That roadside violation on your CSA record may not belong there. Wrong inspection reports, misidentified vehicles, violations written on the wrong carrier — they happen more often than most carriers realize. The DataQs process exists to fix exactly these errors. And if you walk in with the right evidence, you usually win.

What DataQs is

DataQs is FMCSA's Request for Data Review system. Anyone — carrier, driver, attorney — can challenge a crash or inspection record on the FMCSA database. The challenge goes to the state agency that submitted the report, which has 24 days to respond with either a confirmation, a correction, or a rejection.

The database change flows through to your SMS / CSA profile within 30–60 days of resolution. A removed violation lowers the Behavior Analysis and Safety Improvement Category (BASIC) score it was feeding.

What's actually challengeable

  • Wrong carrier. The violation was written on your DOT number but the vehicle or driver belongs to another carrier.
  • Factually incorrect. The violation description doesn't match what actually happened — wrong code cited, wrong measurement recorded, non-existent defect.
  • Regulation misapplied. The regulation cited doesn't apply to your operation or the situation.
  • Duplicate or data entry error. The same violation appears twice, or the carrier / vehicle data was transcribed incorrectly.
  • Crash not preventable. The Crash Preventability Determination Program (CPDP) lets carriers challenge crashes in specific eligible categories — see the full CPDP section below.

Crash Preventability Determination Program (CPDP)

The CPDP is a separate FMCSA program that runs through the DataQs portal but has its own rules, eligibility categories, and outcome. It's become permanent and has expanded since it launched in 2017 — if your carrier has been hit with a crash that wasn't your driver's fault, this is the process that gets it off your Crash Indicator BASIC.

What happens when a crash is determined Not Preventable:

  • The crash stays visible on your carrier profile (it happened — FMCSA doesn't erase the record).
  • The crash is removed from your SMS Crash Indicator BASIC calculation — it stops influencing your percentile score.
  • It's also flagged Not Preventable in the Pre-Employment Screening Program (PSP), so when future employers run your driver's PSP record, the crash is visibly marked.
  • If determined Preventable, the crash stays in the SMS calculation. If the review is "Undecided" (insufficient evidence), same outcome as Preventable for SMS purposes.

The 21 eligible crash categories (current as of FMCSA's December 2024 Eligibility Guide — FMCSA expanded CPDP on December 1, 2024, adding several new categories and a hard start date for those):

  1. Struck in the Rear — striking vehicle was directly behind the CMV
  2. Struck on the Side at the Rear — struck between the CMV's rear wheels and back corner
  3. Struck on the Side (Same Direction) — side impact by a vehicle traveling same direction (eligible for crashes on or after Dec 1, 2024)
  4. Wrong Direction — striking vehicle completely in the wrong lane
  5. U-Turns and Illegal Turns — U-turn or illegal-turn crash, documented in PAR
  6. Parked or Legally Stopped — CMV parked (including unattended) or stopped at a traffic control device
  7. Failure of the Other Vehicle to Stop — other vehicle failed to stop at a control device or in heavy traffic
  8. Under the Influence — other driver arrested/charged with DUI, documented in PAR
  9. Medical Issue (other driver) — other driver's medical event caused the crash, per PAR
  10. Falling Asleep (other driver) — other driver fell asleep, per PAR
  11. Distracted Driving (other driver) — other driver distracted (phone, GPS, eating), per PAR
  12. Cargo/Equipment from Another Vehicle — struck by cargo, tire, trailer that came off another vehicle
  13. Debris / Infrastructure Failure — fallen rocks/trees/debris or infrastructure failure (e.g., fallen power line)
  14. Animal Strike — the CMV struck an animal (not: swerved to avoid and hit something else)
  15. Suicide / Suicide Attempt — documented in PAR or other evidence
  16. Struck by Vehicle Entering Road from Private Drive/Parking Lot — other vehicle exiting uncontrolled driveway (eligible Dec 1, 2024+)
  17. Another Motorist Lost Control of Vehicle — documented in PAR narrative/code sheet (eligible Dec 1, 2024+)
  18. Non-Motorist — pedestrian, cyclist, scooter, or similar outside a crosswalk (eligible Dec 1, 2024+; earlier crashes submit under Rare or Unusual)
  19. Rare or Unusual — catch-all for rare crash types (e.g., plane landing on roadway). Weather events are NOT eligible here.
  20. Video Submission — video conclusively shows pre-/crash/post-crash, CMV driver not at fault (eligible Dec 1, 2024+, and only if crash doesn't fit another category)

5-year lookback: FMCSA cannot review crashes older than 5 years. If the crash predates that window, a CPDP filing won't be accepted.

