Major findings from this study of alcohol-impaired driving patterns and ethnic drinking practices among major racial and ethnic groups include: alcohol abstention is high among Asians, African-Americans, and Hispanics, and low among Whites and Native Americans; rates of binge drinking are highest among Native Americans, Hispanics, and Whites; large variations in drinking patterns exist within various subgroups of different ethnic groups; Whites and Native Americans are among those most at risk for alcohol-impaired driving, while Asians are at the lowest risk; rates of impaired driving for Hispanics and African-Americans show an overrepresentation in arrest and crash data, but an underrepresentation in self-report data from national surveys; and factors affecting impaired driving rates among the various racial and ethnic groups include age, gender, marital status, socioeconomic status, and rural versus urban settings. This report from the U.S. Department of Transportation, National Highway Traffic Safety Administration, examines what is known about alcohol-impaired driving patterns among major racial and ethnic groups, as well as differences in ethnic drinking patterns. Data for this report were obtained from an extensive review of literature that examined differences in drinking and driving patterns among major racial and ethnic groups. The findings indicate that substantial differences exist in drinking and alcohol-impaired driving patterns across different racial and ethnic groups. A list of culturally competent prevention strategies is discussed. Tables, figures, and references
