States are rated on a monthly basis on the completeness, timeliness, accuracy, and
consistency of State-reported crash and roadside inspection data in MCMIS.
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 nine 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
