Speed Limits; General Signage Guidance

Many areas might have sections of a road in which a lower speed is recommended. Examples of this include curves, sharp turns, complex four way intersections, industrial zones etc. These advisories on yellow signs, usually show what type of advisory it is.

Figure 1 shows a legal DOT enforceable speed limit. These are usually on white signs and are the only things to be added to the road for it's speed.

Figure 1

Figure 2 shows a common advisory sign. This would be located before a sharp curve and can be accompanied by the sharp curve arrow instead. This type of speed limit is to be ignored for the purposes of adding speed limits.

Figure 2

The US guidelines for speed limits follow what is posted on the legal speed limit signs. (White or otherwise noted) Advisory signage is to be ignored for the purposes of inputting speed limits. School zones are also to be ignored, as they are only active for short amounts of time throughout the day.
