(a) Generally, signs shall be placed in
				positions where they will convey their messages most effectively and provide
				adequate driver response time.
(b)
				All advance warning signs shall inoicate the character of the work being done
				and, where possible, the distance from the sign to the work site. Advance
				warning signs shall be positioned as follows:
(1) Where the speed limit exceeds forty-five
				miles per hour, an advance warning sign shall be placed, on each approach
				affected by the work, approximately two thousand four hundred feet in advance
				of the work site. Additional advance warning signs shall be placed
				approximately one thousand five hundred feet in advance of the work site and
				thereafter at approximately five hundred-foot intervals in advance of the work
				site.
(2) Where the speed limit is
				forty miles per hour or forty-five miles per hours, an advance warning sign
				shall be placed, on each approach affected by the work, approximately one
				thousand five hundred feet in advance of the work site. Additional advance
				warning signs shall be placed at five hundred-foot intervals between the first
				advance warning sign and the work site.
(3) Where the speed limit is thirty miles per
				hour or thirty-five miles per hour, except as provided in paragraphs (4) and
				(5) of this subsection, an advance warning sign shall be placed, on each
				approach affected by the work, approximately seven hundred fifty feet in

				high level warning devices may be placed between the first high level warning
				device and the work site. The flags on a device shall be at least eighteen
				inches in length by eighteen inches in width, and shall be red or another color
				approved by the director. The flasher on a device shall be amber in color. The
				flags or flasher shall be at least five feet above the pavement
				level.

				thirty miles per hour or thirty-five miles per hour and the work being
				performed is engineering survey, service, maintenance, or inspection work which
				is being performed during off-peak hours, does not interfere with traffic
				movement, and lasts no longer than three hours, a single high level warning
				device described in paragraph (4) of this sub-section may be used in lieu of
				the advance warning signs.-The device shall be placed, on each approach

				where placement of the advance warning sign may not be feasible or may cause
				confusion.

				limit is twenty-five miles per hour or less and the work being performed is
				engineering survey, service, maintenance, or inspection work which is being
				performed during off-peak hours, does not interfere with traffic movement, and
				lasts no longer than three hours, a high level warning device as described in
				paragraph (4) of this subsection may be used in lieu of the advance warning
				sign. It shall be placed, on each approach affected by the work, approximately
