Advisory Speed Sign Posting
The W13-1 ADVISORY SPEED sign may be used in conjunction with any warning sign to indicate the maximum safe speed for passenger cars around a curve or through a hazardous location. It must not be used in conjunction with any sign other than a warning sign, nor shall it be used alone.
The W13-1 sign shall always be mounted on the same post with and immediately below the warning sign to which it applies.
Figure 5-1 shows typical warning and advisory speed signing applications.
