🔎 Carrier Safety

How to Check a Trucking Company Before You Sign On

A 15-minute background check on any carrier: USDOT and MC numbers, authority, safety rating, out-of-service rates, insurance and what other drivers say.

By the SemiLife teamUpdated 7 min read

Key takeaways

  • Get the carrier's USDOT number first. Everything public about a carrier — authority, inspections, crashes, insurance — hangs off that number.
  • Active authority plus insurance on file is the bare minimum for a for-hire carrier. No authority or a pending insurance cancellation is a stop sign.
  • Most carriers are unrated. A Conditional or Unsatisfactory safety rating is worth asking about; no rating at all is normal.
  • Compare the carrier's out-of-service rates with the national average printed on SAFER, and look at how many inspections the rate is based on.
  • Public data shows how a carrier runs trucks. Driver reviews and a few hard questions show how it treats people. You need both.

Before you put your name on a contract, move your stuff into a truck or drive 800 miles to orientation, spend fifteen minutes on the company. Almost everything you need is public, free and tied to one number. This guide walks through it in the order that saves the most time: kill the obvious bad options first, then dig into the details.

Step 1: Get the right USDOT number

Ask the recruiter for the company's USDOT number (and MC number if it hauls for-hire freight). A legitimate carrier gives it out without hesitation — it's painted on the truck doors anyway.

Then confirm you have the right company. Many carriers have near-identical names, and some fleets run several entities. On FMCSA's SAFER Company Snapshot or on a SemiLife carrier page, check that:

  • The legal name and DBA match what the recruiter told you.
  • The address and phone make sense (a terminal, not a random apartment for a "500-truck fleet").
  • The number of power units and drivers roughly matches the size they claim.

If the recruiter's story and the government record don't line up, stop and ask why. Sometimes there's an honest answer — a parent company, a newly formed entity — but you want to hear it before you sign.

Step 2: Check operating authority and insurance

A for-hire interstate carrier needs active operating authority and liability insurance on file with FMCSA. You can see both in FMCSA's Licensing & Insurance system and in the authority section of a SemiLife carrier page.

What to look for:

  • Authority status: Active. "Inactive," "Revoked" or "Not authorized" on a company that says it hauls freight across state lines for customers is a serious problem. (Private carriers that haul only their own goods, and intrastate-only carriers, don't need for-hire authority, so read the status in context.)
  • Insurance on file. The federal minimum for most general-freight carriers is $750,000 in public liability coverage, higher for oil and certain hazmat loads (49 CFR 387.9). Many customers require more.
  • Pending cancellations or revocations. SAFER links to pending insurance cancellations. A carrier whose insurance is about to lapse can be shut down — and you can be the one stranded.
  • Authority age. Very new authority isn't automatically bad, but it means little track record. New carriers are in FMCSA's New Entrant program and get a safety audit in their first year.

Step 3: Look at the safety rating — and don't panic if there isn't one

FMCSA assigns a safety rating only after investigating a carrier. There are three ratings:

  • Satisfactory — adequate safety management controls were found.
  • Conditional — controls were found inadequate in some way.
  • Unsatisfactory — controls are inadequate, and the carrier will be ordered out of service if it doesn't fix things in time.

Most carriers are unrated, simply because they've never had an investigation. That's normal. What you want to know:

  • If it's Conditional, when was the rating and what changed since? Ask the recruiter directly.
  • If it's Unsatisfactory, or the carrier is under an out-of-service order, walk away.
  • A Satisfactory rating from twenty years ago says little about the company today. Look at recent inspections.

Our plain-English guide to safety ratings and CSA BASICs goes deeper.

Step 4: Read the inspection and out-of-service numbers

This is where the real day-to-day picture lives. SAFER and SemiLife show roadside inspections for roughly the last 24 months, split into driver, vehicle and hazmat inspections, and how many ended with an out-of-service (OOS) order.

An OOS order means a problem serious enough that the driver or truck couldn't legally continue until it was fixed — bad brakes, a flat tire, too many hours, no medical card.

