Emergency crossovers on Tennessee interstates are legally permitted for use by:

Drivers making U-turns.
Emergency vehicles and highway maintenance crews.
Drivers who missed their exit.
All of the above.
Explanation

Tennessee law strictly limits interstate emergency crossover use to emergency responders (police, fire, EMS) and authorized highway maintenance vehicles only. These crossovers are never legal for public use - whether for recovering from a missed exit, making U-turns, or any other personal maneuver. If you miss your exit, continue to the next designated exit rather than attempting to turn around. This is extremely dangerous and illegal.
