The short answer: yes. Brokers and shippers check your FMCSA file, usually through a vetting platform that pulls the free federal files from data.transportation.gov: Motus authority files posted daily by 9:30 AM Eastern, insurance and revocation files as 24-hour change logs, SMS results once a month. Since the Supreme Court decided Montgomery v. Caribe Transport II on May 14, 2026, they check it much harder. But they are almost never looking at a "CSA score" the way carriers imagine, because for property carriers the BASIC percentiles have not been public since the FAST Act of 2015. What an outsider actually sees is your authority status, whether minimum insurance is on file, your safety rating (Satisfactory, Conditional, Unsatisfactory or None) and raw counts of inspections, violations, crashes and out-of-service events. And here is the part nobody tells you: FMCSA itself asks people not to judge a carrier by this data. The market ignores that request. Both facts are true at the same time, and you have to work with both.
This page is about one thing only: how the outside world reads your file and what it costs you. If you want the underlying mechanics of BASICs, measures and percentiles, start with our CSA Scores Explained hub.
Most brokers never open the FMCSA website. They open a vetting platform that has already downloaded everything. That is possible because FMCSA gives the entire dataset away free under its Open Data Program on data.transportation.gov. There is no scraping and no back door: it is a published federal product, and the agency's own page states the posting times used in the table below.
| Public FMCSA data feed | What it contains | How often it refreshes |
|---|---|---|
| Company Census File | Every registered entity: name, address, power units, drivers, mileage, operation type, docket status | Daily, usually posted by noon Eastern |
| Motus Carrier and AuthHist files | Operating authority type and status, plus the timestamped history of every status change | Daily, posted by 9:30 AM Eastern |
| Motus Insur and InsHist files | Active and pending insurance policies, coverage limits, cancellations and replacements | Daily change log covering the last 24 hours |
| Motus RevokeSuspend file | Authorities suspended or revoked by the agency, with order and effective dates | Daily delta covering actions processed in the past 24 hours |
| Inspection and Crash Files | Roadside inspections, violation codes, out-of-service flags, crash reports (no driver personal data) | Daily, three years of inspection history published |
| SMS Input and Output files | The exact census, inspection, violation and crash records used for the month's SMS run, plus the computed results | Monthly snapshot taken the third or last Friday, results usually posted by the 15th of the next month |
Read that table again with a broker's eyes. Your insurance lapse is machine readable within about a day. So is a revocation order. So is the fact that your MC number was issued three weeks ago. The monthly SMS cycle only governs the safety measures, not the registration facts, which is why carriers are constantly surprised that "the broker knew before I did".
The monthly half of that table has a published clock, and you can read it off the SMS homepage at any time. This is how the cycle stood at the start of September 2026:
| SMS release cycle | What FMCSA published |
|---|---|
| Snapshot day | The third or last Friday of each month, when the census, inspection, violation and crash data are frozen for the run |
| Processing time | Usually 7 to 10 days of data sufficiency checks, validation and computation |
| Data current as of | July 31, 2026 |
| Website updated on | August 10, 2026 |
| Next update | Week of September 7, 2026 |
| Open data files posted | SMS input and output files usually by the 15th of the following month |
Practical consequence: a violation written at the roadside today does not move any BASIC until the next snapshot is taken and released, which is normally four to six weeks. A cancelled insurance filing moves your file tomorrow morning. Carriers routinely reverse those two in their heads and then chase the wrong problem.
An industry of monitoring platforms sits on top of the free files and sells alerts, scorecards and onboarding workflows: Carrier411, Highway, Truckstop RMIS, My Carrier Packets, SaferWatch and others, most of them wired directly into broker TMS software so a dispatcher never leaves the load screen. Carrier411 is the easiest one to check, because it publishes its own numbers: more than 3,000 freight brokers and shippers use it, including, by its own count, 97 of the top 100 brokers by net income; it monitors over 1.9 million companies, maintains 18 FMCSA data sets under subscription, and starts at $99 per month with a 30-day trial. It says it tracks all new applicants and every new MC number issued daily by FMCSA, which is how it catches carriers that reappear under a new docket. Its published feature list includes FMCSA authority and insurance, carrier safety ratings, BASIC percentile scores, inspections, violations, crashes, out-of-service information and census data.
