How can I check a trucking company's safety record?

Last updated October 8, 2026.

Find the company's USDOT number, usually painted on both sides of the truck, and search it in the Federal Motor Carrier Safety Administration's free SAFER Company Snapshot. The snapshot shows the company's identity, size, cargo, any safety rating, a summary of roadside out-of-service inspections and crash information. FMCSA's Safety Measurement System adds more inspection and crash data, though some of it is hidden for property carriers.

The public record tells you who you are dealing with and whether regulators have flagged the company before. It does not show the driver's personal history or the company's internal files, which federal rules let carriers discard on a schedule. This page walks through both halves of a Las Vegas truck accident claim: what you can look up today, and what has to be requested from the company.

How do you look up a trucking company, step by step?

Find the USDOT number. A commercial truck covered by the federal safety rules must show the operating carrier's legal name or a single trade name and its FMCSA number, preceded by the letters "USDOT" (49 CFR 390.21T(b)). The marking goes on both sides of the truck and must be readable from 50 feet in daylight (49 CFR 390.21T(c)). Photograph the cab door if you can. The crash report often lists the number too; our guide to getting a Las Vegas crash report explains how to request it.
Watch for "operated by." If another company's name appears on the truck, the operating carrier's name and USDOT number must follow the words "operated by" (49 CFR 390.21T(b)(3)). The name on the trailer or on a big logo may not be the company responsible for the driver.
Search the SAFER Company Snapshot. Go to safer.fmcsa.dot.gov and search one carrier at a time by USDOT number, MC or MX number, or company name. The search is free.
Read each part of the snapshot. Note the legal name and address, how many trucks and drivers the company reports, what it hauls, its safety rating if it has one, the out-of-service inspection summary and the crash figures.
Check the Safety Measurement System (SMS). FMCSA's SMS site at ai.fmcsa.dot.gov/SMS shows inspection and crash data, investigation results and measures in its public Behavior Analysis and Safety Improvement Categories (BASICs). For property carriers, the Crash Indicator and Hazardous Materials Compliance categories are hidden from public view.
Save a dated copy. Print or save each page as a PDF with the date. The data changes; when we checked the SMS site on October 8, 2026, it showed data current as of September 25, 2026, with the next update planned for the week of November 9, 2026.
Ask the company to keep its private files. The records that matter most for a single crash are not public. A written request to preserve them should go out early, because some can be discarded within months. See what records a trucking company must keep after a crash, and for how long.

What is public, and what stays inside the company?

Record	Where it is	Public?	What it can show	Rule
SAFER Company Snapshot	safer.fmcsa.dot.gov	Yes, free	Identity, size, cargo, safety rating, out-of-service inspection summary, crash information	FMCSA SAFER page
Safety Measurement System	ai.fmcsa.dot.gov/SMS	Partly	Inspection and crash data, investigation results, public BASIC measures	FMCSA SMS page
Company registration details	Shown through SAFER	Yes, as the company reports them	Company size and operation, from the carrier's own filing	49 CFR 390.19T
Accident register	The company	No	Every reportable crash for 3 years: date, place, driver, injuries, deaths, hazmat release	49 CFR 390.15(b)
Driver qualification file	The company	No	Job application, driving records, road test, annual review, medical certificate	49 CFR 391.51(b), (c)
Inspection, repair and maintenance records	The company	No	Whether the truck was inspected and fixed on schedule	49 CFR 396.3

The registration details come from the company itself. Carriers file an identification report (Form MCS-150) and must update it every 24 months; a carrier that skips the update can face penalties and deactivation of its USDOT number (49 CFR 390.19T(b)(2), (b)(4)).

What do the safety ratings mean?

Rating	What FMCSA's definition says	What it means for you
Satisfactory	The carrier has adequate safety management controls in place and working	A starting point, not proof that this driver or this truck was safe on the day of your crash
Conditional	Controls are not adequate and could lead to the problems listed in the safety fitness standard	A sign regulators found gaps; worth asking what the company did about them
Unsatisfactory	Controls are not adequate and have resulted in those problems	Generally, the carrier is prohibited from operating commercial trucks (49 CFR 385.13(a))
Unrated	FMCSA has not assigned a rating	Not a bad mark by itself

The definitions come from 49 CFR 385.3. Ratings come from reviews such as a compliance review, which looks at hours of service, maintenance, driver qualification, licensing, insurance, accidents and other records. A safety audit of a new company does not produce a rating (49 CFR 385.3).

What changes the answer

The company is new. A new interstate carrier gets its USDOT number under an 18-month monitoring period, and a property carrier must have a safety audit within 12 months (49 CFR 385.3). A thin record may mean the company is young, not that it is safe.

The rating is unsatisfactory. Most carriers with a proposed unsatisfactory rating from a review must stop operating commercial trucks starting on the 61st day after FMCSA's notice; hazmat and passenger carriers stop on the 46th day (49 CFR 385.13(a)(1), (2)). Once the rating is final, FMCSA issues an out-of-service order (49 CFR 385.13(d)(1)). A truck on the road in breach of that order raises serious questions about the company.

