What is the name of the reflective orange triangle with a red border on each of the three sides?

The reflective orange triangle with a red border on each of its three sides is known as the Slow-Moving Vehicle Emblem. This emblem is specifically designed to alert other drivers that a vehicle is traveling at a lower speed, typically at or below 25 miles per hour. It is commonly used on farm equipment, construction vehicles, and other slow-moving vehicles that are not able to keep pace with regular traffic.

The use of this emblem is important for safety on the road, as it provides visual warning to drivers that they need to be cautious and prepared to slow down or pass safely. The distinct color and shape make it easily recognizable, fulfilling its function of increasing awareness and preventing accidents involving slow-moving vehicles.

In contrast, other options listed do not accurately describe this specific emblem or serve the same purpose. A warning sign is a broader category that includes various signs used to caution drivers of hazards, while a safety triangle may refer to different types of safety signals in a general sense, and an agricultural symbol might refer to logos or icons representing farming but not specifically the slow-moving vehicle designation.
