§ 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.
