How to read FMCSA safety records after a truck crash: safety ratings, SMS data, inspections, crash history, insurance filings and chameleon carriers.
Reviewed by Larry Forman, Attorney
After a crash with a commercial truck, one of the first questions is what kind of company put that truck on the road. A trucking company's FMCSA safety records are public, at least in part, and they can show a pattern long before anyone files a lawsuit: failed inspections, out-of-service orders, earlier crashes, or a federal rating that says the company's safety controls weren't working.
This guide explains what's in those records, how to look a carrier up, what the public can't see, and how the information is used in a Kentucky truck accident case.
Interstate trucking companies, and many intrastate carriers, are registered with the Federal Motor Carrier Safety Administration (FMCSA) and assigned a USDOT number. It's usually painted on the side of the tractor and printed on the police crash report. Once you have it, you can search three free federal tools:
If you don't have the USDOT number, the company name and city usually work in SAFER. The truck's trailer may belong to a different company, so check every name on the crash report.
FMCSA assigns a rating only after an investigation of the company. There are three ratings, plus "unrated" (49 CFR 385.3):
| Rating | What federal rules say it means |
|---|---|
| Satisfactory | The carrier has "adequate safety management controls" in place and functioning |
| Conditional | The carrier doesn't have adequate controls, which "could result in" violations of the safety fitness standard |
| Unsatisfactory | The carrier doesn't have adequate controls, which "has resulted in" those violations |
| Unrated | FMCSA hasn't assigned a rating |
Most carriers are unrated, because FMCSA doesn't investigate every company. An unrated carrier isn't necessarily safe or unsafe. A conditional rating is a warning sign. An unsatisfactory rating is more serious: once it becomes final, the carrier "is prohibited from operating a CMV" (49 CFR 385.13). A company still running trucks after that point is breaking federal law.
Every roadside inspection is logged, along with each violation found: brakes, tires, lights, cargo securement, driver licensing, medical certification, hours of service and more. Some violations are serious enough that the truck or driver is placed out of service on the spot. A carrier whose out-of-service rate runs well above the national average is showing a pattern, not a one-time mistake.
SAFER and SMS list reportable crashes involving the carrier's trucks over the past two years. A crash record by itself doesn't mean the carrier was at fault. FMCSA runs a program that lets carriers ask for a review of certain crashes, and crashes found "not preventable" are listed separately and left out of the crash measure.
Some of the most useful scores are hidden. Under the 2015 FAST Act, FMCSA removed property carriers' SMS percentiles and alerts from public view. The public can still see inspection, crash and investigation data and "measures" for most categories, but not the Crash Indicator or Hazardous Materials categories. Passenger carriers' percentiles, including bus companies, remain public. That matters in bus wreck cases.
FMCSA also posts this caution on the SMS site: "Readers should not draw conclusions about a carrier's overall safety condition simply based on the data displayed in this system." Its symbols aren't a safety rating. FMCSA has approved a revised SMS methodology that regroups the categories, but as of October 2026 the current system is still in use.
In a lawsuit, much of what's hidden can be obtained through discovery: the company's own FMCSA correspondence, investigation reports, warning letters, internal safety audits and the driver-level records the company is required to keep.
Some companies with bad records shut down and reopen under a new name and a new USDOT number, with the same owners, trucks and drivers. These are called chameleon or "reincarnated" carriers. Federal rules prohibit two or more carriers from using "common ownership, common management, common control, or common familial relationship" to avoid compliance or hide a history of non-compliance (49 CFR 385.1005).
Signs of a chameleon carrier include:
When a chameleon carrier is involved, the predecessor company, its owners and its insurer may also be part of the case.
FMCSA records rarely prove what caused a particular crash on their own. They matter because they show what the company knew, or should have known, before the crash.
SMS data is updated monthly and generally covers a rolling two-year window. Inspections age off. Ratings change. A carrier can file new insurance or a new name. Download and save the SAFER snapshot, the SMS pages and the Licensing and Insurance history as soon as possible after the crash, with the date you viewed them. Then send a preservation demand for the company's own records, as explained in our black box evidence guide.
We pull and preserve the public FMCSA history in the first days of a case, then go after what the public can't see: investigation files, driver qualification files, maintenance records and dispatch data. We look for related companies and every insurance policy that applies. We prepare every truck case for trial. Larry Forman has tried 50+ jury trials and won 95% of them.

Many are. Safety ratings, registration, inspection and crash history and insurance filings are public on FMCSA's websites. Property carriers' SMS percentiles and alerts are not.
It means FMCSA investigated and found that the company didn't have adequate safety management controls in place. The company can keep operating, but the rating is a warning sign.
Not once the rating becomes final. Federal rules prohibit it from operating commercial motor vehicles. FMCSA then issues an out-of-service order.
No. They show patterns, not the cause of a specific crash. They help decide what records to request and whether the company knew about problems.
A company that shuts down and reopens under a new name or USDOT number to escape a bad record. Federal rules prohibit using common ownership or control to avoid compliance.
FMCSA records cover many commercial vehicles, including larger delivery trucks and buses. See our delivery vehicle and commercial vehicle pages.
