Proposed truck route signing should be adequate and in compliance with current signing practice. All signs required must conform to current standards as set out in the

Texas Manual on Uniform Traffic Control Devices

(TMUTCD) with regard to shape, size, color, letter size and style, mounting, location, etc.

The large and small advance TRUCK ROUTE sign assemblies may be used for additional emphasis of an existing or proposed truck route. See Figure 5-4 for an example of large advance truck route sign assembly.

Advance truck route sign assemblies are typically used to denote a truck route. See Figure 5-5 for an example of small advance truck route sign assembly.

The city must submit to the district office a suitable sign design detail drawn to scale showing the proposed sign shape, color, size, text and locations.

TxDOT installs all signs on expressways and freeways. Depending on the provisions of the municipal maintenance agreement, a city may be allowed to install signs on a conventional highway within its corporate limits. TxDOT installs signs on highways outside the corporate limits of a city as necessary to achieve a continuous connecting route.

The city bears all costs for signs and sign installations.

The TRUCK (M4-4) panel sign is not used in conjunction with an interstate route marker.

After the city passes the ordinance establishing the truck route, the district should provide a map that clearly defines the route to TRF.
