About & Data Sources

Published by Idaho Fidelity. This tracker documents CDL-vehicle incidents across the United States from 2000 to present. It is built on public government data, public news reporting, and official investigative records. All sources are cited on every incident. Nothing is inferred β€” if a source doesn't say it, we don't either.

What We Track

Any incident involving a vehicle requiring a Commercial Driver's License (CDL) β€” generally vehicles with a gross vehicle weight rating over 26,000 lbs. This includes semi trucks, tanker trucks, flatbeds, dump trucks, and other large commercial vehicles. School buses and passenger carriers are outside current scope.

Coverage: 2000 to present, all 50 states. Use the state filter on the map or incident table to view Idaho-only or any other state's data.

Fault Classification Rules

Fault is classified strictly by documented facts from primary sources. No editorial judgment is applied.

Foreign Driver Flag

The foreign driver flag is set only when a source explicitly documents that the driver held a non-domiciled CDL, was identified as a foreign national, or immigration status was a documented factor in the incident record. It is never inferred from a name, ethnicity, or assumed from any other characteristic. The note field on each flagged record shows exactly what the source stated.

This data point exists because federal agencies including the FMCSA, NTSB, and DOT have documented a pattern of non-domiciled CDL issuance issues and enforcement gaps. Sources are cited. We report what is documented.

Cost Methodology

Two cost figures are shown for every incident where applicable:

FieldDefinitionColor
Stated CostDollar figure reported in source material (insurance, cleanup contract, rebuild cost, etc.)White β€” as reported
Estimated CostCalculated using FHWA Comprehensive Crash Cost model (2024 dollars)Yellow β€” estimated

FHWA baseline values used:

CategoryPer-Unit Cost (2024)
Fatal crash (per fatality)$12,000,000
Injury crash (per crash)$600,000
Property Damage Only crash$12,000

These are conservative estimates. Actual costs including emergency response, road closure, freight loss, environmental cleanup, and litigation often exceed these figures. When follow-up reporting provides actual cost figures, the stated cost field is updated.

Company Per-Capita Rates

Raw incident counts favor singling out large carriers simply because they have more drivers and more trucks on the road. The per-capita rate (incidents per 100 drivers) provides a fairer comparison. Both are shown on the Companies page.

Driver count data source priority:

This is not a complete carrier safety record. The FMCSA Safety Measurement System (SMS) contains full inspection and crash data for all registered carriers. This tracker focuses on incidents with public documentation and named sources.

Data Sources

NHTSA Fatality Analysis Reporting System (FARS)
Census of all fatal motor vehicle crashes on U.S. public roadways, maintained by the National Highway Traffic Safety Administration. Considered the most reliable national fatal crash database. Used for fatal incident baseline data from 2000 to present.
FMCSA Motor Carrier Census
Public dataset of all USDOT-registered motor carriers including driver counts, CDL counts, power units, and safety ratings. Updated daily. Accessed via FMCSA Open Data Socrata API. Used for company per-capita calculations.
FMCSA SAFER System
Safety and Fitness Electronic Records system. Provides company snapshots including safety ratings, crash histories, inspection summaries, and operating authority. Used for carrier enrichment on individual incident records.
FMCSA SMS Monthly Crash Download
Monthly updated publicly available crash data file used in FMCSA's Safety Measurement System calculations. Contains federally reportable crashes (tow-away, injury, or fatality) by carrier USDOT number.
NTSB Accident Reports
National Transportation Safety Board full investigation reports for significant commercial vehicle accidents. Primary source for official fault determinations in high-profile incidents.
Public News Reporting
State highway patrol press releases, local news outlets, and national trucking trade press (Transport Topics, Overdrive, Freightwaves, Truckers News, Fleet Owner, Land Line Magazine). Every incident includes direct source links. No incident is entered without a verifiable source.

Update Schedule

The scraper runs on the 1st and 15th of each month via GitHub Actions. New incidents are placed in a pending review queue and opened as a pull request for editorial review before being published to the live database. No incident is published automatically without human review.

Corrections & Submissions

If you have a correction, an incident to report, or documentation that should update an existing record, open an issue on GitHub or contact Idaho Fidelity directly. All updates require source documentation.
