Black drivers were more likely to be pulled over by police than white drivers, according to a 2020 study of approximately 95 million traffic stops by 21 state police agencies and 35 municipal police departments between 2011 and 2018. The study by a team of 11 academics also found the disparity shrinks at night, when a motorist's race is harder to identify, suggesting race may play a role in who is stopped.
