Chevron signs are types of warning signs put on roadsides to warn motorists of upcoming sharp turns in the road. They are used in the United States as well as other parts of the world, including Canada and Europe. Like other road warning and construction signs, Chevron signs typically have bright yellow backgrounds and black lettering.
Occasionally Chevron signs are posted individually, but they are more often found in clusters. Depending on where they are used, Chevron signs contain different types of arrows. In the U.S., two types of Chevron signs are commonly used. Some Chevron signs exist as straight arrows, which run horizontally across the length of the sign. Other Chevron signs feature only the head of the arrow, which is magnified and covers the entire face of the sign. Regardless of shape, Chevron arrows are mounted on rectangular signs. These signs may be posted in various locations, such as at the site of a bend or curve in the road or farther ahead of the curve to warn drivers to start slowing down. Sometimes, Chevron signs are used temporarily, such as during construction and road maintenance projects. In these cases they may direct drivers to merge with other lanes to navigate around work areas.
