An emblem displayed on vehicles that operate at speeds significantly below the normal flow of traffic. This marking, often triangular and fluorescent orange, is intended to alert other drivers to the presence of a potentially slower-moving object on the roadway. An example includes agricultural machinery, construction equipment, or horse-drawn carriages traveling on public roads.
The presence of these indicators is crucial for promoting road safety. They serve as a visual warning, allowing faster-moving vehicles to adjust their speed and driving behavior accordingly, thereby reducing the risk of collisions. Initially developed to address the specific challenges posed by farm equipment sharing roadways with automobiles, the concept has been widely adopted and codified into traffic regulations in many jurisdictions.
