The Traffic Engineering Office provides guidance and direction to improve highway safety and traffic operation along Tennessee’s roadways. The office participates with other agencies in the coordination of educational activities, enforcement and regulatory measures, and engineering solutions to promote and emphasize roadway safety and operational efficiency.

An important area of operation includes oversight of the uniform use and application of traffic control devices, such as traffic signals and roadway signing and marking. Other areas of emphasis include management of speed limits and parking areas along state roadways outside city limits.
