States are rated on a monthly basis on the completeness, timeliness, accuracy, and
consistency of State-reported crash and roadside inspection data in MCMIS.
SSDQ Evaluation Adjusted
The Non-Fatal Crash Completeness (NFCC) measure was removed from the Data Quality methodology. However, the evaluation will continue to be available as an improvement tool to help States evaluate the completeness of reporting non-fatal crash records. Visit the Continuous Improvement area for more details.
FARS/MCMIS Matching Tool Updated
The FARS record set now contains records from the FARS’ Parkwork data set, which includes information about parked and working vehicles involved in fatal crashes. Visit the Matching Tool Description area for more details.
The FMCSA uses safety event data provided by the States to evaluate their safety programs.
Since there is variability among States in the reporting of crash and roadside inspection
data, a State Safety Data Quality (SSDQ) evaluation has been developed to evaluate the completeness,
timeliness, accuracy and consistency of this State-reported data in the Motor Carrier Management
Information System (MCMIS). The evaluation consists of eight performance measures and one overriding
performance indicator. Each State will have a rating of "Good", "Fair" or "Poor" for each measure
and rating. This evaluation will be updated monthly to reflect improvements in crash and roadside
The criteria for reporting crashes to FMCSA is included in the following
