Previous study results were confirmed showing that high income and education levels had a protective influence on alcohol-related fatal motor vehicle crashes. Also confirmed was that language proficiency/acculturation tended to increase the vulnerability of Hispanic women to alcohol-related fatalities. Prevention policies may be required that take into account existent variations in acculturation, income, and education among racial/ethnic groups and subgroups in order to reduce alcohol-related traffic fatalities. In contrast to age and gender, the role of race/ethnicity in alcohol-related fatal motor vehicle crashes has received relatively little attention. This study investigated the simultaneous role of language-acculturation among Hispanics, income, and education on alcohol-related fatal motor vehicle crashes. The acculturation analysis was limited to California and its neighboring States--Arizona, New Mexico, and Texas. These States share a border with Mexico and have a Hispanic population of similar origin. The role of income, education, and race/ethnicity was studied for the United States as a whole, the four-State group, and separately for California. Tables, references
