ALCOHOL IMPAIRMENT OF PERFORMANCE ON STEERING AND DISCRETE TASKS IN A DRIVING SIMULATOR. PART I. EFFECT OF TASK LOADING. PART II MODERATE VS. HEAVY DRINKERS

A simplified laboratory simulator was developed to test two types of tasks used in driving on the open road: a continuous 'steering task' to regulate against gust induced disturbances and an intermittent 'discrete response task' requiring detection, scanning, recognition, and motor response typical of, for example, horn or brake operations. The development of the simulator, the behavioral and performance measures, and some basic effects of blood alcohol concentrations of up to 0.11 BAC on a mixed group of 18 moderate and heavy drinkers is given. The differences between the driving and discrete tasks both alone and combined, are studied. The objective of the program, was to examine the differences in alcohol impairment of driving performance between 'moderate' and 'heavy' drinkers.
