To focus Agency resources and reduce crashes, FMCSA relies on our State partners to provide accurate, comprehensive data. Each month, FMCSA rates States on their reporting of safety data. This page allows States to view their ratings and measures and learn how to improve data quality performance.
FMCSA recently re-evaluated the SSDQ measures and identified changes to ensure the data used to inform safety are of the highest quality possible. Log in with your FMCSA Portal user ID and password to preview these changes.

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 initial upload 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 records. These records were used to calculate the leading indicator, which forecasts where measures may be trending.
In the example, the January 2019 evaluation looks at the 12-month event date range November 1, 2017, through October 31, 2018. Inspections that occurred after October 31, 2018, were used to calculate the leading indicator.
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
