US police detain racial or ethnic minority drivers (Asian and Pacific Islander, Black, and Hispanic) more than white drivers. However, a longstanding debate remains unsettled: Does this necessarily reflect police bias? Hypothetically, if minorities were more prone to disobey speed limits and traffic laws, then their traffic stops may be warranted. To put this debate to rest, Aggarwal et al. examined rideshare data from Lyft in the state of Florida to compare minority drivers with their white counterparts. Lyft objectively measured drivers’ locations, driving speed, and location speed limits (see the Perspective by Knox and Mummolo). White and minority drivers showed no discernible differences in speeding behaviors or traffic violations. However, when both drove at identical speeds, police were still 33% more likely to issue speeding citations to minority drivers and charged 34% more expensive fines, unequivocally revealing bias. —Ekeoma Uzogara
