What color are slow-moving vehicle signs?

Slow-moving vehicle signs are specifically designed to alert other drivers that a vehicle is traveling at a slower speed than the normal traffic flow, typically less than 25 miles per hour. The correct choice, which features an orange color with a red reflective border, is used widely across states for this purpose. The bright orange color enhances visibility, particularly in low light conditions or adverse weather, while the red reflective border helps to draw immediate attention to the sign, ensuring that drivers can identify the presence of a slow-moving vehicle from a distance.

The other options do not accurately represent the color scheme standardized for slow-moving vehicle signs, underscoring the importance of recognizing these specific visual cues while driving. This is essential for maintaining safety on the road, especially when sharing the roadway with less agile vehicles, like farm equipment or construction vehicles.
