Under these projects, a special management office was established to ensure an integrated systems approach to the problem of drunk driving that would provide resources for handling driving while intoxicated (DWI) offenders, provide public information, and developing methods for identifying problem drinkers and referring them to appropriate treatment agencies. Programs were operational from 2 to 5 years at a cost of $88 million. Overall, projects were successful in meeting their goals. Police were generally able to double or triple the number of DWI arrests. Courts developed a variety of procedures for screening problem drinkers and for efficient and rapid case processing. About 250,000 DWI offenders, of whom two-thirds were problem drinkers, were referred to education or treatment programs. Mass media programs were developed that were effective in increasing support for ASAP activities. Additional studies indicated that significant reductions occurred in both the number of high-blood-alcohol-content drivers identified at roadchecks and in the number of fatal nighttime crashes following program implementation. 3 figures and 4 tables.
