Quick answer: Small carriers can run tighter operations without buying anything, using free government lookups and calculators for safety scores, IFTA fuel-tax math, cost-per-mile, and diesel prices. The most essential ones are the FMCSA SAFER and CSA lookups (for your own DOT number and for vetting brokers/shippers), the IRS standard mileage rate page, your base state's IFTA fuel tax rate schedule, and the U.S. Energy Information Administration's weekly diesel price report. Bookmark these, check them on a schedule, and pair them with a system that tracks compliance dates automatically.
Key takeaways
- The Federal Motor Carrier Safety Administration (FMCSA) publishes carrier safety data for free through SAFER (Safety and Fitness Electronic Records) and the CSA (Compliance, Safety, Accountability) program — both are official government lookups, not paid services.
- The International Fuel Tax Agreement (IFTA) requires quarterly filing, and each member jurisdiction publishes its own current tax rate per gallon — these rates change quarterly and must come from the IFTA Inc. rate chart, not memory.
- The U.S. Energy Information Administration (EIA) publishes a weekly average diesel price report every Monday, which is the standard reference point most carriers use for fuel surcharge negotiations.
- Cost-per-mile tracking catches rate problems before they sink a lane; a load that looks profitable at a glance can be a loss once fuel, tolls, and deadhead miles are counted.
Which free FMCSA lookups should every carrier bookmark?
The two you'll use most are SAFER and the FMCSA Company Snapshot, both run by the FMCSA. SAFER gives you a quick public record of any carrier's DOT number, operating status, and basic safety data — useful both for checking your own listing and for vetting a broker or shipper before you haul for them.
Beyond that, a few more FMCSA and Department of Transportation tools are worth having saved:
- FMCSA Licensing & Insurance (L&I) system — confirms a carrier's active authority and insurance filings on record.
- CSA SMS (Safety Measurement System) — shows your carrier's scores across the seven BASIC categories (unsafe driving, hours-of-service compliance, vehicle maintenance, and others tracked by FMCSA).
- FMCSA National Registry of Certified Medical Examiners — confirms whether a medical examiner who cleared a driver's DOT physical is on the certified list.
- PSP (Pre-Employment Screening Program) — for a small fee, pulls a driver applicant's crash and inspection history directly from FMCSA records; useful during hiring even though it isn't free.
Don't skip this: if your CSA scores are climbing, don't wait for a compliance review to find out why. FMCSA updates SMS data monthly, and a rising score in any BASIC category is worth investigating immediately — it's often the first visible sign of a maintenance gap or a driver logging issue.
How do I calculate IFTA fuel tax without paying for software?
You calculate it by tracking miles driven and fuel purchased in every IFTA jurisdiction, then applying that quarter's published tax rate for each state or province. IFTA Inc., the group that administers the agreement among U.S. states and Canadian provinces, publishes a rate chart every quarter — and that's the number you need, not last quarter's rate, since it changes.
The manual version of this looks like:
- Log every fuel purchase with date, location, gallons, and price paid.
- Track miles driven in each jurisdiction using odometer readings or a trip log.
- Pull the current quarter's tax rate for each jurisdiction from the IFTA Inc. rate chart.
- Calculate net tax owed or credited per jurisdiction, then total it for your quarterly return.
- File with your base jurisdiction — the state where your IFTA license is issued — by the quarterly deadline.
This is the part of trucking paperwork most likely to eat an entire Saturday for an owner running two or three trucks. If you're doing it by hand across multiple states each quarter, it's worth reading how automated IFTA reporting compares to spreadsheets in 5 Signs Your Trucking Company Has Outgrown Spreadsheet Dispatching.
What free calculators help figure out true cost per mile?
There isn't one official government cost-per-mile calculator, but you can build an accurate one yourself using a few publicly documented numbers. Cost per mile means every dollar it costs to run a truck one mile — fuel, driver pay, insurance, maintenance, permits, and fixed overhead — divided by total miles run.
