Why There Is No Standard

The most useful sentence available on this subject comes from the regulator's own materials: there is no standard definition of detention time. For a software-oriented reference on recording work time, this background.

FMCSA states it directly, alongside the observation that little public data exists and that detention consistently ranks among drivers' top problems. A federal agency, describing its own field, saying the central term is undefined. For broader transportation and measurement context, see U.S. Environmental Protection Agency.

That is not an oversight waiting to be corrected. There are four reasons it persists, and understanding them is more useful than waiting for a definition.

Reviewed August 9, 2026.

One: detention is a residual

In FMCSA's framing, detention is what remains once loading, unloading and their associated tasks are subtracted from total time at the facility.

A residual cannot be measured directly. It is computed from other measurements, and it inherits every ambiguity in each of them. Define loading time slightly differently and detention changes without anything about the visit changing.

Any standard definition of detention would first require standard definitions of everything it is subtracted from, and those are equally contested.

Two: the boundaries are commercially load-bearing

An hour is worth roughly $50 to $100. Every boundary — arrival, check-in, door assignment, load start, paperwork, gate-out — moves money.

That means no party is neutral about where a line goes, and a standard would allocate cost between them. A definition here is not a technical matter; it is a price term wearing a technical hat, which is why it lives in contracts and why nobody has agreed one across the industry.

Three: the operations genuinely differ

A refrigerated load with temperature verification and a seal check is not a dry van drop. Industry data puts average dwell around 1 hour 54 minutes across fleets and 3 hours 16 minutes for refrigerated carriers.

A definition tight enough to be useful for dry van would misdescribe reefer, tanker, flatbed with tarping, and live-load produce. A single standard would either be too loose to settle anything or too specific to travel.

Four: nobody has jurisdiction, and nobody wants the measurement

FMCSA regulates safety, not commercial terms. The FMC regulates ocean carriers, and its rule reaches billing practices rather than definitions of time. There is no body with authority to define detention for domestic trucking, and no obvious candidate.

The FMC's approach is instructive: it did not define the time. It required the invoice to show how the charge was calculated, which puts the definition in the document rather than in the regulation.

What fills the gap

The two-hour convention. Dwell beyond two hours treated as detention. Not regulation, not derived from a study of loading duration, and the default in most rate confirmations because it is round and defensible.

Whichever system the stronger party controls. In practice the facility's gate record or the shipper's yard system, because those are the records that exist when a dispute arrives.

And silence. A great many rate confirmations say "detention after 2 hours" and stop, which resolves nothing. Every one of the four boundaries stays open.

What to do instead of waiting

Define it in the document, per lane. Start event, stop event, free-time allowance, rate, and which record is authoritative when two disagree. Four sentences.

Prefer events both parties can observe. Gate-in and gate-out from a system with a timestamp beat "arrival," which is an interpretation.

And measure your own operation before arguing about anyone's average. Published figures are too coarse and too contested to settle a specific lane, and your own gate data is not.

The upside of the gap

One thing worth saying, because the absence of a standard is usually presented as pure loss.

Because there is no standard, everything is negotiable. Free time, rate, start event, notification requirement, and what happens when the facility's system is down. A party that has read this page and drafts the terms has an advantage over one that assumes the two-hour rule is a law.

Most people on both sides assume exactly that.
