EFFECTS OF SMALL DOSES OF ALCOHOL ON DRIVER PERFORMANCE IN EMERGENCY TRAFFIC SITUATIONS
The effects on driver performance of blood alcohol concentrations below 50 mg% were studied in two contexts: (1) in a critical car driving situation involving emergency braking and evasive maneuvers; and (2) in a "surprise" situation that followed the first one and featured the sudden appearance of a man-shaped obstacle blocking the road-way. The results indicate the detrimental effects of alcohol at a total BAC-average of 42 mg%. In the braking and maneuvring task, drivers under the infleunce of alcohol hit significantly more pylons and took significantly longer distances to stop. There were also a strong tendency for alcohol to impair performance in the surprise situation. Under the influence of alcohol five drivers out of ten collided with the obstacle; this was the case for only one driver out of ten in the control (non-alcohol) condition.
