Road Contributing Circumstances is a field that was completed appropriately for almost 95 percent of the reports reviewed, with very little variation between the two submittal types for local police. The majority of the time, if the field was considered unacceptable, it was left empty. Please note that there is no data for State Police reports, as this is a new crash report field and was not being used by State Police during the audit period.
