SSDQ Continuous Improvement
State data quality improvement is a priority to FMCSA and supports the data-driven Compliance, Safety, Accountability (CSA) program. Data-driven safety systems are vital to informing decisions that improve the safety of our nation′s roads – their effectiveness depends on complete and accurate crash and inspection reporting and continual system improvements to focus resources to further reduce crashes.

Check this Continuous Improvement page regularly for previews of changes to the State Safety Data Quality (SSDQ) evaluation. Right now, no SSDQ changes are being previewed.
