Carrier monitoring: re-check carriers after you onboard them

A one-time vet is a photo, not a video. The day you approve a carrier, the record looks clean — but authority lapses, insurance drops below the amount your contract requires, safety ratings slip, and out-of-service rates climb in the weeks and months after you onboard. Carrier monitoring re-checks your saved carriers against FMCSA on a recurring basis and emails your team when something gets worse, so you find out from us instead of from a claim.

Check a carrier now

Run a free check now by MC or DOT number, then add the carrier to monitoring to keep watching it.

Just the number works — with or without the MC/DOT prefix, and spaces are fine. Tip: prefix an MC number with “MC” (e.g. MC123456) so it isn't read as a DOT number.

Why a one-time vet stops protecting you

Vetting at onboarding tells you the carrier was authorized, insured, and in good standing on that one day. Nothing about that day binds the carrier to stay that way. Operating authority gets revoked or goes inactive for failure to keep insurance on file. A liability policy gets cancelled and the new one comes in below the limit your contract demands — or never comes in at all. A clean safety record fills up with violations after a few bad inspections. None of this generates a phone call to you. It posts quietly to the carrier's FMCSA record, where it sits until someone looks again.

The carriers you book most are the ones most exposed to this drift, because you booked them once and stopped checking. Continuous carrier monitoring closes that gap by looking again, on a schedule, so the record you trusted at onboarding is the record you're still working from months later.

How CarrierClear monitoring works

Save a carrier to monitoring after you vet it, and CarrierClear re-pulls its public FMCSA record on a recurring basis. Each re-check is compared against the last one we have on file. When a tracked field changes for the worse, your team gets an email. When anything changes at all, it goes into the carrier's change-history log whether or not it triggered an alert.

  • Recurring re-checks. Saved carriers are re-pulled against FMCSA on a recurring basis — no manual re-lookups, no spreadsheet of MC numbers to babysit.
  • Alerts on worsening, not noise. You only get emailed when something deteriorates: authority goes inactive, insurance falls below required, safety slips, or out-of-service rates spike. A carrier that improves doesn't fill your inbox.
  • You pick the categories. Choose which kinds of change email your team. Want authority and insurance alerts but not every safety-rating tweak? Set it that way.
  • A change log that records everything. Regardless of your alert settings, the dated change-history log captures every change we see, so you have a full timeline to look back on.
  • Weekly watchlist digest. Team and Pro plans get a once-a-week roundup of your whole watchlist — what changed, what's holding steady — so re-vetting is a five-minute read instead of a fire drill.

What triggers an alert

Monitoring watches the four things that actually move your liability when they go the wrong direction. These are the same fields a one-time vet checks — the difference is that monitoring keeps checking them.

  • Authority goes inactive. Operating authority is revoked, suspended, or lapses. A carrier you approved as active can quietly lose the legal right to haul for hire — often because they let insurance fall off file.
  • Insurance below required. The liability/BIPD coverage on file drops below the federal or contract minimum, a policy cancels, or cargo coverage disappears. This is the gap that turns a routine load into an uninsured claim.
  • Safety change. A new unsatisfactory or conditional rating, or a meaningful shift in safety standing after fresh inspections and violations post to the record.
  • Out-of-service spike. The carrier's vehicle or driver out-of-service rate climbs relative to the national average — an early sign of a fleet that's degrading faster than its rating reflects.

Monitoring is an information signal, not a guarantee. We surface what changed in the public record and show you the reasons; the decision to keep or pause a carrier is yours.

Monitoring and broker liability

Negligent-selection exposure doesn't end at onboarding. If a carrier you kept using turns out to have lost its authority or dropped its insurance months earlier, "we vetted them when we signed them" is a thin answer. A dated change-history log shows you were watching the whole time the carrier was in your network — and shows exactly when a problem appeared, so you can act on it instead of discovering it in litigation.

This is the same liability theory at the center of broker negligent-selection cases. Ongoing monitoring with a timestamped record is how you keep a defensible vetting record current instead of frozen on the day you first approved the carrier.

Who needs continuous monitoring

  • Brokers with repeat carriers. If you book the same carriers week after week, those are the records most likely to have drifted since your last look — and the ones a single onboarding vet protects you from least.
  • Teams that can't re-pull by hand. Re-vetting a carrier list manually doesn't scale. Monitoring turns it into a passive process — alerts come to you, the digest summarizes the rest.
  • Anyone exposed to double-brokering drift. A carrier that flips to broker-only authority or quietly re-brokers your freight is a change you want to catch the day it shows up, not after a load goes missing.

Common questions

What is continuous carrier monitoring?
It's the practice of re-checking a carrier's FMCSA record on a recurring basis after you onboard them, instead of vetting once and assuming nothing changes. CarrierClear re-pulls each saved carrier, compares it to the last record on file, and emails your team when authority, insurance, safety, or out-of-service status gets worse.
How often does CarrierClear re-check my carriers?
Saved carriers on paid plans are re-pulled against FMCSA on a recurring basis as part of ongoing monitoring. Each re-check is compared against the prior record so you're alerted to changes, not just shown the current snapshot. Pro plans are processed first in the queue.
Can I choose which changes alert my team?
Yes. You pick which categories email you — authority, insurance, safety, out-of-service. The dated change-history log still records every change we detect regardless of your alert settings, so nothing is lost even if you've muted a category.
What's the difference between re-vetting and monitoring?
Re-vetting is the act of checking a carrier again; monitoring is doing it automatically and continuously so you don't have to remember. Monitoring re-checks your whole saved list on a schedule, alerts you only when something worsens, and keeps a timeline you can reference later.
Does monitoring guarantee a carrier is safe or legitimate?
No. CarrierClear is an information tool that surfaces changes in public FMCSA records and third-party screening. It does not certify a carrier's fitness, legitimacy, or insurance, and it is not legal advice or a consumer report. The decision to keep or drop a carrier stays with you.
Which plans include monitoring and the weekly digest?
Ongoing monitoring with email alerts and the change-history log is part of every paid plan (Solo $49, Team $99, Pro $199 per month). The team watchlist view and the weekly digest are Team and Pro; webhooks and the compliance CSV export are Pro.