How to read the numbers without fooling yourself:

  1. Compare with the national average. SAFER prints national average OOS rates right under the carrier's own rates. In recent snapshots the vehicle average has been in the low-20s percent and the driver average in the mid-single digits. Use the average printed on the day you look.
  2. Check the sample size. A 50% vehicle OOS rate from 2 inspections means one bad day. A 35% rate from 400 inspections means a maintenance problem.
  3. Vehicle vs. driver. A high vehicle OOS rate points at shop and equipment. A high driver OOS rate points at hours-of-service pressure, logs or hiring standards. Both affect you.
  4. Look for a trend. If the company just bought new trucks, old numbers may overstate the problem. Ask.
What you seeWhat it usually means
Vehicle OOS well above the national average, many inspectionsEquipment isn't being kept up. Ask about the shop, PM schedule and truck age.
Driver OOS well above averagePossible HOS pressure or loose hiring. Ask how dispatch plans around your clock.
Very few inspections for a large fleetPossibly lots of local or private work, or a newer company. Not good or bad by itself.
Low OOS rates with plenty of inspectionsUsually a well-maintained fleet. A good sign.

Step 5: Check crashes

The snapshot also lists crashes over the last 24 months: total, with injuries, with fatalities, and tow-aways. Raw crash counts don't say who was at fault, and big fleets drive enormous miles, so compare crashes against fleet size and inspections rather than in isolation. A small fleet with several injury crashes in two years deserves a direct question.

Step 6: Find out how the company treats drivers

Government data tells you about trucks and compliance. It doesn't tell you whether settlements are short, whether home time happens, or whether the "brand-new trucks" are 2016s. For that:

  • Read driver reviews on the company's SemiLife page. Look for repeated themes — pay problems, forced dispatch, broken promises on home time — not one-off rants.
  • Ask the Q&A. Post a specific question ("What do solo drivers on the dedicated account actually average per week?") and see who answers.
  • Talk to current drivers at a terminal or truck stop. Ask what they wish they'd known before they started.
  • Get everything in writing. Pay rate, miles, home time and any contract terms. Use our recruiter question checklist.

Red flags that should end the conversation

  • They won't give you a USDOT number, or the number belongs to a different company.
  • Authority is inactive or revoked, or insurance is being cancelled.
  • Unsatisfactory rating or an active out-of-service order.
  • They want money up front for a job — an "application fee," "training deposit" or "equipment deposit" before you've seen a contract.
  • They pressure you to sign a lease-purchase on the spot, or won't let you take the contract home. (See lease-purchase red flags.)
  • They ask you to run without logging hours properly or tell you to "fix it later."

A 15-minute checklist

  • USDOT number matches the company name, address and size the recruiter described
  • Operating authority active (for for-hire interstate carriers)
  • Liability insurance on file, no pending cancellation
  • Safety rating checked (unrated is normal; Conditional needs an explanation; Unsatisfactory is a no)
  • Driver and vehicle OOS rates compared with the national average, with sample size in mind
  • Crash history read against fleet size
  • Driver reviews and Q&A read on SemiLife
  • Pay, miles, home time and contract terms in writing

Do this for every company on your shortlist. The good ones look good on paper too — and it's a lot cheaper to find out now than after orientation.

Frequently asked questions

What is the difference between a USDOT number and an MC number?+

The USDOT number identifies the company and its safety record. The MC (docket) number is tied to operating authority for for-hire interstate carriers. A carrier hauling other people's freight across state lines usually has both. FMCSA has discussed phasing out MC numbers, but as of October 2026 they are still issued and still show up on SAFER and in the licensing system.

Is a carrier with no safety rating unsafe?+

Not by itself. A safety rating is only issued after an FMCSA investigation, and most carriers have never had one, so they show as unrated. Judge an unrated carrier by its inspections, out-of-service rates, crashes and reviews instead.

How new is too new for a carrier?+

There is no rule, but brand-new authorities have little history to judge. New carriers go through FMCSA's New Entrant program and a safety audit. If a company got its authority a few months ago, ask harder questions about pay schedule, insurance and who maintains the equipment.

Where can I see what drivers say about a company?+

SemiLife carrier pages include driver reviews and Q&A next to the public FMCSA data. Read several reviews, look for patterns rather than one angry post, and ask current drivers at the fuel island or terminal if you can.

Can I check a company with only its name?+

Yes, SAFER lets you search by name, but names are easy to confuse — many carriers have similar names. Ask the recruiter for the USDOT number and confirm the name, address and phone match.
