What is the speed limit in congested urban or metropolitan areas of Tennessee interstates?

In congested urban or metropolitan areas of Tennessee interstates, the speed limit is set at 55 miles per hour. This lower speed limit is designed to enhance safety in areas where traffic is typically heavier, with more intersections, pedestrians, and various road conditions contributing to potential hazards. By maintaining a reduced speed limit in these zones, it helps to decrease the likelihood of accidents and allows drivers more time to react to sudden changes in traffic patterns. This regulation aligns with broader traffic management practices aimed at ensuring safe travel in densely populated areas.
