Your rating is

Good (100-90)

Why is This My Rating?
Your Crash VIN Accuracy rating is good because your percentage is between 90-100%.
How is This Calculated?
99% of your State's evaluated crash records have a valid VIN. These crashes were initially uploaded between 03/01/2023 and 02/29/2024. Learn more about how this rating is calculated.
How to Improve My Crash VIN Accuracy?
Use the data dashboard below to dig deeper into your data or access the following supplemental reports:
Data Source: MCMIS crash records for 12 months representing interstate and intrastate carriers, and includes large trucks and buses.

The Crash 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 initial 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. These records were used to calculate the leading indicator, which forecasts where measures may be trending.

In the example, the July 2022 evaluation looks at 12-months of uploads from May 1, 2021, through April 30, 2022. Crashes that were uploaded after April 30, 2022, were used to calculate the leading indicator.

evaluation period

This measure evaluates crash records representing interstate and intrastate carriers, and includes large trucks and buses. It analyzes the VIN reported on the crash record. 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

  • 90% or more, the rating is GOOD
  • Between 80% and 89%, the rating is FAIR
  • Less than 80%, the rating is POOR.
