Carrier Vetting Checklist for Freight Brokers (2026)

Carrier vetting is no longer optional for freight brokers — it is a legal and operational necessity. In the era of nuclear verdicts, negligent entrustment claims, and increasingly sophisticated fraud, a broker that tenders a load to an unsafe or fraudulent carrier faces existential risk.

This checklist covers the 10 essential checks every freight broker should perform before tendering a load. For each check, we explain what to look for, why it matters, and how CarrierOk helps you get the answer quickly.

1. Verify Operating Authority

What to check: Confirm the carrier has active common carrier authority (or the specific authority type relevant to the service). Verify the MC number and DOT number match the entity you intend to work with.

Why it matters: Operating without valid authority is illegal. If a carrier hauls a load without authority, any resulting insurance claim may be denied, and the broker may be held liable for negligent selection.

How CarrierOk helps: Authority status is displayed prominently in every carrier profile, with full history including previous revocations. Set up monitoring for same-day alerts when authority status changes.

2. Confirm Insurance Coverage

What to check: Verify active BIPD (Bodily Injury & Property Damage) insurance meeting the minimum requirements for the cargo type. Check the insurer name, policy effective dates, and coverage amounts. For carriers hauling hazmat or specialized commodities, confirm the appropriate endorsements.

Why it matters: Insurance is the financial backstop if something goes wrong. A carrier with lapsed, insufficient, or fraudulent insurance documentation leaves the broker exposed. Minimum BIPD coverage is $750,000 for general freight, $1,000,000 for oil transport, and $5,000,000 for certain hazmat.

How CarrierOk helps: CarrierOk shows policy-level insurance data including insurer, coverage amounts, effective dates, and filing status. Monitoring alerts you when insurance lapses or changes.

3. Review BASIC Percentiles

What to check: Review the carrier's percentile scores across all 7 BASIC categories. Pay particular attention to Unsafe Driving, HOS Compliance, and Crash Indicator, as these correlate most strongly with accident risk.

Why it matters: BASIC percentiles are the most granular view of a carrier's safety performance. A carrier with high percentiles in critical categories is statistically more likely to be involved in a crash. In litigation, failure to check BASICs is increasingly cited as evidence of negligent carrier selection.

How CarrierOk helps: CarrierOk provides all 7 BASIC percentiles, including the two FMCSA hides from public view (Crash Indicator and Hazmat Compliance). Available via API and the platform UI.

4. Check the ISS Score

What to check: Review the carrier's ISS score for a composite view of overall safety risk. Use your organization's defined threshold to determine if manual review is required.

Why it matters: ISS synthesizes multiple safety dimensions into a single number, making it useful for quick triage and comparison. Carriers with ISS scores above 50 generally warrant closer examination.

How CarrierOk helps: ISS scores are included in every carrier profile and API response, alongside the underlying BASIC percentiles so you can see both the summary and the detail.

5. Run Chameleon Carrier Detection

What to check: Determine whether the carrier has any connections to previously shut-down, revoked, or out-of-service entities. Look for chameleon carrier signals including shared phone numbers, principals, and addresses.

Why it matters: Chameleon carriers appear clean on the surface but carry forward the same operational risk as the entity they replaced. They are a leading cause of preventable accidents involving carriers that passed standard vetting.

How CarrierOk helps: CarrierOk's chameleon detection system continuously analyzes connections across every FMCSA registrant. Chameleon signals appear automatically in carrier risk profiles with details about the linked entity.

6. Evaluate Fleet Size and Age

What to check: Review the carrier's number of power units and drivers as reported to FMCSA. Check how long the carrier has been in operation.

Why it matters: Very small fleets (1-3 power units) with very new authority may lack the operational maturity for certain loads. Fleet size also helps you assess capacity claims. A carrier claiming nationwide coverage with 2 trucks should raise questions.

How CarrierOk helps: Fleet size, driver count, and registration date are included in the carrier profile. The new entrant flag (under 18 months of operation) is surfaced in the risk signals array.

7. Review Out-of-Service (OOS) Rates

What to check: Review the carrier's driver OOS rate and vehicle OOS rate. Compare against the national averages (approximately 6% for driver OOS and 21% for vehicle OOS).

Why it matters: High OOS rates indicate systemic issues with driver compliance or vehicle maintenance. A carrier with a vehicle OOS rate significantly above the national average is not maintaining its equipment properly, which directly increases crash risk.

How CarrierOk helps: OOS rates are calculated from inspection data and displayed in the carrier profile alongside inspection counts and violation details.

8. Set Up Continuous Monitoring

What to check: Once a carrier passes your vetting process, add them to your monitoring panel so you receive alerts when their data changes.

Why it matters: Carrier risk is not static. A carrier that passed vetting six months ago may have since accumulated serious violations, lost insurance coverage, or had their authority revoked. Without monitoring, you will not know until something goes wrong.

How CarrierOk helps: CarrierOk monitoring provides same-day alerts for authority changes, insurance lapses, BASIC score changes, new chameleon signals, and other critical data changes. Alerts are delivered via email, in-platform notifications, or the monitoring API.

9. Verify Contact Information

What to check: Confirm the carrier's phone number, email, and physical address match what is on file with FMCSA. Be wary of carriers whose contact information does not match their registration data.

Why it matters: Mismatched contact information can be a sign of double-brokering fraud or identity theft. If the phone number on the rate confirmation does not match the phone number registered with FMCSA, proceed with extreme caution.

How CarrierOk helps: CarrierOk displays the FMCSA-registered phone numbers, mailing address, and physical address for every carrier. The Chrome Extension overlays this data directly in your browser when viewing load boards or carrier profiles in other systems.

10. Check New Entrant Flags

What to check: Determine whether the carrier is classified as a new entrant (registered with FMCSA for less than 18 months). If so, apply additional scrutiny to the other checks in this list.

Why it matters: New entrant carriers have limited inspection history, making traditional safety metrics less reliable. They are also statistically more likely to experience early authority revocation. Combined with chameleon detection, new entrant status helps identify carriers that may have re-registered to evade their safety history.

How CarrierOk helps: New entrant status is flagged in the risk signals array. Combined with chameleon detection and authority history, CarrierOk provides a complete picture of whether a new carrier is genuinely new or a re-registered high-risk operator.

Building a Scalable Vetting Process

Performing all 10 checks manually for every carrier is not practical for most brokerages. The key is to build a process that automates the data retrieval and applies your risk thresholds consistently.

With CarrierOk, all 10 checks are available in a single API call or a single platform lookup. The freight broker solution page explains how brokerages of all sizes use CarrierOk to standardize vetting, reduce risk, and onboard carriers faster.
