N.Y. General Municipal Law § 125-a: Posting signs on dead-end roads

§ 125-a. Posting signs on dead-end roads. It shall be the duty of

every municipal corporation and person charged with the duty of

maintaining any street or other roadway whenever such street or other

roadway terminates in a dead end or at the embankment of a river, lake,

canal, reservoir, stream or other body of water, to post and keep posted

a sign readily visible by day and night. Such signs shall be installed

in accordance with the state manual of uniform traffic control devices

and shall be illuminated from one-half hour after sunset to one-half

hour before sunrise. Where either the background or letters of the sign

are of reflecting material so that such sign is readily visible at night

when motor vehicle headlight rays fall upon the sign and it is placed in

such position that the headlight rays of approaching vehicles will

strike it, no additional illumination shall be necessary.
