How brokers vet carriers: what to check and why it matters more in 2026

Every load a freight broker covers starts with a carrier decision. Who is authorized to haul it, whether their insurance is current, whether their safety record holds up. These are questions that need answers before a load moves, not after something goes wrong.

This post covers what brokers check before booking a carrier, how to read the data they find, what credentials alone do not tell you, and what needs to be documented to protect the business.

What is carrier vetting

Carrier vetting is the process freight brokers use to verify a carrier’s identity, legal authority, insurance coverage, and carrier compliance history before tendering a load. At a minimum, it covers:

• Who the carrier is and whether their identity can be confirmed
• Whether they hold active, legitimate operating authority
• Whether their insurance meets coverage requirements and is current
• Whether their safety record reflects acceptable risk

Vetting is distinct from carrier sourcing or load matching. It sits at the front of a broader carrier management process, and how thoroughly a broker vets a carrier before booking shapes the risk profile of every load that carrier touches.

Why carrier vetting matters more in 2026

Carrier vetting is how brokers protect their business from legal exposure, cargo theft, reputational damage, and the financial consequences of a bad booking.

On May 14, 2026, the Supreme Court issued a unanimous decision in Montgomery v. Caribe Transport II, LLC that removed the federal preemption defense freight brokers had widely relied on to get negligent carrier selection cases dismissed early in the litigation. Though the ruling did not create a new duty or set a federal vetting standard, it did close brokers’ early exit from these cases.

Brokers will now defend more negligent selection claims through court process, and the decisions they make about which carriers to use will face a level of scrutiny many have not had to prepare for.

Strategic theft or cargo theft is a direct financial risk on every load. Cargo theft losses in the U.S. and Canada reached an estimated $725 million in 2025, a 60% increase from the prior year, with the average value per theft rising to nearly $274,000.

Organized criminal networks study freight flows, broker workflows, and verification processes to find exploitable gaps. Brokers who book without thorough vetting can unknowingly facilitate a well-planned theft operation.

What to check before you book a carrier

Carrier vetting looks different at every freight brokerage. Freight type, shipper requirements, and risk tolerance all factor into how a broker vets carriers. Though no single standard exists, these are the areas worth considering when building or refreshing a vetting process.

Authority status. Confirm active Motor Carrier operating authority through the FMCSA’s SAFER system. Active authority confirms the carrier is legally permitted to operate, but it does not confirm they have been operating long. Authority age matters: carriers with very recent authority have less verifiable history, and some fraud schemes specifically target newly registered or recently transferred MC numbers.

Operating history. Beyond authority age, look at how long the carrier has been actively operating under their current identity. A carrier with several years of consistent inspection history and stable ownership presents a different risk profile than one with frequent ownership changes or gaps in activity.

Insurance. Verify coverage type, limits, and effective dates directly with the issuing insurer, not from a certificate the carrier provides. Self-submitted certificates can reflect lapsed, altered, or outdated policies. Minimum requirements vary by cargo type and equipment, so confirming currency is as important as confirming existence. Carrier insurance monitoring after the initial check is worth building into the process as well.

Equipment verification. Confirm that the carrier’s DOT number, equipment type, and vehicle identification align with what they represent themselves to be operating. Mismatches between listed equipment and what shows up at a shipper are a signal worth catching before a load is tendered.

CSA BASIC scores. CSA BASIC scores give brokers a window into a carrier’s compliance history. The Safety Measurement System (SMS) that generates them is an enforcement prioritization tool, not a safety rating, which is worth keeping in mind when interpreting results.

SMS scores carriers across seven behavior categories known as BASICs: unsafe driving, hours-of-service compliance, driver fitness, controlled substances and alcohol, vehicle maintenance, hazardous materials compliance, and crash indicator. Scores run from 0 to 100 relative to peer carriers; higher scores indicate more frequent or more serious violations.

Note that under the FAST Act of 2015, the Crash Indicator and Hazardous Materials Compliance BASICs are not publicly visible for property carriers. Brokers can access the remaining categories through the FMCSA SMS website

Out-of-service rates. Separate from CSA scores, out-of-service rates reflect the percentage of inspections that resulted in a vehicle or driver being placed out of service. High out-of-service rates indicate maintenance or compliance issues that may not be fully captured in BASIC scores alone.

Safety rating. The FMCSA assigns a formal safety rating after a compliance review, an onsite investigation of a carrier’s operations covering drivers, vehicles, hours of service, maintenance records, and safety management controls. The result is one of three ratings: satisfactory, conditional, or unsatisfactory.

