Most shippers vet a carrier once, when it joins the network, and then stop. The carrier they checked in January is not necessarily the carrier hauling their freight in October.
Carrier vetting is usually treated as an onboarding task. Authority is confirmed, insurance is on file, the safety record looks acceptable, and the carrier is approved. The file is closed, and the carrier moves into the rotation for months or years. In the meantime, the carrier’s authority, ownership, insurance, drivers, and safety data keep changing. The onboarding check captures a moment in time, not the current risk.
That gap is where a meaningful share of freight fraud operates. A carrier that passed a clean check can be sold, reinstated, reactivated, or taken over. A legitimate carrier can drift into an identity alert or a worsening safety profile without anyone on the shipper side noticing. Vetting that stops at onboarding does not see either change.
What Continuous Reverification Means
Continuous reverification or continuous carrier vetting, is the practice of re-checking carriers on an ongoing basis rather than once. It has three components, and each one covers a different failure point.
Verify the carrier. Confirm the company still holds the authority, insurance, and safety standing it held when you approved it. That means checking operating status, MC and USDOT identifiers, insurance filings, safety data, and any active alerts.
Verify the person. Confirm that the individuals operating the freight are who they claim to be, work for the carrier, and hold valid credentials. Drivers change. A carrier that was clean at onboarding can add a driver the next week, and that driver is part of the risk.
Revalidate changes. When something changes, re-run the relevant check. A new address, a new owner, a new driver, a new insurer, or a new alert should trigger a targeted review, not wait for the next annual cycle.
Authority Changes Happen After You Say Yes
Operating authority is not static. Carriers can change ownership, reinstate authority after a lapse, or be reactivated from dormant status. WTW’s 2025 analysis of motor carrier number manipulation describes recently activated or reinstated MC numbers with no operating history, and changes in ownership of MC numbers, as warning signs that call for investigation. A carrier that was legitimate at onboarding can be sold to a different operator, and the number you approved may now belong to a company you have never evaluated.
Enforcement actions create a second pattern. In one case reported by the DOT Office of Inspector General, a company owner allegedly tried to restart a shut-down business under a new USDOT number and authority, and falsely stated on the application that there was no relationship with other FMCSA-regulated entities. A carrier that appears clean on a new application may be the same operation that was shut down under a different name. That connection is visible only if someone reverifies ownership history, not just the current application.
Our own qualification procedure reflects this. The SOP requires a carrier to have at least 365 days of continuous authority, and it requires ownership attestation when the system requires it. Both checks are most useful when they are repeated, because a carrier’s authority record and ownership can change after the first review.
Identity Alerts Can Appear Later
A carrier with a clean identity record at onboarding can later acquire an identity alert. Highway’s identity alerts are designed to flag carriers whose identity may be fake, compromised, or misrepresented, and our procedure treats any active identity alert as a disqualifier unless a manager override is approved. The override path for identity theft itself requires live tracking, an explanation of what happened from verified contact details, verification that the person we are working with is actually associated with the company, and a conversation with the driver. None of those steps happen unless someone is watching for the alert in the first place.
The same logic applies to drivers. Our procedure requires that a carrier has never used an authorized user with a non-domiciled or limited-term government ID. That rule has to be applied to every new driver a carrier adds, not just the drivers present at onboarding.
Safety Scores Move, and Not Always Visibly
FMCSA’s Safety Measurement System updates monthly, using a rolling 24-month window of inspections and crashes. Recent violations are weighted more heavily than older ones, and carriers are compared against peers with similar numbers of safety events. A carrier can therefore move from acceptable to concerning without any single event that looks dramatic.
Two details matter for shippers. First, FMCSA removed SMS percentiles and alerts for property carriers from its public website under the FAST Act. Shippers therefore cannot simply look up a carrier’s percentile in a public tool, and access to the data depends on registration or on a platform that surfaces it. Second, FMCSA has been refining the methodology. A Federal Register notice in November 2024 described changes including consolidated violations, proportionate percentiles, and greater focus on recent violations. The practical implication is that the score you check today may be calculated differently next year, and the thresholds you rely on should be confirmed rather than assumed.
Data also lags. FMCSA notes that updates take roughly ten business days to process after each monthly snapshot, and registration changes may not appear until a later update. A carrier’s status can shift between checks, which is one more reason to set a monitoring cadence instead of relying on a single lookup.
What Triggers a Reverification
A practical program defines triggers in advance so that reviews happen because something changed, not because someone remembered. Reasonable triggers include:
- A change in operating authority status or ownership
- A lapse or pending cancellation on insurance
- A new identity alert
- Anew driver or equipment unit added to the carrier’s operation
- A move in the carrier’s safety percentile or the appearance of a new alert
- Any change on the DNU list.
Each trigger should have a defined check and an owner responsible for completing it.
Beyond triggers, a routine cadence catches what triggers miss. Monthly review of safety data for active carriers, and a full re-vet at a set interval, keeps the file current. For strategic carriers, this review belongs in the same meeting as the quarterly business review, so that performance data and risk data are discussed together.
What to Ask Your Provider
If your 3PL or managed transportation provider says carriers are vetted, ask when they were last re-verified, what triggers a review, and who owns the process. Ask how they track ownership and authority changes after onboarding, how they handle new drivers, and how they learn about identity alerts. Ask what happens when a carrier’s safety percentile moves in the wrong direction. A provider with a good answer will have a process, a cadence, and documentation. A provider without one is relying on the onboarding file, and that file gets older every month.
Continuous reverification is not a heavier burden than onboarding. It is the same checks, run on a schedule and in response to change. The carrier you approved is only as current as your last verification.
