Street Name Signs

High-performance street signs contribute to a safer community.

• Legible, more visible street signs help drivers navigate more safely and easily, helping to reduce

potential crashes and improve traffic flow.

• Federal Highway Administration (FHWA) estimates indicate every $1.00 spent on sign improvement

saves as much as $22.40 in accident costs.¹

• Streets clearly marked with reflective street name signs help emergency response vehicles

reach their destination more quickly

Since the adoption of the 2009 National MUTCD, the lettering sizes and allowable colors for street name and some guide signs have changed.

• Lettering needs to be a mix of upper and lower-case letters. 
• First letter of each name or abbreviation shall be upper-case and the rest of the lettering in the name or abbreviation shall be lower-case.
• Lettering height should be at least six inches (6”). For local roads with speed limits of 30 mph or less, the lettering height may be reduced to four (4”) inches.
• Street name signs have a white legend on a green background.
• Other acceptable color combinations are a white legend on a blue or brown background, or a black legend on a white background.
