An out-of-service (OOS) order is a federal enforcement action that prohibits an entire carrier from operating until it corrects a serious deficiency — a far broader stop than a single truck being placed out of service at a roadside inspection. A carrier under an active OOS order cannot legally haul, period. This guide explains what triggers a carrier-level OOS order, how it differs from a revocation and from roadside out-of-service designations, how to read its status, and why it's a hard stop in any vetting workflow.
An out-of-service order is a federal enforcement action that prohibits an entire carrier from operating until a serious deficiency is corrected — distinct from a single vehicle or driver being placed out of service at a roadside inspection, and distinct from a revocation, which removes the operating authority entirely. A carrier under an active OOS order cannot legally haul any freight. The federal record publishes the order date and a rescind date (blank while the order is still active), so an active order is readable as a present-tense prohibition. Tendering to a carrier under an active OOS order is never a judgement call — it's a hard stop.
A carrier-level out-of-service order is issued when the federal regulator determines that allowing the carrier to keep operating poses a serious risk. The most severe form is an imminent-hazard order, issued when a carrier's operations present an immediate threat to public safety. Other OOS orders follow from a carrier's failure to comply with a regulatory requirement — for example, failing a compliance review, refusing or failing a required audit, or not correcting deficiencies the regulator has already flagged.
The unifying theme is that the order is aimed at the carrier as a whole, not a single vehicle or driver. Where a roadside inspector can place one truck out of service for a brake failure, a carrier-level OOS order shuts down the entire operation until the underlying problem is resolved and the order is lifted.
A carrier operating under an active out-of-service order is operating illegally. Any carrier that continues to solicit freight while under an active order is, by definition, a carrier ignoring a federal shutdown — exactly the kind of operator to avoid, and a common precursor to a reincarnation flip under a new MC.
Three different things share the 'out of service' language, and conflating them causes real errors. Here is the distinction:
A carrier can be under an active OOS order without being revoked, and vice versa. The OOS order is a 'stop until fixed' state; the revocation is a 'authority gone' state. Both prohibit operation; they differ in whether the authority itself survives. Reading them correctly matters because an OOS order can be lifted (rescinded) when the carrier complies, whereas a revocation requires re-registration.
The federal record publishes out-of-service orders with two key dates: the order date (when the order took effect) and the rescind date (when it was lifted). The rescind date is the field that tells you whether the order is active. A blank rescind date means the order is still in force — the carrier is currently shut down. A populated rescind date means the order was resolved and lifted; the carrier was under an order historically but is operating again.
Knowhaul ingests the federal out-of-service-order feed weekly and stamps each carrier with a currently-out-of-service flag computed from the rescind date, so the active/resolved distinction is readable on the carrier card without parsing the raw filing.
A carrier that was under an out-of-service order in the past, with the order since rescinded, is legally operating again — the order is no longer a bar. But the history is still context worth reading. A carrier that has been shut down and reinstated once is a different risk profile from one that has never been ordered out of service, and a carrier with multiple historical OOS orders is showing a pattern of falling out of compliance badly enough to be shut down.
The right way to read a resolved order is as a data point in the carrier's overall compliance trajectory, not as a current disqualifier. Pair it with the authority history, the revocation record, and the safety profile to see whether the carrier's compliance is improving or deteriorating over time.
Unlike most vetting signals — which are judgement calls weighing relative risk — an active out-of-service order is binary. The carrier is legally prohibited from operating. There is no broker risk assessment that makes tendering to a shut-down carrier acceptable: if the carrier hauls your load, it is doing so illegally, your insurance and liability posture is compromised, and you have selected a carrier the federal regulator has explicitly ordered off the road.
This is also where the OOS order connects to fraud. A carrier under an active order that keeps soliciting freight is a strong reincarnation-flip candidate — the operator may already be standing up a new MC to escape the order. An active OOS order on a carrier, or on a carrier linked by shared identity to the one you're evaluating, is one of the highest-priority signals in the whole vetting workflow.
An out-of-service order prohibits a carrier from operating until it corrects a specific deficiency, but the operating authority can remain on file — it's a 'stopped until fixed' state, and the order can be rescinded when the carrier complies. A revocation removes the operating authority entirely; the carrier must re-register to operate again. Both prohibit operation, but the OOS order is reversible by fixing the issue, whereas the revocation requires starting over with a new authority. A carrier can be under an active OOS order without being revoked.
No. A roadside out-of-service designation stops one truck or one driver at one inspection for a serious violation — the carrier keeps operating its other equipment. A carrier-level out-of-service order is an enforcement action that shuts down the entire carrier until a deficiency is corrected. The roadside designation feeds the carrier's out-of-service rate (covered in a separate guide); the carrier-level order is a present-tense prohibition on the whole operation.
Read the rescind date on the order. The federal record publishes both the order date (when it took effect) and the rescind date (when it was lifted). A blank rescind date means the order is still in force and the carrier is currently prohibited from operating. A populated rescind date means the order was resolved and the carrier is operating again. Knowhaul computes a currently-out-of-service flag from the rescind date and stamps it on the carrier card, so you can read the active/resolved status without parsing the raw filing.
Yes. An out-of-service order is lifted (rescinded) once the carrier corrects the deficiency that triggered it. A carrier with a resolved order — a populated rescind date — is legally operating again. The history is still worth reading as context: a carrier that has been ordered out of service and reinstated has a different compliance trajectory than one that never has, and multiple historical orders signal a pattern. But a resolved order is not a current bar to tendering.
Because an operator whose carrier is under an active out-of-service order has a strong incentive to keep operating illegally or to flip to a new MC that doesn't carry the order — the reincarnation pattern. A carrier under an active order that is still soliciting freight is ignoring a federal shutdown, and an active order on an identity-linked carrier (sharing an officer, phone, or address with the one you're evaluating) is a high-priority reincarnation signal. Our reincarnated-carrier guide covers that connection in depth.

A reincarnated carrier is one whose authority was revoked, then re-emerged under a new MC to shed the enforcement record. Learn the revocation-flip pattern and the public signals that expose it.
Authority history is the single strongest fraud-detection signal in the public record. This guide explains how to read the granted/revoked/reinstated timeline and how to spot the identity-flip pattern that drives modern double-brokering scams.
The out-of-service rate is the share of a carrier's inspections that put a vehicle or driver out of service. Learn how it's calculated, how to read it against the national average, and why it's a leading safety signal.
