Most carriers have no safety rating

Ask the federal record for a carrier's safety rating and the most likely answer, by far, is silence. Per FMCSA's own statistics, 93.7% of interstate freight carriers have no safety rating: 646,777 of 690,091 carriers as of the agency's 2021 data snapshot. Call it 94%.

Why almost nobody is rated

A safety rating (Satisfactory, Conditional, or Unsatisfactory) is issued only after a compliance review, on site or remote, and FMCSA reviews only a small share of carriers each year, with new authorities arriving constantly. Reviews go where the agency's prioritization sends them: crashes, complaints, intervention thresholds. The arithmetic never closes. The result: the rating field is empty for the overwhelming majority of carriers a broker will ever quote.

What "Not Rated" does and doesn't mean

Two opposite mistakes get made with unrated carriers, and both are expensive.

• Reading absence as clearance. "No negative rating on file" sounds like a pass. It isn't; it means FMCSA never looked. An unrated carrier can be carrying an inspection-failure rate triple the national average, and the rating field will never say so.
• Reading absence as disqualification. A broker who declines every unrated carrier has just declined roughly 94% of the interstate freight market, including most small fleets, most new entrants, and a large share of operators who simply never drew an audit.

The rating field, for most of the market, is not evidence in either direction. The evidence lives elsewhere.

The record that exists for every carrier

The same agency that can't audit everyone publishes operational data on everyone. For any carrier, rated or not, the public federal record carries:

• Roadside inspections: every inspection, with its violations and whether the vehicle or driver was placed out of service. fleetfax holds more than 9 million inspection records (October 2026).
• Out-of-service rates: the share of inspections that sidelined the truck or driver, comparable against FMCSA's published national averages, shown live on the out-of-service tracker.
• Crash records: about 5 million involvement records with severity (tow-away, injury, fatal).
• Authority and insurance history: grants, revocations, reinstatements, gaps, cancellation filings, churn.
• Registration data: fleet size, time since USDOT registration, addresses, officers, and the cross-carrier overlaps among them.

This is the data FMCSA's own prioritization runs on, and it is sufficient to build a meaningful safety read on the unrated majority: performance benchmarked against peer carriers, trends over time, and the identity patterns that ratings never captured anyway. The fleetfax carrier report shows every layer above, with the records behind it.

The post-Montgomery stakes

Since the Supreme Court ruled in Montgomery v. Caribe Transport II (May 14, 2026) that brokers can be sued for negligent carrier selection, the question "what did you check when you hired this carrier?" has legal weight for every U.S. freight broker. "The rating field was empty" describes 94% of the market; it isn't much of an answer. The underlying record is public, and it exists for every carrier, rated or not.
