NHTSA’s Visual Cues For Impairment Of Motorcyclists

In the National Highway Traffic Safety Administration’s DWI Detection and Standardized Field Sobriety Testing Program, police officers are trained in “DWI Detection Phases.” The phases are vehicle in motion (phase one), personal contact (phase two), and pre-arrest screening (phase three). The authors address phase one and the cues that apply to the vehicle in motion when that vehicle is a motorcycle. They examine how the cues stack up to analyses of real-world riding techniques.
