PIE focused attention on the hazards of the drinking-driver through three countermeasure activities: a mass media campaign using television, radio, and newspapers; a citizen involvement campaign which used speaking engagements, distribution of fliers, posters, and pamphlets, contacts with military and industrial groups, and breathalyzer displays; and a driver and traffic safety enrichment campaign directed to students, teachers, and administrators. Scientific evaluation of the Public Information and Education Study was accomplished through analysis of data generated by four annual household surveys and four annual voluntary roadside sureys. Analysis of the household survey data showed that PIE was effective for the general public and that it was fairly effective in increasing levels of awareness and recognition of ASAP in Anglo, Latin, and Black ethnic groups. The program met with less success in increasing levels of knowledge among the Black population and in being equally effective in reaching youth and adult populations. Data from the roadside surveys indicate that PIE was not effective in reaching drunk drivers. Although PIE did as well or better than planned, much remains to be done. The data analyses are presented in 22 tables.
