Replying to @photomartint
@volvovtl MUTCD is the Manual on Uniform Traffic Control Devices. It describes the application of road signs, signals, etc. in the US.
Symbols are what you make of them! Except for traffic symbols. A stop sign is always a stop sign.

The number of Specific Service signs before an interchange, regardless of the number of service types displayed, shall be no more than four.
Roundabout in Clearwater Bch, FL incorrectly marked like this http://bit.ly/hqjHQ9 should probably look like this http://bit.ly/dUDv8a
Continuous concentric lane lines shall not be used within the circulatory roadway of roundabouts.
Dad recently stayed in Clearwater Bch, FL. Says the roundabout there had many accidents. I say probably because it doesn't adhere to @MUTCD
Over-crossing structures may be used to support overhead signs.
The sign lettering for names of places, streets, and highways shall be composed of lower-case letters with initial upper-case letters.
All sign lettering shall be in upper-case letters, unless otherwise provided in this Manual for a particular sign or type of message.
When an Interstate route is displayed in text form instead of using the route shield, a hyphen should be used for clarity, such as "I-50."
