Flashing beacons attached to warning or regulatory signs are not considered traffic control signals (see of the

Texas Manual on Uniform Traffic Control Devices

(TMUTCD), Chapter 4L).

The installation of flashing beacons attached to signs does not require an authorization form; however, when mounted overhead, an authorization form should be kept on file at the district office and a copy sent to the Texas Department of Transportation (TxDOT) Traffic

Safety

Division (TRF).
