What if driver ‘failed to use care’?
Select ‘other’ as it was a contributing action, not specified.
Does the order matter i.e. more related to the cause?
- If Driver Contributing Code lists ‘distracted’, then the value for Driver Distracted By should be something other than ‘not distracted’.
- If Driver Contributing Code indicates a citable offense, all issued citations should be listed under Citation Number and Violation 1-4 (Chapter/Section/Subsection).

Data Quality Audit Results
|Local Police (electronic)||568||95.1%||14||2.3%||2||0.3%||13||2.2%|
|Local Police (paper)||554||90.2%||33||5.4%||3||0.5%||24||3.9%|

The Driver Contributing Code field was considered acceptable in 92 percent of the reports reviewed. In reports that had inconsistencies, the greatest percentage came from paper submissions by local police. Another issue with this field was leaving it empty, which was the case for more than 4 percent of reports reviewed, and the biggest issue for State Police. Compared to the 2008 audit, the percentage of acceptable reports for this field has gone up by 2 percent. Auditors expressed concern about the difference between ‘inattention’ and ‘distracted’. Auditors also commented that police departments had varying informal policies regarding their use of this field and its relationship to the cause of the crash and citations issued. Some departments indicated a citation needed to be written for whatever driver contributing factor was described here. Therefore, the field was only completed if the officer was certain of the driver contributing factor and was willing to issue a citation.
