The Detection of DWI Motorcyclists

The National Highway Traffic Safety Administration (NHTSA) sponsored research to develop a set of behavioral cues that can be used by law enforcement personnel to accurately detect motorcyclists who are operating their vehicles while intoxicated. Fourteen cues were identified. Seven of these cues are considered excellent cues with a 50% or greater probability of detecting the alcohol impaired motorcyclist. The other seven cues are considered good cues with a 30% to 50% probability of detecting the impaired motorcyclist. This brochure describes and illustrates each of these cues. It should be helpful to law enforcement officers in: detecting impaired motorcyclists; articulating observed behaviors on arrest reports; and supporting an officer's expert testimony.
