Abstract

Across three months during 2001, Lange, Blackman, Johnson and Voas collected data from the New Jersey Turnpike to determine whether there were differences in speeding behavior grounded in race and ethnicity, while controlling for age and gender. They reported that Black drivers were more likely to speed at high rates (15 mph or more over the speed limit) in 65 mph speed zones, as were young drivers and male drivers. In the scholarly report of their research, Lange and colleagues concluded: “our research offer[s] a plausible explanation for the findings that Black drivers are represented among traffic stops at a higher rate than they are represented in the population.” The present research assesses the generalizability of the findings reported by Lange and colleagues using data reported by Massachusetts State Police officers during April and May of 2001. We also find that Black drivers, young drivers, and male drivers are more likely to speed at high rates in 65 mph speed zones. We therefore remind scholars that Lange and colleagues' findings and our own are entirely consistent with theory and research on the correlates of law violative actions. Our fundamental conclusion, however, is that more research is needed to determine whether traffic stops for Driving While Black are in small part the result of Speeding While Black.
