The use of cell phones within school zones is prohibited (unless used with a hands-free device) under of the Texas Transportation Code. A city ordinance or resolution is not required to install and enforce the CELL PHONE USE PROHIBITED (S7-1T) sign within school zones. The prohibition of the use of cell phones within a school zone can only be enforced if the CELL PHONE USE PROHIBITED (S7-1T) sign is installed below the ground-mounted school speed limit sign (S5-1) or beside the overhead school speed limit sign (S6-1T). See of the

Texas Manual on Uniform Traffic Control Devices

(TMUTCD).

TXDOT will pay for the cost and installation of these signs for on-system highways within a city with a population of 50,000 or less or outside incorporated areas. All school zones within the incorporated limits of a municipality with a population of 50,000 or more or along off-system roadways will be installed and maintained by local government forces.
