CM is defined as the activity of concerned citizens who attend and monitor court sessions of drivers charged with DSI and related offenses. The monitor's primary goal is to promote the strict enforcement of DWI laws. Although court monitors do not intervene in the adjudication process, they generally make their presence known to all parties involved in the adjudication. NPBL's are State laws designed to eliminate plea bargaining to a lesser charge once a driver is originally charged with DWI. Studies of CM in New York, Tennessee, Nebraska, and Maine indicate that such monitoring can minimize the number of dropped or reduced charges. Once an individual is charged with a DWI offense, CM can increase the likelihood of conviction. When DWI offenders are stratified by blood alcohol concentration (BAC), the impact of monitoring appears to be primarily on the conviction of drivers with low or legally marginal BAC levels and drivers who refuse the test. The effectiveness of NPBL's has not been empirically demonstrated, although citizen groups support them. The few studies that have evaluated such laws indicate that they are effective in actually reducing plea bargaining. The impact of both CM and NPBL's on the more critical measures of driver behavior and alcohol-related accidents remains to be demonstrated. Recommendations to make CM and NPBL's more effective are offered. 22 references, 2 tables, and 2 figures
