1. 1

   An official source, or no number.

   A rate or fee is shown only when it was transcribed from the administering agency's own schedule, the statute, or the regulation, and the record carries that source. Where we have no official figure (a penalty amount, say), the screen says "verify" with a link to the agency instead of guessing.

2. 2

   Two independent checks before "official".

   A fee is marked official only after a second pass against the source, separate from the first transcription. Items that failed the second pass stay marked as estimates and are never shown as a price.

3. 3

   A date on everything.

   Each record carries the date it was verified and, for periodic rates, the period it belongs to. A preliminary publication (IFTA marks its matrix "not final until" a date) is flagged as preliminary on every screen that uses it until we re-capture the final version.

The AI Copilot never computes a figure. It calls the same functions the dashboard uses and reports what they return, with the source attached. Read why in what we believe.

Official schedules are loaded for OR, NM, CT, KY, NY. No state is on estimated values. Each schedule is stamped with the quarters it applies to, so a mid-year change (New Mexico on July 1, 2026; Oregon on July 1, 2027) prices the right quarter on its own.

Rates are official: IFTA fuel matrix (2026 Q1–Q4) and the state weight-distance schedules for OR, NM, CT, KY and NY (NY uses the gross-weight method). New Mexico reflects the July 1, 2026 increase (Laws 2026, ch. 4) — Q1–Q2 2026 returns use the prior schedule. Oregon's HB 3991 simplification (effective July 1, 2027, Form 735-9928) is pre-loaded for 2027 quarters; NM, CT, KY and NY carry their current schedules into 2027 (no statutory change as of October 24, 2026). Confirm your filing quarter and reporting method before submitting.

The sentence above is the engine's own disclaimer, shown here unedited. Guides with the statutes and forms: OR, NM, CT, KY, NY.

Carrier snapshot

Legal name and DBA, operating status and out-of-service date, power units and drivers, whether the MCS-150 is current, safety rating, interstate operation and common or contract authority, and the roadside inspection history with its out-of-service rates against FMCSA's reference. Read from FMCSA's QCMobile API when a carrier is added and re-checked weekly; a change in authority is reported the day the check sees it.

Violation codes

2,412 codes from the FMCSA SMS Methodology, Appendix A violation list (SMS_AppendixA_ViolationsList.xlsx, csa.fmcsa.dot.gov), SMS methodology version 3.21, retrieved September 6, 2026. Browse them on the violation pages.

Routing and miles

Trip distances and state-line splits come from HERE truck routing, which honours truck restrictions. The public route corridors were computed on September 5, 2026. Your returns use your ELD's miles by state, not a routed estimate.

What we do not show

CSA BASIC percentiles are not public and are not shown. Insurance on file is not yet part of the carrier record. A penalty amount with no official source is shown as “verify” with the agency's link, never as a number.
