The goal of the Traffic Unit is to serve the community by enforcing the motor vehicle traffic laws of the Commonwealth as well as reducing the number and severity of accidents in the city. Most of the current enforcement programs are a direct response to community complaints regarding speeding and other violations. The ultimate goal is to foster greater traffic safety for motorist, bicyclist and pedestrians.

Officers in the Traffic Unit have participated in a variety of specialized trainings in order to do their jobs. Some of the specialized training includes motorcycle operation, radar/lidar operation, accident investigation, accident reconstruction, commercial vehicle enforcement and car seat installation.
