Crash Indicator Calculation Detail

The Crash Indicator BASIC is one of 7 BASICs in SMS. It's calculated differently than violation-based BASICs.

What crashes count

DOT-recordable crashes per § 390.5:

  • Fatality (any party)
  • Bodily injury requiring immediate medical treatment away from scene
  • Disabling damage requiring tow-away

Severity weighting

  • Fatal crash — 3 points
  • Injury crash — 2 points
  • Tow-away crash — 1 point

Time weighting

  • Crashes in past 0-6 months: 3× weight
  • Crashes in past 6-12 months: 2× weight
  • Crashes in past 12-24 months: 1× weight

Calculation formula (simplified)

Crash Score = Sum of (Severity × Time Weight) for all crashes in past 24 months
Crash Indicator Percentile = Carrier's Crash Score relative to peer group

Crash Preventability Determination Program

Started 2020, allows carriers to challenge crashes for preventability. If FMCSA determines crash was non-preventable:

  • Crash still counts in your record
  • But preventability flag is published
  • May influence external observers (insurance, customers)

What qualifies for preventability review

  • Hit while parked
  • Driver hit by drunk driver
  • Driver hit by impaired/under-the-influence driver
  • Driver hit by suicide
  • Driver hit by red-light or stop-sign-running other party
  • Driver hit while stationary in traffic
  • Driver hit by animal
  • Driver hit by infrastructure failure (tree falls, bridge collapse)

How to file

  • Apply via FMCSA Crash Preventability Determination Program (online)
  • Provide documentation (police report, dashcam footage, witness statements)
  • FMCSA reviews and issues determination

Compass support

Compass CSA module:

  • Imports crash data from carrier reports
  • Flags crashes eligible for preventability review
  • Tracks the determination outcome
  • Adjusts your dashboard to reflect non-preventable status (still in BASIC, but flagged)

CFR citations

  • 49 CFR § 385.4
  • FMCSA SMS Methodology — Crash Indicator
  • FMCSA Crash Preventability Determination Program

How Compass surfaces this

Searchable in Compass Ask. Runs against the carrier's actual fleet data when invoked from the relevant tracker. Read-only; no actions without explicit user approval.

Use this skill when the user asks about accident claims management — first-notice-of-loss procedures, working with insurance adjusters, claim severity classification, subrogation, claim closure timelines, and how to influence claim outcomes. Different from accident-investigation-playbook (which covers facts); this covers the insurance + claim side.

Use this skill when the user asks how to investigate a CMV accident — what to do at the scene, the first 24 hours, evidence preservation, who to call, preventability determination, ELD data preservation, dash cam review, witness interviews, working with insurance + attorney, and how to build a learning culture from incidents. Reference 49 CFR 392.7 + insurance industry best practices.
