Traffic Bureau


Motors and Traffic consists of officers riding motorcycles. The use of motorcycles allow officers better accessibility to traffic-related problems.

It is our mission to create safe roadways for all. This is accomplished through education, addressing matters related to engineering, and enforcement.

We also allow the public to use the department’s radar trailer. The radar trailer allows us to better understand traffic-related problems in a specific area and serves as an educational tool for commuters.
