Overhead Guide Signs provide a uniform and effective system of highway signing for freeway and expressway traffic. These signs provide directions and important information to travelers who are not familiar with the route or area, providing clear instructions for orderly progress to their destinations. Signs are designed per Federal and State specifications, ensuring that they are legible to travelers approaching them and readable in time to permit proper responses.
- Long visibility distances
- Large lettering and symbols
- Short legends for quick comprehension
Proposed MUTCD Lettering Regulations
Based on older driver research, FHWA proposes to eliminate the option of all uppercase letters for names of places, streets and highways and to require that these names comprise lowercase letters with an initial uppercase letter. Mixed case sign legends for destinations have significant legibility and recognition distance benefits versus all uppercase letters.
