The National Highway Traffic Safety Administration (NHTSA) estimated that in 2003, about 36 percent of motorcycle operators involved in fatal crashes had BAC of 0.01 or higher. Clearly, enforcing impaired driving laws is a key to reducing the number of alcohol-related motorcyclist fatalities. But which clues should be used to detect impaired motorcyclists. NHTSA sponsored research to develop a set of behavioral cues to be used by law enforcement personnel to detect motorcyclists who are operating their vehicles while intoxicated. The researchers began by interviewing experienced patrol officers from across the country to determine what behavioral cues have been used to detect impaired motorcyclists. A few, primarily motorcycle officers, suggested cues that reflected considerable understanding of the mental and physical requirements of riding a motorcycle. Others believed the cues to be identical to those used to detect impaired drivers. But some officers, even those with many years of experience, reported they believe there are no cues that can be used to distinguish DWI from unimpaired motorcycle operation. In addition to interviewing law enforcement personnel, the research team developed a database of 1,000 motorcycle DWI arrest reports. The research team focused on officers narratives and motorcyclists behaviors that motivated the stops, and correlated those behaviors with blood alcohol concentrations (BAC). Analysis of the interviews and arrest report data resulted in an inventory of about 100 cues that have been observed by officers in relation to impaired operation of motorcycles. Fourteen cues were identified that best discriminate between DWI and unimpaired motorcycle operation. |