The truck belongs to one company and the driver works for another. Leases, trailer interchanges and brokers can put several names on one rig. Who answers for the crash is covered in who is liable in a Nevada truck accident.

The company never leaves Nevada. A Nevada-only company may or may not appear in SAFER, and Nevada has adopted the federal safety rules for many in-state carriers by regulation (NAC 706.297). See the truck rules for Nevada companies that never leave the state.

The vehicle is lighter. The federal rules, including the marking rule, cover commercial motor vehicles, which for interstate trips generally means 10,001 pounds or more (49 CFR 390.5T). A small van may carry no USDOT number at all. Whether your crash qualifies is explained in when federal trucking law applies.

The company is based in another state. A Nevada court can still hear the case in many situations (NRS 14.065), and the steps are covered in suing an out-of-state trucking company in Nevada.

The record is clean but the crash still happened. A good record does not decide fault. In Nevada, the jury compares each party's fault, and you recover if yours is not greater than the defendants' combined share (NRS 41.141). What matters most is what happened in your crash, which is why the company's own files are worth more than any public score.

Time. An injury lawsuit in Nevada generally must be filed within 2 years (NRS 11.190(4)(e)). Some company records disappear much sooner.

For example: two names on one truck

Imagine a hypothetical driver named Rosa stopped at a light in Las Vegas when a tractor-trailer turning right clips the front of her car. Her shoulder is injured. The trailer carries the large logo of a grocery chain, but the cab door reads "operated by" another company, followed by a USDOT number. Rosa photographs both.

That night her husband searches the USDOT number on SAFER. The snapshot shows a small carrier with a conditional safety rating and several roadside inspections that ended with vehicles placed out of service. The SMS site lists recent inspections, including some with equipment violations. He saves each page as a dated PDF.

The grocery chain's insurer tells Rosa the driver is not its employee. Her photo of the door and the SAFER result point to the operating carrier instead. A preservation letter goes to that carrier asking it to keep its accident register, the driver's qualification file and the truck's maintenance records. The accident register must list the carrier's crashes for 3 years (49 CFR 390.15(b)), and the driver's file must be kept while the driver works there and for 3 years after (49 CFR 391.51(c)).

The conditional rating does not prove the carrier caused Rosa's crash. It does tell her where to look: the maintenance and inspection records, which our page on truck maintenance rules and brake failure explains. Everything in this example is invented to show how the lookup works, not a prediction for any real claim.

Common mistakes when checking a trucking company

Searching the name on the trailer. The biggest name on the rig is often a customer or the trailer owner. Search the USDOT number on the cab door first.
Reading too much into the rating. An unrated carrier is not automatically unsafe, and a satisfactory rating does not mean the driver followed the rules on the day of your crash.
Not saving a dated copy. Ratings, inspection counts and crash figures change. A screenshot without a date is hard to rely on later.
Treating the public data as the whole story. Some categories are hidden for property carriers, and the driver's own file never appears on SAFER.
Calling the company and giving a statement. A carrier's safety staff or insurer may ask how the crash happened. Your account belongs in the police report and your own claim, not in an informal call.
Waiting to ask for internal records. Federal rules let a carrier discard driver inspection reports after 3 months (49 CFR 396.11) and duty logs after 6 months (49 CFR 395.8(k)).

Our general post on evidence needed for auto accident claims covers the photos, medical records and witness details that matter in every crash, truck or not.

Frequently asked questions

Is the SAFER lookup really free?

Yes. FMCSA offers the Company Snapshot free of charge, one carrier at a time, searchable by USDOT number, MC or MX number, or company name.

Can I see the truck driver's record on SAFER?

No. SAFER and SMS report on the company. The driver's application, driving records, road test and medical certificate sit in the driver qualification file the company keeps (49 CFR 391.51(b)), which is usually obtained through formal requests once a claim or lawsuit is underway.

Why are some SMS categories missing?

Under the FAST Act of 2015, some property carrier data is no longer shown to the public. FMCSA's SMS site says the Crash Indicator and Hazardous Materials Compliance categories remain hidden, while all information on passenger carriers stays public.

Does a bad safety record prove the company caused my crash?

No. A poor record is background, not proof about your crash. It can point to questions about how the company maintained its trucks or supervised its drivers, and those questions are answered with the company's own records and the evidence from the scene.

What if the truck had no USDOT number on it?

The marking rule applies to commercial motor vehicles covered by the federal safety rules (49 CFR 390.21T(a)). A lighter truck, a truck used only inside Nevada, or a truck out of compliance may show none. The crash report, the license plate and the driver's information can still identify the company.

How much insurance does the company have to carry?

For a for-hire interstate truck of 10,001 pounds or more hauling ordinary freight, the federal minimum is $750,000, with higher amounts for hazardous materials (49 CFR 387.9). Our page on how much insurance a semi truck has to carry explains the tiers.

Can an unsatisfactory-rated company still be on the road?

It should not be once the deadline after FMCSA's notice of a proposed unsatisfactory rating has passed. For most carriers, FMCSA may allow up to 60 more days if the company is making a good-faith effort to improve (49 CFR 385.13(a)(2)). If SAFER showed that rating on the day of your crash, save that page.
