What is the shape of the Slow Moving Vehicle Emblem sign?

• A. Diamond
• B. Pentagon
• C. Triangle
• D. Circle

Answer: (C)

The emblem uses a triangular shape because triangles are universally read as a warning cue. Slow-moving vehicles, like farm equipment, travel much slower on roads and can surprise drivers who aren’t prepared to slow down. Placing a bright orange triangle with a red border on the rear of these vehicles instantly signals to following drivers to reduce speed and proceed with caution. The triangle is easy to spot at a glance, even from a distance or at night, which helps prevent collisions as these vehicles move at about 25 mph or less. Remember, this emblem is distinct from the common road signs you see on the side of the road; the vehicle-mounted sign itself is specifically a triangle, which is why the correct choice is the triangle shape.
