Samenvatting
A motorcycle simulator was used to assess operating performance of 14 experienced motorcyclists with varying breath alcohol concentrations. Riding error scores in three defensive and evasive maneuvres plus distance traveled in a standard time period were documented at baseline and at predetermined intervals following controlled alcohol consumption. The results are discussed. Since the present definition of the legal limit of intoxication for motorcyclists is based on automobile studies, noted increases in reaction time and performance errors support the hypothesis that "legal alcohol levels" should be lowered for motorcycle operators.
