N.Y. Comp. Codes R. & Regs. tit. 17 § 2B.105
Standard:
01 The NYR7-10 Snow Emergency Route sign (see Sign Drawing SD-R12) shall be used to post designated snow emergency routes only where the statutory requirements described in Section 145-c of the New York State Vehicle and Traffic Law are in effect. The NYR7-11 Snow Emergency Route sign (see Sign Drawing SD-R12) shall be used where a supplemental regulation is established in conjunction with a snow emergency route designation.
Guidance:
02 The NYR7-10 or NYR7-11 sign should be placed, in each traffic direction, on the right side of a designated snow emergency route beyond each intersection, and at additional locations as deemed necessary or desirable. Where snow emergency parking regulations are established on the left side of a one-way roadway, snow emergency route signs should be placed on both sides of the roadway.
Option:
03 The illustrated legend on the lower part of the NYR7-11 sign may be modified, as required by the regulation, using appropriate wording in the specified letter height. The size of the NYR7-11 sign may be adjusted, where necessary to accommodate the modified legend.
