MUTCD Regulations for Traffic Cones – Reflective Collar Requirements

Reflective Requirements for Traffic Cones


Our Summary

Traffic Cones need to be orange in color.   For daytime and low speed applications cones need to be 18 inches or taller and do not need reflective bands.  It must be daytime AND traffic must be limited to 40 miles per hour or less.

For areas where traffic is going faster than 45 mph you must use a 28 inch – 36 inch orange cone.  The cone must have two reflective bands.  The top band must be 6″ tall and the bottom band must be 4″ tall.  The space between the two bands needs to be 2″.

Section 6F.64 Cones
Standard:
01 Cones (see Figure 6F-7) shall be predominantly orange and shall be made of a material that can be struck without causing damage to the impacting vehicle. For daytime and low-speed roadways, cones shall
be not less than 18 inches in height. When cones are used on freeways and other high-speed highways or at night on all highways, or when more conspicuous guidance is needed, cones shall be a minimum of 28 inches
in height.
02 For nighttime use, cones shall be retroreflectorized or equipped with lighting devices for maximum visibility. Retroreflectorization of cones that are 28 to 36 inches in height shall be provided by a 6-inch wide
white band located 3 to 4 inches from the top of the cone and an additional 4-inch wide white band located approximately 2 inches below the 6-inch band.
03 Retroreflectorization of cones that are more than 36 inches in height shall be provided by horizontal, circumferential, alternating orange and white retroreflective stripes that are 4 to 6 inches wide. Each cone shall have a minimum of two orange and two white stripes with the top stripe being orange. Any non-retroreflective spaces between the orange and white stripes shall not exceed 3 inches in width.
Option:
04 Traffic cones may be used to channelize road users, divide opposing vehicular traffic lanes, divide lanes when two or more lanes are kept open in the same direction, and delineate short duration maintenance and utility work.
Guidance:
05 Steps should be taken to minimize the possibility of cones being blown over or displaced by wind or moving vehicular traffic.
Option:
06 Cones may be doubled up to increase their weight.
Support:
07 Some cones are constructed with bases that can be filled with ballast. Others have specially weighted bases, or weight such as sandbag rings that can be dropped over the cones and onto the base to provide added stability.
Guidance:
08 Ballast should be kept to the minimum amount needed.
