The Texas Manual on Uniform Traffic Control Devices (TMUTCD)
Title 23 Code of Federal Regulations (C.F.R.),
, defines the National Manual on Uniform Traffic Control Devices and the authority of states to adopt their own manual.
of the Texas Transportation Code requires TxDOT to adopt a manual and specifications for a uniform system of traffic control devices for use on streets, roads, and highways within the State. The uniform system must correlate with, and so far as possible, conform to the current system approved by the Federal Highway Administration (FHWA) and set forth in the national (MUTCD). The (TMUTCD) basically follows the national MUTCD, except where the national standards conflict with State law or where modifications are necessary to more closely fit Texas conditions. The latest edition of the TMUTCD was adopted by Texas Transportation Commission minute order, as referenced in Title 43,
of the Texas Administrative Code (TAC).
TxDOT’s Traffic Operations Division (TRF) is responsible for publishing and updating the TMUTCD.
