What signifies a slow-moving vehicle?

A slow-moving vehicle is signified by a red triangle with an orange center. This reflective emblem is designed to alert other drivers that the vehicle is traveling at a lower speed than the flow of traffic, typically 25 mph or less. The bright colors and shape of the emblem help ensure visibility, making it easier for other drivers to recognize a slow-moving vehicle and take appropriate precautions.

In contrast, the other choices represent different types of signage: a yellow diamond with a horse symbol typically indicates horse-drawn vehicles, while blue rectangles often denote services or facilities available ahead. A green circle with a speed limit is usually associated with indicating areas where speed limits apply, but it does not communicate the concept of slow-moving vehicles. Understanding these distinctions is crucial for recognizing and responding to various warning signs on the road.