Its FAQ also spells out the refresh cadence a broker actually works with: insurance and authority information is updated every weekday morning as FMCSA releases it, safety ratings are re-verified every weekend, out-of-service orders are checked daily, and SMS BASIC scores are loaded once a month in the first week. The same page describes "carrier qualification settings": each broker sets its own green, yellow or red rule on authority, insurance, safety rating and BASIC scores, and the platform applies that rule automatically at lookup. That feature is the mechanical reason there is no industry-wide CSA cutoff: the cutoff lives in each broker's settings.
And then the line that matters most to you: Carrier411 states plainly that it is not a service for trucking companies and does not allow accounts for trucking companies, dispatch services, authority services, compliance services, attorneys, consultants, staffing or outsourcing firms.
Three free federal sources, in the order a careful broker uses them.
| Information about your company | Visible to any broker (no login) | Visible only to you with a DOT PIN |
|---|---|---|
| Operating authority type and active status | Yes | Yes |
| Minimum insurance on file, carrier and policy details | Yes | Yes |
| Safety rating: Satisfactory, Conditional, Unsatisfactory or None | Yes | Yes |
| Inspections, violations and crashes with dates and codes | Yes | Yes |
| Out-of-service rates and fleet size | Yes | Yes |
| Measures for the public BASICs | Yes | Yes |
| BASIC percentile ranks and above-threshold flags | No on FMCSA's public page, hidden since the FAST Act of 2015 | Yes |
| Crash Indicator BASIC and Hazardous Materials Compliance BASIC | No, hidden from public view | Yes |
FMCSA states the rule directly on the SMS site: pursuant to the FAST Act of 2015, certain property-carrier information is no longer available for public display, public data includes inspection and crash data, investigation results and measures for all public BASICs, while the Crash Indicator and Hazardous Materials Compliance BASICs remain hidden. To see your own complete results you log in as the carrier. If you never claimed your record, our DOT PIN recovery guide covers that, and the exact intervention thresholds behind those hidden percentiles are broken down in what counts as a good CSA score.
This is the part the market quietly skips. Open the SMS homepage and the disclaimer is right there under the search box:
That language is not decorative, and it has two layers. FMCSA displays the paragraph above under the heading "FAST Act of 2015". A near-identical sentence reached the site earlier, through a 2011 settlement agreement (FMCSA press release of March 9, 2011) that ended a suit by three trucking associations over how CSA data was displayed. That settlement produced the second disclaimer still sitting next to it on the same page, the one about the prioritization symbol. Three further points from the agency's own material:
Federal law is equally thin on the broker's side. In a concurring opinion in the Supreme Court's May 2026 broker case, Justice Kavanaugh put it in one sentence, quoting the Seventh Circuit: the relevant regulatory agency, FMCSA, requires brokers to select a federally registered carrier but does not otherwise "impos[e] safety standards on broker hiring". At the FreightWaves Freight Fraud Symposium in Cleveland on May 20, 2026, six days after the decision, FMCSA deputy administrator Jesse Elison said in a keynote fireside chat: "we're not a certification agency", and the only time FMCSA makes a determination on a carrier's safety fitness "is when we say a company is unsatisfactory".
On May 14, 2026 the Supreme Court decided Montgomery v. Caribe Transport II, LLC, No. 24-1238, argued March 4, 2026, in a unanimous opinion by Justice Barrett, with a concurrence by Justice Kavanaugh joined by Justice Alito. The facts matter to you more than the law does.
Read the third bullet again. The number that put a broker in front of the Supreme Court was a safety rating, which is fully public, not a hidden BASIC percentile. That is the single most useful takeaway in this entire article for a small carrier.
Scale, from the Court's own opinion citing FMCSA statistics: roughly 28,000 brokers arrange about a third of all freight moved in the United States, using more than 780,000 carriers. Every one of those brokers just lost the preemption defense it had leaned on for years. Justice Kavanaugh added the practical consolation for the industry, leaning on what plaintiff's counsel conceded at oral argument: brokers should be able to successfully defend against these suits if they acted reasonably and arranged transportation with reputable trucking companies, and in counsel's words "the broker is not going to have a problem if it's asking the hard questions of the carrier".
Translated into your inbox: more questionnaires, more insurance certificate demands, more automated re-checks, and more brokers who simply set their platform rules tighter than the law requires.
