A permanent sign that provides additional emphasis and guidance for the driver regarding a horizontal change in direction ahead, particularly a sharp change, is called a “Chevron Sign.”
Explanation:
Chevron signs are warning signs shaped like arrows that are placed along the roadway to indicate a sharp curve or change in direction. These signs are typically used in situations where the road deviates significantly from a straight path, such as at sharp bends, turns, or curves. The purpose of these signs is to enhance driver awareness and promote safety by alerting them to the upcoming change in direction, thereby allowing them to adjust their speed and steering accordingly.
The chevron symbol is universally recognized, and the signs are often brightly colored (usually yellow with black arrows) to ensure high visibility, especially in low-light conditions. They are strategically positioned in advance of the curve, allowing drivers ample time to react. The placement of multiple chevron signs along a winding road helps to reinforce the need for caution as the road continues to curve.
Additionally, these signs are part of a broader category of traffic control devices designed to manage vehicle behavior on the road. They complement other warnings, such as speed limit signs and general curve warnings, creating a comprehensive system of guidance.
In many regions, chevron signs are also reflective, increasing visibility at night and in adverse weather conditions. The effectiveness of chevron signs in preventing accidents and promoting safer driving behavior has been supported by various studies, which show that their use can significantly reduce the incidence of collisions at sharp turns and curves.
In summary, chevron signs serve as critical tools for enhancing road safety by clearly communicating the need for caution due to a horizontal change in direction, particularly when that change is sharp and may pose a hazard if not approached correctly.
