67 Pa. Code § 167.3 - Types of warning devices
One of the following combinations of warning devices shall be carried on those vehicles, specified in § 167.2 (relating to scope and application), and equipped before January 1, 1974:
(1) Three liquid burning emergency flares
which satisfy the requirements of SAE Standard J597, "Liquid Burning Emergency
Flares", and three fusees and two red flags.
(2) Three electric emergency lanterns which
satisfy the requirements of SAE Standard J596, "Electric Emergency Lanterns",
and two red flags.
(3) Three red
emergency reflectors and two red flags. A red emergency reflector shall conform
to the following requirements:
(i)
Reflecting elements required. A reflector shall be composed of
at least two reflecting elements or surfaces on each side, front and back. The
reflecting elements, front and back, shall be approximately parallel.
(ii)
Reflecting elements to be Class
A. A reflecting element or surface shall meet the requirement for a
red Class A reflector contained in the SAE Recommended Practice "Reflex
Reflectors." The aggregate candlepower output of all the reflecting elements or
surface in one direction shall not be less than 12 when tested in a
perpendicular position with observation at 1/3° as specified in the
Photometric Test contained in the above mentioned Recommended
Practice.
(iii)
Reflecting
surfaces, protection. If the reflector or the reflecting elements are
so designed or constructed that the reflecting surfaces would be adversely
affected by dust, soot or other foreign matter or contacts with other parts of
the reflector or its container, then the reflecting surfaces shall be
adequately sealed within the body of the reflector.
(iv)
Reflecting surfaces to be
perpendicular. A reflector shall be so constructed that, when the
reflector is properly placed, every reflecting element or surface is in a plane
perpendicular to the plane of the roadway surface. Reflectors which are
collapsible shall be provided with means for locking the reflector elements or
surfaces in the required positions; such locking means shall be readily capable
of adjustment without the use of tools or special equipment.
(v)
Reflectors, mechanical
adequacy. A reflector shall be of such weight and dimensions as to
remain stationary when subjected to a 40 mile per hour wind when properly
placed on a clean, dry, paved road surface. The reflector shall be so
constructed as to withstand reasonable shocks without breakage.
(vi)
Reflectors, incorporation on
holding device. A set of reflectors and the reflecting elements or
surfaces incorporated therein shall be adequately protected by enclosure in a
box, rack or other adequate container specially designed and constructed so
that the reflectors may be readily extracted for use.
(vii)
Certification. A red
emergency reflector designed and constructed to comply with these requirements
shall be plainly marked with the certification of the manufacturer that it
complies therewith.
(4)
Three red emergency reflective triangles.
(i)
Requirements for emergency reflective triangles manufactured before
January 1, 1974. A reflector shall be a collapsible equilateral
triangle, with legs not less than 17 inches long and not less than 2 inches
wide. The front and back of the exposed leg surfaces shall be covered with red
reflective material not less than 1/2 inch in width. The reflective surface,
front and back, shall be approximately parallel. When placed in position, one
point of the triangle shall be upward. The area within the sides of the
triangle shall be open.
(ii)
Reflective material. The reflecting material covering the leg
of the equilateral triangle shall comply either with:
(A) The requirements for reflex-reflector
elements made of red methyl-methacrylate plastic material, meeting the color,
sealing, minimum candlepower, wind test, vibration test and corrosion
resistance test of section 3 and 4 of Federal Specification RR-R-1185, dated
November 17, 1966.
(B) The
requirements for red reflective sheeting of Federal Specification L-S-300,
dated September 7, 1965, except that the aggregate candlepower of the assembled
triangle, in one direction, shall be not less than eight when measured at
.2° divergence angle and -4° incidence angle, and not less than 80% of
the candlepower specified for 1 square foot of material at all other angles
shown in Table II, Reflective Intensity Values, of L-S-300.
(iii)
Reflective surfaces
alignment. A reflective triangle shall be so constructed that, when
the triangle is properly placed, the reflective surfaces shall be in a plane
perpendicular to the plane of the roadway surface with a permissible tolerance
of plus or minus 10°. Reflective triangles which are collapsible shall be
provided with means for holding the reflective surfaces within the required
tolerance. The holding means shall be readily capable of adjustment without the
use of tools or special equipment.
(iv)
Reflectors mechanical
adequacy. A reflective triangle shall be of such weight and dimensions
as to remain stationary when subjected to a 40 mile per hour wind when properly
placed on a clean, dry paved road surface. The reflective triangle shall be so
constructed as to withstand reasonable shocks without breakage.
(v)
Reflectors, incorporation in
holding device. A set of reflective triangles shall be adequately
protected by enclosure in a box, rack or other adequate container specially
designed and constructed so that the reflectors may be readily extracted for
use.
(vi)
Certification. A red emergency reflective triangle designed
and constructed to comply with this section shall be plainly marked with the
certification of the manufacturer that it complies therewith.
(5) Three bidirectional emergency
reflective triangles that conform to the requirements of Federal Motor Vehicle
Safety Standard No. 125, section
571.125.