In June 2026 the Transportation Intermediaries Association petitioned FMCSA for a federal motor carrier selection safety standard, arguing that brokers and shippers face an untenable burden inventing their own methodologies from "potentially suspect data". Its proposed test is deliberately minimal: a carrier is reasonable to use if it is registered under Title 49, meets minimum insurance requirements, and has not been determined unfit or ordered to discontinue operations. TIA warned in the same petition about "overcorrection across the industry, with increasingly restrictive carrier selection practices that exclude large numbers of otherwise compliant motor carriers", with a disproportionate effect on small carriers. The petition also states that more than 90 percent of motor carriers have no safety rating at all, and adds in a footnote that about 91.5 percent of registered carriers run ten trucks or fewer. TIA frames the gap as an old one: the modernized Safety Fitness Determination rule proposed in January 2016 was withdrawn in March 2017, the NAS review finished the same year, and the NPRM FMCSA had scheduled for June 2025 has not appeared.
The same petition has a second half that cuts the other way, and it is the half a small carrier should read first. Its full title is "Federal Motor Carrier Safety Selection Standard & Publication of High-Risk Carrier List", and in it TIA asks FMCSA to "immediately publish and maintain a list of motor carriers deemed to be 'high risk' by the FMCSA", to be incorporated by reference into the new standard. That is a public blacklist, drawn from the agency's own risk assessment, which is precisely the part of your file the public cannot see today. So the same document that warns about squeezing small carriers also asks the agency to publish a list they could land on. Read it yourself: it is public at regulations.gov, document FMCSA-2021-0054-0181, dated June 9, 2026 over the signature of TIA president and CEO Chris Burroughs, received by FMCSA the same day and posted to the docket on June 11, 2026. Per Overdrive's report of June 11, 2026, the list TIA has in mind would be built from percentile rankings above intervention thresholds in three or more BASICs, or in any one of Unsafe Driving, Crash Indicator, Hours-of-Service Compliance or Vehicle Maintenance. Nothing has been adopted: this is a petition for rulemaking, not a rule. A small-carrier group, the Small Business in Transportation Coalition, filed its own petition on June 23, 2026 challenging it, arguing that FMCSA should take a far more limited role and that any high-risk list be confined to carriers the agency has actually rated Unsatisfactory, because an unrated carrier is not an unsafe carrier, only one the agency has not gotten around to evaluating. In the coalition's words, "it appears TIA should be knocking on Congress' door, not the agency" (Trucking Dive, July 2, 2026).
From what carriers report and from how vetting platforms are built, the signals split into hard gates that a machine enforces and soft signals that a human weighs.
| Signal in your public file | Type | Typical effect on booking |
|---|---|---|
| Operating authority not active, or revoked | Hard gate | Automatic block. No human ever sees your name. |
| Minimum insurance not on file, or a cancellation posted | Hard gate | Automatic block, often the same day the filing changes. |
| Out-of-service order | Hard gate | Absolute stop, and correctly so. |
| Conditional or Unsatisfactory safety rating | Near-hard gate | Many brokers refuse outright after Montgomery. This is the litigated signal. |
| Vehicle or driver out-of-service rate far above the national average | Soft signal | Extra questions, sometimes a lower rate, sometimes a quiet no. |
| Recent crashes in the public record | Soft signal | Weighed without preventability context unless you supply it. |
| Cluster of violations in one BASIC area | Soft signal | Matters most where the cargo is sensitive. See what an hours-of-service violation is worth. |
| New MC number, tiny fleet, address matching a revoked carrier | Fraud filter | A common reason for rejection in 2026, and it has nothing to do with safety. |
| Stale MCS-150, wrong phone, mismatched address | Fraud filter | Reads as a chameleon or a double-brokering risk. Cheapest thing on this list to fix. |
Open any trucking forum and you will find the rule of thumb: "keep every BASIC under 65 and brokers will leave you alone". The number is real, but it is not a broker rule. It is FMCSA's own intervention threshold from the SMS methodology, the percentile at which the agency may prioritize a carrier for a warning letter or an investigation. For property carriers the threshold is 65 percent in three BASICs and 80 percent in the other four:
| BASIC | Intervention threshold, property carrier | What the public SMS page shows |
|---|---|---|
| Unsafe Driving | 65% | Measure only, no percentile |
| Hours-of-Service Compliance | 65% | Measure only, no percentile |
| Crash Indicator | 65% | Hidden entirely |
| Vehicle Maintenance | 80% | Measure only, no percentile |
| Controlled Substances and Alcohol | 80% | Measure only, no percentile |
| Driver Fitness | 80% | Measure only, no percentile |
| Hazardous Materials Compliance | 80% | Hidden entirely |
Two things follow. First, a broker cannot apply the 65 percent rule from FMCSA's public page at all, because the percentile is exactly the number the FAST Act took off it; what a platform shows a broker is a measure, a reconstruction from the raw monthly files, or a number the platform computed itself. Second, brokers copy 65 and 80 into their own qualification settings anyway, which is why the TIA petition asks FMCSA to publish precisely the list of carriers above those thresholds. Until that happens, the threshold is an enforcement trigger you can see only after logging in with your DOT PIN. The full breakdown by BASIC, with the passenger-carrier thresholds, is in what counts as a good CSA score.
