What is the purpose of the yellow 'Slow Moving Vehicle' sign?

The yellow 'Slow Moving Vehicle' sign serves the important role of alerting drivers that a vehicle is traveling at speeds significantly lower than the typical flow of traffic on that road. This sign is particularly relevant for vehicles that cannot maintain the standard speed limit, such as farm equipment, horse-drawn vehicles, or other specialized transportation. By providing this warning, the sign helps ensure that approaching drivers can adjust their speed and driving tactics to avoid potential collisions and maintain safety on the roadway.

In recognizing the context of this sign, it's important to understand that it does not indicate construction zones, pedestrian crossings, or school zones, which are represented by different signage. These distinctions help streamline road safety by ensuring all road users are aware of various potential hazards and their surroundings.
