Officers within the Traffic Unit work to ensure that Roanoke County's streets are safe for everyone. Crash investigations and reconstruction are a major part of understanding how crash fatalities occur and a key part in preventing future injuries and deaths.

The unit also offers Driving Safety at local high schools, targeted directly at new drivers, and presentations to local businesses, civic groups, and to the annual Citizens' Public Safety Academy. 

Along with education, the Traffic Unit works to enforce safe driving through several specialized programs such as "Operation Daily Watch" and "Road of the Day," which focus on residential and secondary roads. The unit also coordinates roadside sobriety checkpoints and seat belt surveys across Roanoke County.
