It is unlawful for any person to drive a vehicle less than what speed in the leftmost lane of any Interstate highway?

Driving a vehicle in the leftmost lane of an Interstate highway requires certain speed regulations to ensure safety and efficient traffic flow. The requirement to maintain a minimum speed in that lane is primarily to prevent slower vehicles from impeding the more rapidly moving flow of traffic, which typically uses the left lane for overtaking.

In Tennessee, the law stipulates that it is unlawful to drive slower than 55 miles per hour in the leftmost lane of any Interstate highway. This regulation is designed to reduce the risk of collisions and road rage that can occur when vehicles are traveling significantly slower than the general flow of traffic. Maintaining this minimum speed helps keep the left lane free for those who are passing or need to travel at higher speeds, contributing to overall road safety.
