State Data

Data-driven safety systems are vital to informing decisions that improve safety on the Nation’s roads—FMCSA relies on the States for accurate and comprehensive data on eligible crashes and inspections to focus resources to further reduce crashes. We can’t do it without you.

Each month, States are rated on reporting of safety data—this page provides States with a robust resource to view their ratings and measures, and learn how to improve data quality performance.

Measures: Crash Accuracy

89%
CRASH
ACCURACY
89% of your State’s evaluated crash records matched with a carrier that is registered with FMCSA. These crashes occurred between 01/01/2016 and 12/31/2016. Your rating is fair because your percentage is between 85%-94%. Learn how this rating is calculated.
info
Why this matters

Accurate carrier information helps FMCSA prioritize carriers for intervention that pose the greatest safety risk. Crash records matched to a carrier that is registered with FMCSA are included on a carrier’s safety record and are used by the SMS to assess carrier safety performance.

Data Source: MCMIS fatal and non-fatal crash records for 12 months representing interstate carriers and intrastate carriers transporting hazardous material, and includes large trucks and buses. (Excludes crash records entered per FMCSA’s "Procedures for Entering Crashes without Carrier Identification into SAFETYNET")
How this rating is calculatedClose Popup

The Crash Accuracy measure evaluates 12 months of data to determine your State’s rating. A record is evaluated if the date of the crash event—not the date of upload to FMCSA—falls within that 12-month range. As shown below, the range begins 15 months before the evaluation month, but excludes the most recent three months of data. In the example, the January 2015 evaluation looks at the 12-month event date range November 1, 2013, through October 31, 2014; crashes that occurred after October 31, 2014, were not included in the evaluation.

evaluation period

This measure evaluates crash records representing interstate carriers and intrastate carriers that carry hazardous materials, and includes large trucks and buses. It analyzes the crash records with carrier information that matched to a carrier in the Motor Carrier Management Information System (MCMIS).

The percentage of matched records is determined by dividing the number of matched records by the number of total records evaluated. If the percentage of matched records is

  • 95% or more, the rating is GOOD
  • Between 85% and 94%, the rating is FAIR
  • Less than 85%, the rating is POOR, unless the number of records reported is less than 15, in which case the rating is INSUFFICIENT DATA.