The inputs worth tracking:
| Cost category | Where the number comes from |
|---|---|
| Fuel | Your actual fill-up receipts, or EIA weekly diesel average as a planning estimate |
| Driver pay | Per-mile rate, percentage pay, or hourly rate from your pay agreements |
| Insurance | Your policy's annual premium divided by expected annual miles |
| Maintenance & repairs | Trailing 12-month actual spend divided by miles run |
| Permits, plates, IFTA | Annual fixed costs divided by miles run |
| Tolls | Actual toll transponder statements |
Once you know your true cost per mile, you can compare it against a rate confirmation before you accept a load — a $2.10/mile rate on a lane where your true cost is $1.95 leaves only 15 cents of margin before you account for deadhead. If a truck runs 100 miles empty to pick up that load, the real margin on that trip can vanish entirely.

Where can I check current diesel prices for fuel surcharge math?
The U.S. Energy Information Administration publishes a weekly U.S. average diesel price report, updated every Monday, and it's the most commonly referenced source for setting or verifying fuel surcharges. Many shippers and brokers build fuel surcharge tables directly off the EIA's weekly national or regional average, so knowing that number before you negotiate a rate confirmation puts you on equal footing.
A few things worth knowing about how this number gets used:
- EIA reports both a national average and regional averages — check which one your shipper's contract references before assuming the number matches.
- Fuel surcharge tables vary by shipper; there's no single federal formula, so always confirm the base rate and the surcharge trigger point in your own contract.
- AAA also publishes daily gas and diesel price averages, which some regional shippers use instead of the weekly EIA figure — worth checking if your contract cites AAA specifically.
Given how volatile diesel prices have been at points this year, checking the EIA report weekly — not monthly — is worth the two minutes it takes.
What should I check before accepting a load from a new broker?
Before you accept a load from a broker or shipper you haven't hauled for, confirm their operating authority and insurance are active using the FMCSA's Licensing & Insurance system described above. This takes under a minute and catches the small number of brokers operating without current insurance on file — a real exposure if a claim happens mid-load.
A quick pre-load checklist:
- Verify the broker's MC number is active in FMCSA's L&I system.
- Confirm your own DOT number and authority show "active" in SAFER, since a lapse can happen without you noticing.
- Check that the rate confirmation matches the verbal or emailed rate — discrepancies should be resolved in writing before you dispatch.
- Save the rate confirmation and any accessorial terms (detention, layover, TONU) before the driver arrives at pickup.
- Log the load's origin and destination miles against your cost-per-mile number to confirm the lane is worth running.
This kind of load-by-load discipline is exactly where a lot of small carriers lose money without realizing it — not on one bad load, but on a slow accumulation of loads accepted without checking the math. If your dispatch process still runs on phone calls and a notebook, 5 Signs Your Trucking Company Has Outgrown Spreadsheet Dispatching walks through when it's time to change that.
What free resources cover driver hiring and compliance documents?
The FMCSA's Pre-Employment Screening Program and National Registry of Certified Medical Examiners (both mentioned above) cover the two most important hiring checks: driving history and DOT physical certification. Beyond those, the FMCSA publishes its full DOT compliance checklist — hours-of-service rules, DVIR requirements, drug and alcohol testing program rules — directly on its site, and it's the authoritative source any time you're unsure whether a document or process is still current.
The pattern worth building into your operation isn't just bookmarking these tools — it's checking them on a recurring schedule instead of only when something goes wrong. A compliance document that expires quietly is far more expensive than one that's caught two weeks ahead. If you want the vocabulary straight before diving into any of these systems, Trucking Software Glossary: TMS, ELD, IFTA, DVIR and More defines the terms used across all of them in plain language.
Bookmarking these tools solves the lookup problem. It doesn't solve the tracking problem — knowing a DVIR needs review, or that a driver's medical card expires in 12 days, still requires someone to remember to check. Yolda is built for that second half: a driver mobile app and web workspace that flags compliance documents before they expire, runs quarterly IFTA calculations from entered or scanned fuel data, and routes every driver report — inspections, DVIRs, receipts — through one review queue instead of a stack of paper.
If your team is still juggling free tools and spreadsheets to hold all this together, reach out to Yolda to see what a purpose-built system looks like for a fleet your size.