Two limitations are worth understanding. Compliance reviews are not conducted on all carriers. Approximately 92% of active interstate motor carriers have no safety rating at all, so an unrated carrier is not automatically a concern.

A satisfactory rating also reflects compliance at the time of the last review, not current performance. Safety ratings cannot be updated by on-road data alone, meaning a carrier’s rating can remain satisfactory even as their CSA scores worsen.

Identity and contact verification. Confirm that the carrier’s listed physical address corresponds to a real business location, that their phone number routes to someone who can identify the company by name, and that the person tendering the load matches the carrier of record. These checks are basic but often skipped under time pressure, and they are among the first signals that surface in identity-based fraud.

Third-party performance scores. FMCSA data reflects regulatory compliance. Third-party scoring systems layer in operational reliability: on-time performance, service consistency, customer complaint history, and delivery patterns. These scores surface carriers who are technically compliant but operationally inconsistent, a distinction that FMCSA data alone does not capture.

Complaint and watchdog records. The Transportation Intermediaries Association’s Watchdog database aggregates complaints filed by TIA members against specific carriers and brokers. Because reports come from brokers actively working the market, patterns appear here before they show up in regulatory data. A carrier with multiple unresolved complaints warrants scrutiny even if their FMCSA record looks clean.

Documentation is an important part of the vetting process

Post Montgomery, brokers can expect to defend more negligent hiring claims that reach the litigation stage. Documentation evidencing reasonable care in the carrier selection process will be critical to their defense.

Understanding the distinction between carrier qualification and carrier selection matters here. Qualification is the process of determining whether a carrier meets a brokerage’s baseline standards before they are added to an approved network. Selection is the decision to use a specific carrier for a specific load.

Both can be scrutinized in a negligent hiring claim, and both require their own documentation. A carrier who passed qualification checks at onboarding does not automatically have a documented selection decision for every load they cover.

In a negligent-selection case, the fight is rarely about whether you checked authority and insurance. The question is whether you weighed the safety signals a reasonable broker would have looked at, and whether you can prove it. That is the gap plaintiff attorneys target: the space between “we ran a check” and “here is the record of what we saw and what we decided.”

The “knew or should have known” standard turns on the information available to you at the time of carrier selection. A carrier’s crash history, out-of-service rates, and BASIC scores all live in public FMCSA data.

A contemporaneous record, meaning one created at the time of the decision rather than reconstructed from memory later, is what separates a defensible decision from an indefensible one. Defensible documentation means:

• A written standard operating procedure (SOP) that defines who runs vetting checks, how, and when, applied consistently across the team, not carrier by carrier or employee by employee.
• Timestamped records of what was checked, from what source, and when
• Documentation of how exceptions were handled and why. Exception management is a specific area of scrutiny in litigation, because inconsistency in how exceptions are treated signals an absence of process.
• Evidence that carrier was monitored after onboarding

As industry vetting norms develop in response to Montgomery, what qualifies as reasonable will move with them. Many brokers are already running sophisticated checks, inspection history, crash trends, ongoing monitoring, and documented exceptions. That practice is setting the baseline.

The decisions made during carrier selection and onboarding are the foundation of that record. What gets documented at that stage is what a broker can point to later.

How Carrier Hub improves carrier vetting and compliance monitoring

Running a thorough vetting process across multiple tools, tabs, and manual calls is time-consuming. Carrier Hub is Truckstop’s carrier vetting and compliance monitoring tool built for freight brokers who need to check carriers quickly, consistently, and with documentation to support their process.

Carrier Hub consolidates the core vetting checks into one place. Authority status, insurance, safety ratings, CSA scores, and complaint history are accessible from a single workflow, so a broker can run a complete check without switching between the FMCSA’s SAFER system, a separate insurance verification tool, and a watchdog database.

Beyond the pre-booking check, Carrier Hub Advanced monitors a broker’s active carrier network for changes after the initial vetting. When a carrier’s insurance lapses, their authority is revoked, or their safety profile changes, the system flags it automatically rather than waiting for the broker to notice during the next check.

For brokers building or refreshing their carrier vetting process, Carrier Hub removes the friction from doing it consistently.

Run carrier decisions in one place

Carrier vetting is not a single check. It is a process that covers identity, authority, insurance, safety history, and ongoing status, and it needs to happen consistently, on every carrier, with documentation that holds up when it matters.

The brokers who do it well are not necessarily running more checks than everyone else. They are running the same checks every time, reading the results with judgment, and keeping a record that reflects what they saw and what they decided. That consistency is what builds a defensible process, protects shipper relationships, and reduces the risk that comes with every load they cover.

Carrier Hub is built for brokers who want to run that process without the friction of managing it across multiple tools.
