(b) Authorization.  Before local authorities designate any highway as a through highway or stop intersection which will intersect or affect a State-designated highway, approval of such designation shall first be obtained from the Department of Transportation.  Approval to Install R1-1 signs in work areas shall not require the approval of the Department or local authorities when the conditions stipulated in the Department's Temporary Traffic Control Guidelines are satisfied.

(c) Size.  The standard size R1-1 sign shall be 30 inches x 30 inches for single lane conventional highways and 36 inches x 36 inches for multi-lane conventional highways.  The 24 inches x 24 inches size shall only be used for alleys with restrictive physical conditions and vehicle usage that prohibits the installation of the standard size R1-1.  A sign that is mounted back-to-back with a R1-1 sign should stay within the edges of the R1-1.  If necessary, the size of the R1-1 sign should be increased so that any other sign installed back-to-back with it remains within the edges of the R1-1 sign.
