Scholars have devoted significant attention to measuring the degree to which a driver’s personal characteristics affect police decisions to stop and sanction motorists. Following the pattern of research on gender and enforcement practices more broadly, traffic stop studies show that female drivers are less likely to receive formal sanctions such as a citation following routine traffic stops. Despite the consistency of these findings across places and times, we know little about the conditions under which female traffic violators are granted leniency. This article extends research on the effect of driver and stop characteristics on gender disparities in traffic enforcement decisions by examining 149,888 stops from across 37 communities in Rhode Island with different local needs and variation in police organizational culture and structure. The findings confirm that although women are less likely to be cited than men, community-level variation in police agency culture and structure, particularly the proportion of female officers in an agency, moderates the effect of driver sex on stop outcomes.
