For Years, Every U-Turn in Mt. Juliet Was Against the Rules. That Just Changed.
Here is something almost nobody in Mt. Juliet knew they were doing wrong: until Monday night, every single U-turn made inside the city limits was against the local code. Not just the ones at busy intersections. Not just the ones where a sign told you no. All of them.
That quiet contradiction ended on August 24, when the Board of Commissioners gave final approval to an amendment rewriting how the city handles the maneuver. The ordinance cleared its second and final reading, and with it the city dropped a blanket prohibition that had been sitting on the books while drivers went right on swinging around in the medians of Lebanon Road and Mt. Juliet Road, as they always had.
The new rule is the one most Tennessee drivers already assumed applied. A U-turn is legal anywhere in Mt. Juliet unless a posted sign says otherwise — and provided the turn can actually be made safely, with the room and the visibility to do it. That brings the city into line with state law, which has long treated the U-turn as permitted by default and restricted by signage.
What happens next is the part worth watching
Repealing the old ban was only half of what the commission did. The same ordinance hands the city engineer and the public works director the authority to designate specific locations where U-turns are prohibited, and to put up signs saying so. Those signs can also carry time-of-day restrictions, which means an intersection could be open to U-turns at ten in the morning and closed to them at five in the afternoon.
So drivers should expect black-and-white “No U-Turn” signs to start appearing at selected intersections around town. Where one goes up, it carries real weight — turning against a posted sign can bring a penalty. The city has not announced which intersections are first in line, and no timeline for installation has been made public.
Why a small traffic rule says something about a growing city
Mt. Juliet has not been a quiet crossroads for a long time. The city incorporated in 1972, and for its first few decades it was the kind of place where a blanket rule about turning around simply never came up. Then the growth arrived. The population stood at 23,671 in the 2010 census. By 2020 it was 39,289 — a jump of roughly two-thirds in ten years. Recent estimates put it above 45,000. For years the city has laid claim to being the fastest-growing in Tennessee, and the arithmetic has generally backed it up.
What that growth built was a particular kind of road. Sitting about 17 miles east of downtown Nashville with two Interstate 40 exits of its own, the City Between the Lakes filled in along two commercial spines: U.S. 70, which everyone calls Lebanon Road, and State Route 171, which everyone calls Mt. Juliet Road. Both are wide, both are divided by long medians, and both are lined with the shopping centers and restaurant pads that a suburb of 45,000 people generates.
On roads built that way, the U-turn is not a stunt. It is the ordinary way a driver corrects a missed entrance or reaches a business sitting on the opposite side of a median that runs for a quarter mile. A citywide ban on the books was never going to survive contact with how the city was actually laid out. Monday's vote acknowledged that, then handed engineers a scalpel to use where a specific intersection genuinely needs one.
For now, nothing is required of drivers except attention. The turn you have probably been making for years is finally, formally legal. Watch for the signs that will decide where it stops being so.
The U-turn amendment was taken up at the same August 24 meeting that drew three scheduled public hearings on new residential development. Growth is also behind a separate question heading to voters this fall on who pays for the roads and infrastructure that come with it.
