Street name sign (D3-1).

Amend the fourth guidance, paragraph 07 of MUTCD Section 2D.43 to read:
In urban or suburban areas, especially where Advanced Street name signs are not used, the use of overhead Street Name signs should be considered. If overhead Street Name signs are used, the lettering should be at least 12 inch upper-case with 9 inch lower case letters where posted speeds are 40 mph or greater. For roads with posted speeds less than 40 mph, lettering should be 8 inch upper case letters with 6 inch lower case letters or greater for overhead Street Name signs. New construction should include the larger size letters for overhead signs. Internally illuminated signs may use smaller letter size.
