This study investigated the effect of body-worn cameras (BWCs) on citizens’ satisfaction with the encounter and citizens’ general perceptions of the police during traffic stops. A post-test-only two-group quasi-randomized experimental design was implemented. Drivers in the experimental group encountered the traffic police officers wearing BWCs and were notified that the encounter was being filmed, whereas those in the control group experienced business-as-usual traffic stops. A survey was administered to drivers after completion of the traffic stop. In total, 624 out of 860 stopped drivers (325 in the control group and 299 in the experimental group) participated in the survey. Both bivariate and multivariate analyses showed that BWCs increased significantly citizens’ satisfaction with the encounter and citizens’ general perceptions of the police.