Honest answer: FMCSA makes no such claim, and we will not invent one. The agency does not publish any declared link between SMS results and insurance pricing, and it explicitly asks readers not to use SMS data to judge a carrier's overall safety condition. What underwriters actually price on is their own loss data, your claims history, driver MVRs, equipment, radius and experience. Roadside inspection and crash history is public, so it is available to them, and many underwriters do look at it, but a specific promise like "one violation costs you X dollars in premium" is marketing, not fact. If someone quotes you a number, ask which carrier's rating manual it came from.

These are the questions as people actually type or prompt them. Each answer opens with the answer itself.
A broker does not see a BASIC percentile for a property carrier. Since the FAST Act of 2015, FMCSA keeps property-carrier percentiles and alert symbols off the public page and leaves measures, inspections, violations, crashes and out-of-service counts. Two BASICs, Crash Indicator and Hazardous Materials Compliance, are hidden from the public entirely. Commercial platforms sell their own products on top of the same federal files, and at least one of them advertises BASIC percentile scores as a feature.
Yes, and usually automatically. Most brokers never open the SMS website: their vetting platform has already downloaded the free federal files from data.transportation.gov. Motus operating-authority files refresh daily by 9:30 AM Eastern, insurance and revocation files are 24-hour change logs, and SMS results refresh once a month from a snapshot taken the third or last Friday. Registration facts reach a broker in about a day, safety numbers on a monthly clock.
There is no number, federal or industry-wide. FMCSA has never set a CSA cutoff for booking freight, and for property carriers the percentiles are not public in the first place. Each broker writes its own rule inside its own software, which is why one refuses you and another books you the same week. TIA petitioned FMCSA in June 2026 to create a uniform Motor Carrier Safety Selection Standard precisely because none exists today.
Loads, yes. Insurance, only indirectly. A Conditional safety rating is fully public on SAFER, and it is the one signal many brokers now treat as a near-automatic refusal: a Conditional rating is exactly the fact that put a broker in front of the Supreme Court in Montgomery v. Caribe Transport II. Underwriters price on their own loss data, claims history, driver MVRs and equipment, not on a rating, but the rating and the compliance review behind it are public and visible to them.
Yes, and it is the most consequential public fact about you. The safety rating (Satisfactory, Conditional, Unsatisfactory or None) sits on your SAFER Company Snapshot for anyone to read, no login needed. A Conditional rating is exactly the allegation that put C.H. Robinson in front of the Supreme Court in Montgomery v. Caribe Transport II, so many brokers now treat it as a near-automatic refusal. Most carriers have no rating at all: the TIA petition puts the figure above 90 percent, and "None" is not a negative mark, only an unrated carrier.
About one day. A cancellation posts to the Motus Insur daily change log on data.transportation.gov within 24 hours, and Motus authority files follow by 9:30 AM Eastern the next morning. Carrier411 says it loads insurance and authority updates every weekday morning as FMCSA releases them and alerts subscribers automatically. Practical rule: make sure the new filing posts before the old one cancels, then check li-public.fmcsa.dot.gov the next business day.
Usually a fraud filter, not a safety number. New MC number, a tiny fleet, an address or phone shared with a revoked carrier, or a stale MCS-150 reads on a vetting platform as a chameleon or double-brokering risk. Carrier411 states that it tracks every new applicant and every new MC number FMCSA issues each day for exactly that reason. Fix the census facts first: correct fleet size, working phone, matching address, current MCS-150.
