Policy Guidance for Signing
The (TMUTCD) lists the following standards for memorial signs installed along a highway:
- Memorial names must not appear on directional guide signs.
- Memorial signs must not interfere with the placement of any other necessary highway signing.
- Memorial signs must not compromise the safety or efficiency of traffic flow.
Memorial signs must be reflective with a brown background and white legend. Signs will be limited to one at each end of the designated limits, typically with a sign at the beginning of the memorial highway limits in each direction, and at such intermediate sites that markers are approximately 75 miles apart.