Get the authoritative source documents: the FMCSA Eligibility Guide (December 2024), Submitter Guide, FAQs, and Overview Presentation are available directly, and are mirrored in the Forms tab inside your X3 dashboard. X3's DataQs agent references the December 2024 guide as its canonical eligibility source.

Crashes that don't fit one of these 21 categories are not eligible for CPDP — they can still be reviewed through standard DataQs if there's a factual error, but they won't get the SMS-removal benefit.

The single most important piece of evidence

The Police Accident Report (PAR). Without it, FMCSA almost always returns "Undecided" — the reviewer has no way to verify the crash facts. Pull the PAR immediately after any crash. If there isn't one yet, delay the CPDP filing until it's available.

Evidence that supports a CPDP filing (in addition to the PAR):

  • Dashcam or surveillance video showing the impact
  • Photographs of final vehicle positions and damage
  • Written statement from the driver (what they saw, heard, did)
  • Witness statements if available
  • Court documents showing the other driver was cited, charged, or convicted (DUI, wrong-way, failure to yield, etc.)
  • Medical records (for "driver had a medical emergency" category)
  • ELD records showing CMV speed, position, and whether CMV was in motion at time of impact

How to file:

  1. Go to dataqs.fmcsa.dot.gov and select Request for Review of a Crash, then Request a Preventability Determination.
  2. Identify the specific eligible crash category from the list above.
  3. Upload the PAR and supporting evidence.
  4. Write a brief narrative tying the evidence to the category — e.g., "CMV was legally stopped on shoulder (see PAR Section 4, photo attached). Striking vehicle was cited under state statute 257.626 for careless driving."
  5. Submit. FMCSA typically responds within 60 days.

If denied or "Undecided": you can request a second review with additional evidence within one year of the original determination. Fresh evidence that wasn't available initially (a late-arriving dashcam pull, a court conviction that post-dated the first review) is the most persuasive path.

CPDP vs. standard DataQs — when to pick which:

  • Use CPDP when the crash fits an eligible category and you want it removed from your Crash Indicator BASIC.
  • Use standard DataQs when there's a factual error in the record itself — wrong carrier, wrong vehicle, wrong violation code, wrong date.
  • A crash that's both factually wrong and fits a CPDP category should be filed under CPDP first — cleaner path to SMS removal.

What isn't challengeable

  • A violation that was written correctly but you disagree with the severity weighting.
  • A violation that has been adjudicated in court and dismissed — DataQs handles the FMCSA record; court dismissal doesn't automatically clear the FMCSA database.
  • Anything older than the inspection report retention period (typically 24 months for SMS purposes).

The evidence that actually wins

  1. The Driver Vehicle Examination Report (DVER). The original inspection form the officer filled out. Get it at the scene if possible; request it from the state agency if not. Read every line.
  2. Photographs. Time-stamped, taken at the scene, showing the specific defect as written. A tire-depth violation written at 2/32" should have a tread-depth gauge photo if you want to challenge it.
  3. Repair invoices and mechanic statements. If the inspector wrote up a brake adjustment violation, a mechanic's inspection of the same brake within 24 hours showing it was within adjustment is powerful.
  4. ELD data. For HOS violations, the actual RODS from your ELD vendor. Mismatches between what the officer recorded and what the ELD captured are common.
  5. Court documents. Dismissal orders, reduction of charges, plea documents. DataQs staff want to see the adjudication outcome even though they don't automatically defer to it.
  6. Statements from witnesses. The driver's account, dispatcher statement, other involved parties. Written, signed, dated.

How to file

File at dataqs.fmcsa.dot.gov. You'll need the inspection report number, your DOT number, and the specific violation you're challenging. One challenge per violation — you can't bundle.

Write the narrative tight. State the specific violation as written, state the factual or legal error, and list the evidence you're submitting. State agencies process hundreds of these per month; a clear two-paragraph challenge with attached evidence gets faster attention than a three-page narrative.

What to expect after filing

The state agency has 24 days to respond. Most respond within 10–14 days for straightforward challenges. Expect one of four outcomes:

  • Approved. Violation removed or corrected.
  • Denied. State agency stands by the report. You can appeal once with additional evidence.
  • Partial. Some aspect of the violation is corrected (e.g., severity adjusted, measurement changed) but not fully removed.
  • Duplicate / outside scope. Returned without action.
