In 2016, Minnesota deployed an officer-centric electronic crash reporting system to all Minnesota law enforcement officers. Usability testing of the new system upon deployment suggested high user satisfaction but could not immediately determine the extent of the crash data improvement. This study employed a mixed-methods approach to conduct a series of qualitative analyses of crash data records collected by the legacy crash reporting system and the new MNCrash reporting system. The analyses leveraged officer reported narratives and data business rules to determine that crash data quality improved through multiple metrics. Improvements with the new system included a decrease in mismatching data and erroneous data entries compared to 2015.
