Summary
Dwell and Dormancy Reports give trucking companies a clearer picture of trailer utilization, helping fleet managers identify trailers sitting too long at customer locations, uncover equipment that has gone unused for months, and make more informed decisions about recovery, redeployment, billing, and fleet right-sizing. By combining satellite-based tracking with actionable reporting, TGI Connect helps turn raw trailer-location data into insights that can improve operational efficiency and reduce unnecessary fleet costs.
What's the Difference Between Dwell and Dormancy?
The two terms sound similar, but they measure different problems.
A dwell report tracks how long a trailer has sat at one specific location — a customer’s dock, a terminal, or a maintenance yard — beyond an expected or contracted window. Dormancy, on the other hand, looks at the fleet as a whole and flags any trailer that has recorded zero movement over a set period, typically 30, 60, or 90 days. Put simply: dormancy is fleet-wide inactivity, while dwell is location-specific overstay. A fleet manager needs both, because a trailer can fail one test without failing the other — a trailer might be moving between a handful of nearby yards (so it’s not “dormant”) while still sitting far too long at any one of them.
The Advantage of Dwell Reports: Recovering Assets and Enforcing Contracts
One of the most common — and costly — blind spots in trucking is the customer who quietly holds onto a trailer well past their contracted return window, sometimes using it as informal overflow storage. In some fleets, one or two large customers can end up holding 20–30% of total trailer assets past their return date without anyone noticing until a shortage hits somewhere else in the network.
Dwell reporting solves this by pairing time-on-site data with geo-fenced location tracking, giving fleet managers date- and time-stamped evidence of exactly how long an asset has been parked at a given location. That evidence does two things at once. First, it gives operations teams the proof they need to go back to a customer and either recover the trailer or bill for detention — TGI Connect’s platform can even automatically generate demurrage invoices based on captured dwell data, turning an idle asset into a billable one instead of a pure cost. Second, it removes the guesswork and awkward conversations that come from relying on driver reports or incomplete spreadsheets, replacing them with hard data that both sides can agree on.
The Advantage of Dormancy Reports: Finding the Trailers You Forgot You Had
Dormancy reports serve a different but equally important purpose: surfacing the trailers that have essentially disappeared from active use. Rather than looking at any single site, a dormancy report scans the whole fleet and flags every trailer with zero recorded movement over the selected window, then lays out the details a manager needs to act — which trailers haven’t moved, where they currently sit, how long they’ve been parked there, and the number of days since any activity was last recorded. Trailers that have gone dark for an extended stretch are often flagged outright as retirement candidates, giving fleet managers a ready-made starting point for decommissioning decisions instead of having to dig through the data themselves.
For large carriers with assets spread across multiple terminals and drop yards, these reports are often where the biggest surprises turn up — trailers that have been sitting untouched for months, quietly costing $900 to $2,000 or more per month in ownership and overhead costs while contributing nothing to revenue.
Most fleets believe they’re running at 80–85% utilization. When the actual tracking data comes in, the real number is often significantly lower. A dormancy report gives fleet managers the ability to see that gap clearly and act on it — whether that means redeploying an underused trailer to a busier lane, right-sizing the fleet by retiring the assets flagged as no longer earning their place or investigating why a piece of equipment went dark in the first place.
Why This Combination Matters
Used together, dwell and dormancy reports let a trucking company answer two questions that are surprisingly hard to answer with gut instinct alone: Is this trailer stuck somewhere it shouldn’t be? And Is this trailer being used at all? Feeding both data sets into a fleet’s truck-to-trailer ratio also helps operations leaders figure out whether that ratio reflects real operational need or is just the product of historical habit and assets that were never retired.
For fleets still relying on manual yard checks or scattered spreadsheets, the payoff of moving to automated dwell and dormancy reporting is straightforward: fewer trailers lost to customer sites, fewer dormant assets quietly bleeding money, and a fleet that’s sized — and priced — according to how it’s actually used, not how it’s assumed to be used.
Within TGI Connect’s reporting suite, Dormancy sits alongside Dwell, Yard Checks, Mileage, and broader Utilization reports as part of a single connected view of the fleet — giving managers one place to check both whether a trailer is stuck somewhere it shouldn’t be, and whether it’s being used at all.
