This study explored people's perceptions of risk associated with drinking alcoholic beverages before driving. Subjects rated the level of hazardousness of driving after consuming two, four, or six drinks of beer, wine, or hard liquor during a one, two, or three hour time frame. Differences in perceived hazard were found between the types of beverage consumed. Specifically, hard liquor was perceived as being more hazardous than both beer and wine. As expected, perceived hazard levels increased as the number of beverages consumed increased, and, as the time period increased, the average hazard rating decreased. For example, four drinks in three hours were perceived as less hazardous than four drinks in one or two hours. Generally, people perceive two drinks to result in a less than moderate driving hazard when consumed in a short time frame, while four or more drinks are perceived to be a hazardous level of consumption for driving.
