Emergency Communications Districts - As enacted, authorizes a motor vehicle operated by an emergency communications district that is marked as a mobile command vehicle or mobile communications vehicle to display flashing red or white lights or a combination of flashing red and white lights. - Amends TCA Title 55, Chapter 9, Part 4.

SB 1374 allows emergency communications districts in Tennessee to use flashing red, white, or combined red-and-white lights on vehicles marked as mobile command or mobile communications vehicles. This amendment to Tennessee’s traffic code (TCA Title 55, Chapter 9) specifically permits these specialized vehicles to display such lights while operating. The change directly affects emergency communications districts that operate these mobile units for coordination during incidents. It does not alter existing lighting rules for standard emergency vehicles like police or ambulances. The bill became law on April 4, 2025, after passing through committee reviews.
