Quick question for all of you who see these blue signs at night. I have not noticed the lettering on these signs as being reflective, like the lettering on street signs. It is a MUTCD guideline that the lettering be:
"guide signs shall be retro-reflective or illuminated to show the same shape
and similar color by both day and night, unless specifically stated otherwise in the text discussion in this Manual of a particular sign or group of signs."
Anyone know?
Back to the sign colors. In Section 2A of the MUTCD, Table 2A-5. Common Uses of Sign Colors, the title of Table 2A-5 says very much -- "Common Uses" of sign colors. It is not a "requirement" for the wayfinding signs to be blue, as I read this.
This is interesting:
Section 2A.18 Mounting Height Support:
The provisions of this Section apply unless specifically stated otherwise for a particular sign elsewhere in this Manual.
Standard:
Signs installed at the side of the road in rural districts shall be at least 1.5 m (5 ft), measured from the bottom of the sign to the near edge of the pavement.
Where parking or pedestrian movements occur, the clearance to the bottom of the sign shall be at least 2.1 m (7 ft). (if the TDC is following these guidelines, it seems to me that all of the signs welcoming us into the different "towns," are set too low to the ground.)
Directional signs on freeways and expressways shall be installed with a minimum height of 2.1 m (7 ft).
If a secondary sign is mounted below another sign, the major sign shall be installed at least 2.4 m (8 ft) and the secondary sign at least 1.5 m (5 ft) above the level of the pavement edge. All route signs, warning signs, and regulatory signs on freeways and expressways shall be at least 2.1 m (7 ft) above the level of the pavement edge.
Option:
The height to the bottom of a secondary sign mounted below another sign may be 0.3 m (1 ft) less than the height specified above.
Where signs are placed 9 m (30 ft) or more from the edge of the traveled way, the height to the bottom of such signs may be 1.5 m (5 ft) above the level of the pavement edge.

and similar color by both day and night, unless specifically stated otherwise in the text discussion in this Manual of a particular sign or group of signs."
