Blood Alcohol Testing in Older Drivers

Older Drivers have been reported to be less likely than other drivers to be involved in alcohol related crashes. However, the literature regarding older adults' alcohol consumption prior to driving is limited, with some indication of drinking and driving among older adults. Better understanding the effects of even low levels of alcohol on older drivers' safety would be useful in developing countermeasures to enhance older driver safety. The goal of this study is to collect blood alcohol levels in drivers age 65 and older who receive hospital treatment for crash injuries. Researchers will analyze blood alcohol levels in older adults treated for crash injuries to determine the proportion of older crash victims who had any level of alcohol before the crash and the average blood alcohol content (BAC) level among those with levels of .01 or higher. The study will examine the ratio of at-fault to not at-fault crashes among those with levels of .01 or above as compared to those without measureable levels of blood alcohol.
