Study Finds Racial Disparities in Traffic Stops

An independent study of traffic stops in Vermont found that police officers are far more likely to pull over, search, and arrest black and Hispanic drivers, compared to white drivers, but white drivers are more likely to be found with illegal contraband.

The study, which analyzed racial disparities in traffic stops by Vermont State Police between 2010-2015, showed that black drivers were pulled over most often, followed closely by Hispanics. When stopped, black drivers were searched 4.6 times more often than white drivers, while Hispanics were searched four times more often than whites.

Despite having significantly higher odds of being searched and arrested, black and Hispanic drivers had a lower probability of being found with contraband, known as hit rate, than whites, according to the findings.

Overall, white and Asian drivers were stopped least often based on their shares of the population and were treated similarly except when it came to citations. Asian drivers received citations 48.1 percent of the time compared to 36.9 percent for whites.

“The fact that black and Hispanic drivers who were searched were significantly less likely to be carrying contraband than white drivers is evidence of inefficient policy and potential racial bias,” said study co-author Stephanie Seguino, a professor of economics at the University of Vermont, who conducted the study as public service.

“The black-white disparity in search rates has widened since 2011, which indicates a worsening of racial disparity in searches. That said, my work with the Vermont State Police suggests to me they are leaders in the state in their willingness and commitment to address this issue.”

Other states and cities report similar rates of racial discrepancies, including the Burlington Police Department based on a 2014 study by Seguino and Nancy Brooks of Cornell University, who also co-authored the current study.

Despite unsuccessful attempts in the past to curb racial disparities in traffic stops, Vermont State Police officials are committed to addressing the issue on various levels.

“Biased policing goes against the core values and mission of the Vermont State Police,” said Capt. Ingrid Jonas, director of Fair and Impartial Policing and Community Affairs for the Vermont State Police.

“From the beginning, we have recognized that racially biased policing and the perception of its practices are critical issues facing law enforcement across the nation, and in Vermont. Collecting and analyzing traffic stop race data has been one part of our efforts for many years, and we remain open to learning more about this important topic.”

The study also discovered notable racial disparities in policing by location of barracks. For example, the search rate of black drivers is six times greater than white drivers in the area of the Brattleboro and Rutland barracks compared to just two times greater in the Middlesex and Williston barracks.

“We deeply appreciate Dr. Seguino’s work and look forward to working collaboratively to make the Vermont State Police a better organization,” said Capt. Jonas. “We will continue to act with intention to ensure professionalism at all levels within our department, ensure we serve everyone with fairness and dignity, and listen to the concerns of the community.”
