| Abstract | The purpose of this study was to determine the effects of special drinking driving sanctions aimed at youthful drivers under the age of 21 years. This purpose was accomplished by focusing on a Maryland law which restricts driving by those under 21 to a blood. alcohol concentration (BAC) less than 0.02% rather' than the 0.10% prevailing limit for older drivers. The specific objectives were to: 1) evaluate the impact of adoption of the sanction; 2) mount a public information and education (PI&E) campaign in selected` counties to attempt to potentiate the effects of the sanction; and 3) evaluate any added benefit of the, PI&E. Crash data were used statewide and in six experimental counties. The unit of analysis was accident-involved drivers under 21 years of age judged "had been drinking" (HBD) on the police accident report. Box-Jenkins time series analysis of this measure indicated a significant step reduction in crash-involved drivers under 21 judged HBD coincident with'adoption of the sanction and an additional significant step reduction in the experimental counties after application of the PI&E. Only the reduction coincident with the sanction adoption was detected in two comparison counties. Survey data in the experimental and comparison counties confirmed that knowledge of the sanction among youth increased significantly after exposure to the PI&E at the experimental sites but not at the comparisons. It was concluded that this special sanction for youth was effective and this effectiveness was significantly potentiated by a public service information program which emphasized the possible penalties for violation of the regulation. |
