THE ROLE OF ALCOHOL AND HUMAN FACTORS IN ROAD ACCIDENTS

This paper deals with one aspect of the contribution to accidents made by the driver - that of fitness to drive or impairment. Impairment features are defined as alcohol, fatigue, drugs, illness or emotional distress present in the driver; the presence of alcohol being the most frequent feature. The investigation is based on data from road accidents occurring between March 1970 and February 1974 in an area of 240 sq km in southeast Berkshire. The data consisted of photographs, on-site notes and personal interviews. Assessment of the contributory factors to the accidents revealed that environmental factors contributed to 28% of the accidents, vehicle factors to 8% of the accidents, and human factors to just under 95% of the accidents. The results of the analyses made of driver impairment, alcohol in accidents, alcohol and other related factors (driving errors, age, single vehicle accidents), and interaction of alcohol with other impairment features (fatigue, drugs other than alcohol, illness and emotional distress) are presented. This paper was presented to the 5th International Conference of the International Association for Accident and Traffic Medicine and the 3rd International Conference on Drug abuse of the International Council of Alcohol and Addiction, London, 1-5 September, 1975. /TRRL/
