Black drivers were significantly more likely: to have been stopped by the police in the past year; to be stopped by the local police; to have a higher number of prior lifetime stops per year of driving; and to travel rarely on the interstate highways. White drivers were more likely to: drive more miles per year; use the interstate; fail to wear a seatbelt; fail to signal when changing lanes; roll through stop signs; run yellow lights; and use more methods to avoid speeding tickets.
