What is the minimum speed limit in the right lane on interstates in Tennessee?

The minimum speed limit in the right lane on interstates in Tennessee is 45 miles per hour (m.p.h.). This regulation is designed to maintain smooth traffic flow and ensure safety on high-speed roads. It helps prevent slow-moving vehicles from unnecessarily congesting the faster lanes, which can lead to hazardous driving situations.

The choice of 45 m.p.h. as the minimum speed strikes a balance that allows for efficient travel while still being manageable for a variety of vehicles. This limit serves as a guideline to help drivers make informed decisions about their speed, contributing to overall safer driving conditions on interstates. Slower speeds can create problems, especially on busy highways, where maintaining a consistent pace is crucial for preventing collisions.
