In 1982, a set of strict new countermeasures against drinking-driving went into effect in California. Interrupted time series analysis is used to investigate the effect that these countermeasures have had on fatal accident levels during the first postintervention year. The results do not indicate that a deterrent impact occurred among those accidents. Supplementary analyses of injury accidents during the first postintervention year and of fatality accidents during the first nine months of 1983 add important qualifications to this basic finding.
