Impact of court monitoring on the adjudication of driving while intoxicated (DWI).

Court monitoring of driving while intoxicated (DWI) cases is a labor-intensive effort conducted by over 300 concerned citizen groups across the United States. The present study assessed the impact of court monitoring by analyzing the difference in court dispositions (guilty, not guilty, and dismissed) and case outcomes (jail, fine, and license suspension) between monitored cases and non-monitored cases. The data base for this study consisted of all 9,137 DWI arrests made in the state of Maine in one calendar year. The results demonstrated that court monitoring is an effective tool in affecting the adjudication process. In the presence of court monitors the conviction rates of DWI offenders were higher and their case dismissal rates were lower than those of drivers not court-monitored. Furthermore, once convicted, the likelihood of a jail sentence was higher and the length of the jail sentence was longer for court-monitored DWI drivers than for non-monitored drivers. Monitoring impact was most pronounced for first-time offenders with BAC levels of .10-.11, and those refusing the BAC test.