No federal one. The 65 and 80 percent numbers people quote are FMCSA's intervention thresholds from the SMS methodology, the point where the agency may prioritize a carrier for enforcement, not a booking standard. Each broker writes its own rule into its platform settings, and for property carriers the percentile that rule needs is not even on FMCSA's public page. What every broker does check is binary: active authority, minimum insurance on file, no out-of-service order, no Unsatisfactory rating.
They do not affect your safety rating at all. The seven BASICs feed the Safety Measurement System, which FMCSA uses to prioritize enforcement interventions; a safety rating comes from a compliance review under 49 CFR Part 385 and is only Satisfactory, Conditional, Unsatisfactory or None. FMCSA states that a carrier can hold a Satisfactory rating and still exceed an intervention threshold in a BASIC. For the mechanics of all seven, see our CSA Scores Explained hub.

Yes. Brokers and shippers check your FMCSA file routinely, usually through a commercial monitoring platform rather than by visiting the SMS website. FMCSA publishes the underlying data free at data.transportation.gov: SMS results refresh monthly, while operating-authority files post daily by 9:30 AM Eastern and insurance files are 24-hour change logs. What brokers see for a property carrier is not a percentile score, it is your authority status, whether minimum insurance is on file, your safety rating if you have one, and your inspection, violation and crash history.
There is no federal number. FMCSA has never set a CSA cutoff for booking a load, and for property carriers the BASIC percentiles are not even public. Each broker writes its own internal rule inside its vetting platform, which is why one broker refuses you and the next one books you the same week. The Transportation Intermediaries Association petitioned FMCSA in June 2026 precisely because no uniform federal standard exists.
Not from FMCSA. Since the FAST Act of 2015, property carriers' BASIC percentiles and alert symbols are removed from public display, and the Crash Indicator and Hazardous Materials Compliance BASICs are hidden from public view entirely. The public page shows measures for the public BASICs plus counts of inspections, violations and crashes. Only you, logged in with your DOT PIN, and enforcement users see your complete results. Commercial platforms are a separate question: Carrier411, for example, lists FMCSA BASIC percentile scores among the features it sells to brokers, so do not treat "nobody can see it" as comfort.
No, the opposite. The SMS website carries FMCSA's own disclaimer: readers should not draw conclusions about a carrier's overall safety condition simply based on the data displayed in the system, and unless a carrier has an UNSATISFACTORY safety rating or has been ordered to discontinue operations, it is authorized to operate. Federal law requires a broker to use a federally registered carrier, but as Justice Kavanaugh noted in May 2026, FMCSA does not otherwise impose safety standards on broker hiring.
Because of Montgomery v. Caribe Transport II, LLC, No. 24-1238, argued March 4, 2026 and decided May 14, 2026. A unanimous Supreme Court held that the FAAAA does not preempt state-law negligent-hiring claims against freight brokers, since such claims fall within the statute's safety exception at 49 U.S.C. 14501(c)(2)(A). Brokers lost the preemption defense they had relied on, so a documented carrier-selection file became a legal necessity rather than a formality.
More often you are losing them because of a hard gate, not a score. Authority not active, minimum insurance not on file, a Conditional or Unsatisfactory safety rating, or an out-of-service order will stop you at onboarding automatically. Inspection, violation, crash and out-of-service numbers are read as soft signals by a human. Fix the binary items first: they are the ones that block you without anyone looking.
Within about a day. FMCSA's Motus insurance and revocation files on the DOT open data portal are daily change logs: policy cancellations and administrative suspensions or revocations processed in the past 24 hours appear there, and the Motus operating-authority files are posted daily by 9:30 AM Eastern. Monitoring services subscribe to those feeds and alert their broker customers automatically, which is why a broker often knows about a filing gap before you do.
You can reproduce almost all of it free: SAFER Company Snapshot at safer.fmcsa.dot.gov, Licensing and Insurance at li-public.fmcsa.dot.gov, and the SMS public page, plus your own full results after logging in with your DOT PIN. What you generally cannot buy is the commercial platform itself. Carrier411, for example, states plainly that it is not a service for trucking companies and does not allow accounts for trucking companies, dispatch services, authority services or compliance services.
