This article describes the evaluation of a 4-1/2-month multimedia traffic-safety campaign that targeted young drivers in northeastern Tennessee. Discussion groups with teenagers provided the basis for public-service announcements (TV, radio, and billboard), which were developed specifically for this intervention. To determine the impact on crash frequencies among drivers 16-19 years old, baseline, intervention, and follow-up crash data were obtained from statistics maintained by the state. A time-series analysis of these data indicated that during the intervention period, there was a 21.6% decrease in crashes for which 16-19-year-old drivers were at fault, whereas a control location in southeastern Tennessee exhibited no significant change.
