What is the urban interstate speed limit in congested areas of Tennessee?

In congested areas of Tennessee, the urban interstate speed limit is set at 55 miles per hour. This limit is established to enhance safety in areas where there is a higher concentration of vehicle traffic, which can lead to increased risk of accidents. Lower speed limits in urban settings help to accommodate the frequent stopping and starting of vehicles, ensure better traffic flow, and reduce the likelihood of collisions. It is essential for drivers to adhere to this speed limit, as it reflects both traffic conditions and the need for caution in densely populated regions.
