driver's schedule from a facility's loading schedule. Drivers spend less time waiting. Shippers gain flexibility. Freight keeps moving.

But there is an inherent limitation: those trailers generally belong to one carrier and are available only to that carrier. So while a yard may be full of trailers, another carrier moving freight nearby can still be short on equipment.

This inefficiency is what a universal trailer pool is designed to address.

And three years after Krishnamurthy raised the idea, trailer-market transaction data makes an even stronger case.

What Is a Universal Trailer Pool?

A universal trailer pool is a shared network of trailers that multiple carriers or other transportation providers can access, rather than reserving them exclusively for one fleet.

The concept is straightforward: instead of every fleet maintaining enough trailers to cover every potential surge, lane, and customer need, excess equipment can become accessible to other qualified operators when and where they need it.

For trailer owners, that means idle equipment can become productive. For carriers, it means accessing trailer capacity without purchasing equipment for every potential need. For brokers and shippers, it means a larger pool of equipment that can potentially be matched with freight.

In other words, trailer capacity begins to behave more like freight itself: dynamic, distributed, and available across networks.

The Problem Isn't Necessarily a Lack of Trailers

One of the most important distinctions in the universal trailer pool discussion is the difference between equipment supply and equipment availability.

A trailer can exist and still be effectively unavailable.

It can be sitting in the wrong market. It can be dedicated to a private pool. It can be idle inside a fleet that doesn't currently need it. Or it can simply be invisible to the carrier that needs equipment a few miles away.

That's why adding more trailers alone doesn't solve the industry's utilization problem.

The Federal Highway Administration's MV-11 trailer and semi-trailer registration table remains temporarily suspended, leaving the industry without a current national public dataset for trailer registrations. At the same time, fleets continue investing in equipment. FTR reported that the 2026 trailer order season finished at 212,116 units, up 13% from the prior season. More equipment is entering the system - the larger opportunity is making the equipment already in that system work harder.

REPOWR's Data Shows Why Shared Capacity Matters

REPOWR's State of Trailer Utilization H1 2026 analyzed 23,816 marketplace reservations to understand how carriers are actually accessing and moving trailer capacity.

One number stands out in the context of universal trailer pools:

83.3% of REPOWR rentals in H1 2026 ended in a different market than where they began.

That percentage has increased every year:

• 75.0% in 2023
• 80.8% in 2024
• 82.9% in 2025
• 83.3% in H1 2026

Why does that matter? Because freight is directional.

A trailer doesn't necessarily finish where its owner needs it next. As thousands of individual loads move through the freight network, equipment naturally accumulates in some markets while demand builds in others.

A closed trailer pool can't easily correct that imbalance because its optimization boundary stops at the edge of the fleet, but a connected pool can create another option: the trailer's next productive move doesn't necessarily have to be for its owner. It can serve another carrier's freight, generate revenue along the way, and potentially move closer to where the owner needs it next.

That's a fundamentally different way to think about trailer repositioning.

Trailer Demand Is Becoming More Immediate, Too

Location isn't the only challenge - timing matters, too.

REPOWR's H1 2026 data found that 77.2% of trailer reservations were fulfilled the same day, with an average of just 9 hours from reservation to pickup. For same-day reservations specifically, the average was only 1.27 hours.

That behavior tells us something important about trailer capacity: carriers frequently aren't looking for equipment six months from now - they need a trailer because they have freight now.

That makes maintaining excess equipment everywhere an expensive way to solve an unpredictable problem.

A shared network approaches the problem differently. Instead of asking, “Do I own a trailer in this market?” the operational question becomes:

“Is there an available trailer in this market that I can use?”

The distinction sounds small, but at network scale, it isn't.

From Universal Trailer Pool to Universal Trailer Network

The ultimate goal should be a connected trailer network that can identify available capacity wherever it exists and match that capacity with demand.

That requires several things working together:

• Visibility. Where is the trailer? Is it available? What type of equipment is it?
• Connectivity. Can data flow between telematics providers, TMS platforms, ELDs, and other systems without creating another manual workflow?
• Trust. Who is taking possession of the equipment? Are the carrier, insurance, and interchange requirements verified?
• Access. Can qualified carriers actually reserve equipment when they need it?
• Intelligence. Where should equipment go next based on forecasted supply and demand?
• Execution. Once the network identifies an imbalance, can it actually do something about it?

