How to Vet a Miami Carrier: FMCSA Safety Scores, Authority and Insurance (2026)

Before you tender a load to a Miami trucking company, three checks take about ten minutes and prevent most of the problems that end in a cargo claim: is the operating authority active, is the insurance real and adequate, and what does the carrier’s FMCSA safety data actually say. Price is the last question, not the first.

Check the authority first

Start at FMCSA’s SAFER Company Snapshot. You want the carrier’s USDOT number, an active operating status, and if they are moving freight for hire across state lines, an active MC docket. A “not authorized” or “out of service” status is the end of the conversation.

Also confirm what the company actually is. A broker is not a carrier, and a dispatcher is neither — our explainer on the difference between a freight broker and a dispatcher matters here, as does our guide to broker authority and the surety bond if the party you are dealing with is brokering your freight.

Understand what the safety data is, and is not

FMCSA’s Safety Measurement System scores carriers by comparing them against peers with similar inspection volume. Scores are expressed as percentiles, where higher is worse. The categories have historically been the BASICs: Unsafe Driving, Crash Indicator, Hours-of-Service Compliance, Vehicle Maintenance, Controlled Substances and Alcohol, Hazardous Materials Compliance, and Driver Fitness.

Two caveats matter for anyone using these numbers commercially:

• Not everything is public. Crash Indicator and Hazardous Materials Compliance percentiles are not displayed publicly for property carriers.
• The methodology has been changing. FMCSA proposed a revised measurement system in a 2023 Federal Register notice — consolidating violation codes into groups, simplifying severity weighting and renaming the BASICs as compliance categories. Check the FMCSA site for how scores are currently presented rather than relying on a number you saved last year.

An SMS percentile is also not a safety rating. A safety rating of Satisfactory, Conditional or Unsatisfactory comes from a compliance review. Many perfectly good carriers are simply “unrated” because they have never had one.

Read the scores like an operator

A single high percentile on a low-inspection carrier means little. Look for pattern and context:

• Vehicle Maintenance running high usually shows up later as a breakdown on your load.
• Hours-of-Service problems predict missed appointments and, in South Florida traffic, real schedule risk. Our guide to hours of service and ELD rules in Miami delivery windows explains why.
• Unsafe Driving is the category most correlated with crash risk, and the one your insurer will ask about.
• Inspection volume matters. Ten inspections is not a trend.

Verify the insurance, do not assume it

Federal minimum financial responsibility for general freight is $750,000. Certain hazardous materials require $1 million or $5 million. That is the federal floor, not a cargo policy — motor truck cargo coverage is separate, and the limit is often far lower than the value of a full container of electronics or pharmaceuticals.

Ask for a certificate of insurance issued directly by the agent, with your company named as certificate holder. Confirm the cargo limit, the deductible, and any exclusions for theft, unattended vehicles or specific commodities. Our piece on cargo insurance vs. carrier liability explains why carrier liability alone rarely makes you whole.

South Florida specifics

Miami’s carrier market is deep and fragmented, which is good for capacity and bad for vetting discipline. Two local risks deserve extra attention: double-brokering, where the carrier you vetted is not the carrier that shows up, and cargo theft, which concentrates around high-value lanes and unsecured drop yards. Our Florida cargo theft prevention guide covers practical controls. For port work specifically, add the checks in how to choose a drayage carrier at PortMiami.

Working with an asset-based 3PL removes a layer of this risk, because the equipment and the drivers belong to the company you contracted with.

Frequently asked questions

What is a good FMCSA BASIC score?

Scores are percentiles where higher is worse, so lower is better. Rather than chasing a single number, look at whether any category is near or above the intervention threshold, how many inspections the score is based on, and whether the pattern is improving or worsening.

Are all FMCSA safety scores public?

No. For property carriers, the Crash Indicator and Hazardous Materials Compliance percentiles are not displayed publicly. The remaining categories, along with inspection and crash data, are available through FMCSA’s public systems.

How much insurance is a trucking company required to carry?

The federal minimum for general freight is $750,000 in financial responsibility, with $1 million or $5 million required for certain hazardous materials. Motor truck cargo insurance is separate and its limits are set by the carrier’s own policy.
