Abstract

Laboratory studies were reviewed of alcohol influence on three essential driver performance areas: vision, tracking, and division of attention. When examined by isolating a specific function, most visual in tracking studies failed to find an appreciable decrement due to alcohol. However, when these same visual art tracking functions were a component task within a more complex requirement for joint performance of several functions, large performance decrements occurred at low blood alcohol levels. It was concluded that alcohol affects the ability to process appreciable quantities of information. When these arrived at more than one source, simultaneously, as is typical of the requirements for driving. The conclusion was supported by additional evidence demonstrating alcohol-induced performance decrement of division of attention tasks and tasks requiring rapid processing of information. Drug dose studies demonstrated significant impairment of division of attention tasks by 0.02% BAC, with nearly all subjects exhibiting effects by 0.03%.