That last step is particularly important. The transportation industry has become very good at producing visibility. Fleets have dashboards showing trucks, trailers, loads, and locations, but knowing that 20 trailers are sitting in an oversupplied market doesn't move them.

Visibility tells you there's a problem. Execution solves it.

The Economics Make Better Utilization More Important

The cost of inefficiency is also rising. According to the American Transportation Research Institute's 2026 Analysis of the Operational Costs of Trucking, the average cost of operating a truck reached a record $2.336 per mile in 2025, up 3.4% year over year. Excluding fuel, costs increased 4.2%.

Against that cost environment, empty moves and idle assets become increasingly difficult to ignore, and REPOWR's data shows the operational side of that equation - approximately 30% of trailers listed on the marketplace are in low-demand markets or need to be repositioned faster than a traditional rental listing alone can solve.

Moving those trailers reactively isn't free, either. REPOWR's operational data puts the average reactive repositioning move at approximately $500 before staff time is included.

The answer isn't simply to own more equipment, but to create a larger addressable network for the equipment already available.

Sharing Is Only Half the Equation

This is also where the universal trailer pool concept has evolved.

Sharing makes capacity accessible. Optimization makes it useful.

Imagine a fleet with trailers distributed across 20 markets. Some locations have excess capacity. Others are likely to run short next week.

Historically, a trailer manager might discover the imbalance after it becomes a problem, find a driver or broker to reposition equipment, pay for an empty move, and update a spreadsheet.

A connected trailer network changes the equation.

Available trailers can be exposed to qualified demand, telematics can provide location information, marketplace activity can reveal where carriers need equipment, historical transaction data can identify recurring demand patterns, and optimization technology can identify network imbalances before they become urgent.

And rather than paying to move an empty trailer, an operator can look for opportunities to move it productively while it repositions.

That is the transition from trailer sharing to trailer optimization.

Does a Universal Trailer Pool Mean Fleets Stop Owning Trailers?

No.

A shared trailer network doesn't require eliminating private fleets or fleet ownership, rather, it creates another layer of flexibility.

Fleets can maintain the equipment they need for core operations while making excess capacity available when it isn't needed. Carriers can supplement their own fleets during surges, seasonal demand, or geographic imbalances; brokers can access equipment to support power-only capacity, and trailer owners can earn from equipment that would otherwise sit idle.

The objective is universal access to available capacity.

What Are the Benefits of a Universal Trailer Pool?

At scale, a connected trailer network can help the freight industry:

• Increase trailer utilization. Equipment sitting idle within one fleet can serve productive demand elsewhere.
• Reduce unnecessary capital expenditures. Carriers can access incremental trailers without buying enough equipment to cover every peak.
• Reduce empty repositioning. Shared demand creates opportunities to move equipment productively toward markets where it is needed.
• Expand power-only freight opportunities. Tractor capacity and trailer ownership no longer have to be paired as tightly.
• Respond faster to demand. Carriers can access trailers near the freight rather than waiting for owned equipment to arrive.
• Generate revenue from idle assets. Trailer owners can turn underutilized equipment into an earning asset.
• Create a more resilient freight network. Capacity can move across organizational boundaries instead of remaining trapped inside isolated pools.

The Bigger Opportunity: Make Equipment as Flexible as Freight

Krishnamurthy ended his discussion of universal trailer pools by asking whether the model could fundamentally shift the industry toward power-only freight, allowing carriers to benefit from lower capital requirements and shared equipment risk.

We think that question is worth continuing, but we'd take it one step further.

The future isn't simply a universal pool of trailers. It's a universal network of trailer capacity - one where equipment can be discovered, shared, moved, and optimized across organizational boundaries.

The freight industry already operates as a network. Loads cross carriers, brokers, shippers, warehouses, and markets every day, so trailer capacity should be able to do the same.

That's how we get more freight out of the equipment already on the road, that's how idle trailers become earning assets, and that's how the industry can share more, move more, and earn more.
