Drinking and driving among high-risk young Mexican-American men.

Determinants of driving under the influence of alcohol (DUI) were explored among a sample of relatively young Mexican-American males with limited income and education, high levels of alcohol consumption, and regular vehicle use. Data were collected using questionnaires (N=104) and focus groups (N=27), including a focus group with wives and girlfriends (N=4). Four mechanisms that may contribute to the high rate of DUI behavior in this population were identified: (1) a subculture of permissiveness toward drinking and driving for men, (2) heavy drinking, promoted by machismo and a propensity to measure masculinity with alcohol intake, (3) inadequate knowledge of DUI statutes and inadequate understanding of the relationships between BAC, impairment, and crash risk, and (4) for undocumented drivers, lack of accountability in case of an alcohol-related incident.
