N.Y. Comp. Codes R. & Regs. tit. 17 § 2D.29
INSERT the following paragraphs:
Guidance:
05A When a highway carries two or more routes, the route sign combinations in the assemblies should be arranged to present a symmetrical and balanced appearance to enable motorists to readily identify the route they desire to follow. Each combination should stand out as a separate unit.
05B Route sign combinations in Junction, Advance Route Turn, and Directional assemblies should preferably be mounted side by side rather than one above the other. However, there should generally be no more than three route sign combinations in the same horizontal row. Confirming and Reassurance assemblies should preferably display route sign combinations one above the other rather than side by side.
Option:
08A Junction, Advance Route Turn and Directional assemblies may be installed overhead on the approaches to intersections (see Section 2A.17 ).
Support:
09A Figure 2D-101 shows typical types of Route Sign assemblies.
