Approximately one-third of all fatal crashes each year in the U.S. involve an alcohol-impaired driver. Prior research has shown that alcohol alters perceptions of risky behaviors such as drinking and driving. However, studies testing these perceptions typically measure them while participants are sober. A new study measuring the perceived dangerousness of driving after drinking assessed while individuals were intoxicated, and comparing these perceptions to those assessed while sober, found that sober knowledge does not necessarily translate into responsible judgment while intoxicated.
