What carrier vetting actually is
Carrier vetting is the workflow a freight broker uses to confirm a motor carrier is qualified to haul a specific load before tendering it. The workflow has been part of broker operations for decades; what has changed is what the workflow is for.
Before May 14, 2026, vetting was primarily an operational risk-management practice. Brokers checked safety ratings and insurance certificates because the alternative was paying cargo claims and dealing with carrier defaults. After the Supreme Court's unanimous decision in Montgomery v. Caribe Transport II, vetting is also the broker's primary litigation defense against negligent-hiring claims that now proceed in state courts across the country.
The technical work of vetting did not change. The framing did. That framing changes which artifacts matter and how they have to be captured, locked, and retained.
Why vetting matters now in a way it didn't before
The legal landscape shifted in one day. For decades, the Federal Aviation Administration Authorization Act of 1994 (FAAAA) preempted state-law negligent-hiring claims against brokers in most circuits. Brokers had a federal-preemption defense that knocked out most claims at the pleading stage. Vetting was good practice but not the primary defense.
Montgomery v. Caribe Transport II changed that. The Supreme Court held unanimously that the FAAAA does not preempt state-law negligent-hiring claims against brokers, because such claims fall within the statute's safety-regulation exception. The cases now proceed in state court, on the merits.
The merits turn on what the broker actually checked and what the broker can prove they checked. The first question is operational. The second is documentary. Brokers who can produce a contemporaneous, tamper-proof record of FMCSA safety rating, CSA scores, insurance currency, and operating authority at the moment of booking are in a fundamentally different legal category than brokers who cannot.
The four-check framework
A defensible carrier vetting process boils down to four checks, captured at booking, locked, and retained. The four are not arbitrary; they map to the negligent-hiring elements a plaintiff's lawyer will press in discovery.
1. FMCSA safety rating
Every motor carrier with active operating authority has one of four FMCSA safety ratings: Satisfactory, Conditional, Unsatisfactory, or Not Rated. The rating reflects the carrier's last compliance review and is publicly available on FMCSA SAFER. A Conditional rating is a documented flag; an Unsatisfactory rating means the carrier is prohibited from operating; Not Rated is common for newer carriers and is not disqualifying by itself.
2. CSA scores
The Compliance, Safety, Accountability program tracks carrier performance across seven BASIC categories on a percentile scale. Five BASICs are publicly displayed on FMCSA SMS. The two that matter most for broker negligent-hiring exposure are Unsafe Driving and Hours of Service Compliance. Alert status (above the 65th percentile, or 60th for hazmat and passenger) is a documented flag the broker has to address before booking.
3. Insurance currency and limits
FMCSA requires motor carriers of general property freight to maintain $750,000 in primary auto liability. Many shippers require $1M or more. Insurance lapses happen; the carrier listed as authorized in SAFER may be three weeks past their policy cancellation date. The vetting standard is to obtain a current certificate of insurance from the carrier's agent directly, confirm coverage matches the load requirements, and capture the certificate at the moment of booking.
4. Operating authority status
Operating authority is the legal permission to haul. A carrier suspended, revoked, or never granted appropriate authority for the load type is indefensible to book. Authority status changes quickly; the SAFER record at the moment of booking is the artifact that matters, not the record at the moment a discovery request arrives.
What gets captured
For each load, the vetting record should include a tamper-proof snapshot of each of the four checks as they stood at booking, with a system-generated timestamp. Specifically:
- SAFER snapshot showing safety rating and authority status
- SMS snapshot showing CSA percentile scores across publicly displayed BASICs
- Certificate of insurance with policy numbers, limits, dates, and any required endorsements
- Broker-carrier agreement reference
- Rate confirmation with MC number matching authority record
- Rationale notes for any alert-status BASIC or other flag the broker booked through
- System-generated capture timestamp
The PDF + JSON evidence pack VettedHaul exports on demand is structured exactly around this record. Defense counsel intakes the packet, validates the chain of custody, and uses it to frame the early settlement conversation.
Carrier-type addenda
The four core checks apply to every carrier and every load. Some carrier and load types add specific checks on top:
- Owner-operators: identity-verification checks (phone, address, EIN match), 18-month operating threshold, leased-on vs own-authority confirmation, driver ID at pickup.
- Established fleets: written safety program request, multi-authority confirmation, peer-cohort CSA trend analysis.
- Hazmat loads: hazmat authority verification, Hazardous Materials Compliance BASIC review, driver hazmat endorsement confirmation, higher insurance limits (60th percentile CSA threshold applies).
- Refrigerated loads: reefer equipment specs and maintenance, reefer-breakdown insurance endorsement, temperature-recording capability, food-safety compliance.
The documentation problem most brokers have
Most small and mid-size brokers run carrier vetting through some combination of FMCSA SAFER lookups, screenshots saved to a folder, a spreadsheet, and the institutional memory of whoever booked the load. Three reasons this does not survive a deposition.
First, none of those tools timestamp and lock the record at the moment of booking. A spreadsheet row can be edited at any time. A folder of PDFs lacks chain-of-custody metadata.
Second, FMCSA data ages out monthly. Pulling SAFER data now and showing it to a jury proves nothing about what the broker saw a year ago when the load was booked.
Third, vetting is not a one-shot event. The carrier booked clean in January may be in CSA alert by June. Without continuous monitoring and logged broker responses to alerts, the record has gaps that a plaintiff's lawyer fills with implication.
What a tamper-proof record looks like
Three properties define a defensible record-keeping system:
- Timestamped at capture. The timestamp comes from the system, not from a user-entered date field.
- Immutable after capture. The record cannot be edited or deleted after the fact except through an audited process that logs the change.
- Access-logged. Every view of the record is logged with user, time, and source. Defense counsel uses the access log to establish chain of custody.
VettedHaul implements all three by default. Spreadsheets fail all three. Folder-of-PDFs systems pass the first but fail the second and third.
Monitoring and re-vetting cadence
Initial vetting at booking is necessary but not sufficient. Carriers change. Insurance lapses. CSA scores drift. Authority gets suspended. The continuous-monitoring layer surfaces these changes and logs the broker's response.
Practical cadence:
- Weekly automated check against FMCSA + insurance + authority for all active carriers
- Immediate broker review on any alert-state change
- Quarterly comprehensive review for high-frequency carriers
- Annual carrier-packet refresh (W-9, insurance certificate, signed agreement)
The audit trail of monitoring alerts plus broker responses is itself a defensive artifact. A broker who keeps booking a carrier after their CSA goes into alert without a documented response is the discovery exhibit a plaintiff's lawyer builds a case around.
How to get started today
For brokers without a defensible vetting process in place, the practical steps in order:
- Write a one-page carrier vetting process document describing the four core checks, capture method, retention period, and re-vetting cadence.
- Set up the capture tool. VettedHaul is purpose-built for this. A free folder-of-PDFs system is the bare minimum starting point.
- Apply the process to every new booking starting day one. Do not backfill historical loads; forward-looking documentation is what counts in the post-Montgomery world.
- Turn on continuous monitoring for all active carriers.
- Hand your one-page process document to your insurance underwriter at next renewal. Contingent auto carriers are asking for this; the document supports better rates.
The bottom line
Carrier vetting is the same workflow it has always been. The legal stakes are not. Post Montgomery v. Caribe Transport, every broker needs a defensible per-load record that demonstrates reasonable care at the moment of booking. The four-check standard, captured in tamper-proof form, retained per a documented policy, monitored continuously, is the working definition of defensible.
