Procedural justice has been found to impact citizens' perceptions on legitimacy. Using data from the Police-Public Contact Survey (PPCS) in 2011, individuals were asked about their encounters with police officers within the previous year. This study aimed to identify the potential influence procedural justice had on the respondents' perception of the legitimacy specifically during traffic stops. Three components in the procedural justice model (individuals feeling as though they were being treated fairly, police officers were perceived to be respectful during the interaction, and individuals feeling that they had voice during the encounter) were used in this study. While race and ethnicity were predicted to influence respondents' perceptions, only ethnicity was found to make a difference where Hispanics were less likely than non-Hispanics to perceive the traffic stop as legitimate. Additionally, individuals in the higher earning income group were more likely to identify the traffic stop as legitimate in comparison to the other two income groups. The components of procedural justice that were found to influence respondents' perception of legitimacy were fairness and respect, however, individuals' voice was not found to be influential in respondents' perception. Limitations to this study and future research are suggested. Policy implications such as more effective communication and cultural competency training are discussed.
