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.

ACCURACY
97% of your State’s evaluated inspection records have a valid VIN for the first vehicle unit. These inspections occurred between 01/01/2016 and 12/31/2016. Your rating is good because your percentage is greater than or equal to 85%. Learn how this rating is calculated.

Why this matters

Accurate VINs help FMCSA associate inspections to the right vehicle, which can help prioritize carriers or drivers for interventions that pose the greatest safety risk.

How this rating is calculatedClose Popup

The Inspection Vehicle Identification Number (VIN) Accuracy measure evaluates 12 months of data to determine your State’s rating. A record is evaluated if the date of the inspection 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; inspections that occurred after October 31, 2014, were not included in the evaluation.

evaluation period

This measure evaluates roadside inspection (Levels 1-6) records representing interstate and intrastate carriers, and includes large trucks and buses. It analyzes the VIN of the first vehicle unit only–all trailing units are excluded. A VIN is invalid if it is less than 17 characters, contains invalid character(s), or does not pass a checksum analysis; for this measure, a VIN that contains the same 17 numbers, such as all 9’s, is considered invalid.

The rating percentage is determined by dividing the number of records with valid VINs by the number of total records evaluated. If the percentage of accurate records is

  • 85% or more, the rating is GOOD
  • Between 70% and 84%, the rating is FAIR
  • Less than 70%, the rating is POOR.
