Carrier Vetting Checklist: What Dispatchers Check
Dispatcher-side carrier vetting verifies active MC/DOT authority, current MCS-150 and safety rating, insurance confirmed directly with the issuing agent plus FMCSA filings on record, and SAFER safety data including out-of-service rates and crash history. Instant disqualifiers: inactive authority, no insurance filing, Unsatisfactory rating, double-brokering evidence. Document the decision in a carrier file and re-vet on schedule — insurance at renewal, safety data quarterly, full re-vetting annually.
When you dispatch for owner-operators — or when you broker a load to another carrier — the carrier's problems become your problems. An inactive authority, a lapsed insurance filing, a Conditional safety rating: any of them can strand your freight, kill your broker relationship, or put an unqualified truck on the road under your name.
Vetting is the dispatcher's due diligence, performed before the first load and repeated on a schedule after. This is the dispatcher-side checklist — distinct from the shipper's carrier selection process, which answers a different question for a different audience.
Authority and Operating Status
Start with the fundamentals: verify the MC number is active and the operating authority matches the freight — interstate authority for interstate loads, and the right authority type for the operation. Check the USDOT number status alongside it. An 'active' MC with an inactive DOT, or authority that does not cover the movement, is a disqualifier, not a technicality.
Confirm the carrier's MCS-150 is current and the safety rating: Satisfactory is the standard most brokers and shippers require; Conditional demands a hard look at why; Unsatisfactory is an automatic pass. Check for recent enforcement actions, revocations, or reinstatement history — a carrier that lost authority last year and got it back last month deserves scrutiny, not trust.
Run these checks through FMCSA's official carrier search (safer.fmcsa.dot.gov) and the FMCSA QCMobile app — primary sources, not the carrier's screenshots. Our MC number lookup guide walks through reading the results.
Insurance Certificates and Filings
Request the certificate of insurance directly from the carrier's insurance agent or broker — not just from the carrier. Certificates are easy to forge and easy to let lapse; verifying with the issuing agent takes one phone call and eliminates the most common fraud vector in carrier vetting.
Verify the filings match the operation: BMC-91 or BMC-91X on file with FMCSA for the required auto liability, and cargo insurance at the limits your freight requires — confirmed by certificate, not by assertion. Check effective dates: a certificate showing coverage that expired last week is a carrier operating uninsured, whatever they tell you.
Match the policy to the freight: reefer freight needs the refrigeration breakdown endorsement, hazmat needs the right liability limits and MCS-90, high-value freight needs adequate cargo limits. A carrier insured for $100,000 in cargo on your $400,000 load is not vetted — our certificate of insurance guide explains what to read on the cert.
SAFER Data and Safety History
Read the carrier's safety data like an underwriter: inspection history, out-of-service rates for vehicle and driver, crash history, and CSA percentile picture across the BASICs. You are looking for patterns, not perfection — a small carrier with a few inspections and no OOS orders reads differently from one with a 30% vehicle out-of-service rate.
Pay special attention to the Unsafe Driving and Vehicle Maintenance BASICs, which predict future roadside trouble, and to crash indicators. A carrier whose trucks keep getting placed out of service will strand your freight at a scale house — and the broker will remember who dispatched the truck, not just who owned it.
Set your thresholds in writing before you need them: minimum time in business, maximum OOS rates, no Conditional ratings without review, no unresolved enforcement actions. Written standards make vetting consistent and defensible — 'we always check' beats 'we usually check' when something goes wrong.
Red Flags That Disqualify
Certain findings end the conversation: inactive or revoked authority, no insurance filing on record, an Unsatisfactory safety rating, or evidence of double-brokering history. These are not 'monitor closely' situations — they are disqualifications. Put the truck down and find another carrier.
Serious warning signs demand investigation before any load: very new authority with no inspection history (not disqualifying alone, but price the risk), frequent authority revocations and reinstatements, a Conditional rating, mismatch between the carrier's listed equipment and what shows up, and reluctance to provide the insurance agent's contact. Any one of these can be innocent; two together rarely are.
Watch for identity games: MC numbers that recently changed names, carriers operating from the same address and phone as a revoked carrier, and principals with histories at failed carriers. FMCSA's chameleon-carrier enforcement exists because the pattern is real — our double-brokering protection guide covers the fraud indicators in detail.
The Vetting File and Re-Vetting Schedule
Document every vetting decision in a carrier file: the date, what you checked, what you found, and who approved the carrier. When a vetted carrier has a problem later, the file proves your due diligence — and when a broker asks why you used a carrier, the file is the answer. No file, no proof.
Vetting is not one-and-done. Re-verify on a schedule: insurance certificates at every renewal, authority and safety data quarterly, and full re-vetting annually or after any incident. Carriers' situations change — insurance lapses, ratings change, ownership turns over — and the carrier you vetted in January may not be the carrier operating in October.
Automate what you can: carrier-monitoring services that alert you to authority, insurance, and safety-status changes turn re-vetting from a quarterly project into a background process. The dispatcher who learns about a lapsed filing from an alert beats the one who learns about it from a broker's angry phone call.
Vetting as a Dispatch Service Standard
If you hire a dispatch service, ask how they vet the carriers they work with — including you. A dispatcher who runs your authority, verifies your insurance, checks your safety data, and keeps a file is protecting your operation and theirs. A dispatcher who will dispatch anyone with a pulse is a liability you are paying for.
At JackRick Logistics, every carrier we dispatch for goes through qualification: authority verified, insurance confirmed with the agent, safety data reviewed, and the file kept current. It is part of the flat 10% per load service — invoiced Fridays, no retainer, no minimum, no long-term contract, 30 days' notice to walk away.
Vetting protects the freight, the broker relationship, and the carrier's own authority. It is unglamorous work that prevents the exact disasters — stranded loads, uninsured losses, enforcement actions — that end small carriers. Do it before the first load, and keep doing it.
Key takeaways
- Verify authority, safety rating, and insurance with primary sources — not screenshots.
- Confirm insurance with the issuing agent; certificates alone are forgeable.
- Read SAFER data like an underwriter: OOS rates and crash patterns predict trouble.
- Set written vetting thresholds before you need them.
- Document every vetting decision; re-vet on a schedule, not on memory.
- Instant disqualifiers: inactive authority, no filing, Unsatisfactory rating, double-brokering.
Questions carriers ask
What should a dispatcher check before using a carrier?
Active MC and DOT authority matching the freight, current MCS-150, safety rating, insurance verified with the issuing agent (not just the carrier), FMCSA filings on record, and SAFER safety data including out-of-service rates and crash history.
How do I verify a carrier's insurance is real?
Get the certificate of insurance and confirm it with the issuing insurance agent directly — one phone call eliminates the most common fraud vector. Then verify the FMCSA filings (BMC-91/91X) are on record and current.
What safety rating should I require?
Satisfactory is the standard most brokers and shippers require. Conditional demands investigation into why; Unsatisfactory is an automatic disqualification.
What are instant disqualifiers in carrier vetting?
Inactive or revoked authority, no insurance filing on record, Unsatisfactory safety rating, and evidence of double-brokering. These end the conversation — find another carrier.
How often should carriers be re-vetted?
Insurance at every renewal, authority and safety data quarterly, full re-vetting annually or after any incident. Consider a monitoring service that alerts you to status changes automatically.
Is dispatcher vetting the same as shipper vetting?
No — this checklist is the dispatcher-side qualification of carriers before dispatching them. Shipper-side carrier selection answers a different question; see our guide on how shippers vet carriers.
