This sign is displayed on

• A. the back of slow moving vehicles
• B. the front of slow moving vehicles
• C. the left side of slow moving vehicles
• D. the top of slow moving vehicles

Answer: (A)

The sign is shown on the rear of slow-moving vehicles to warn drivers behind them that the vehicle ahead is traveling slowly, so they can slow down or pass safely. It’s designed to be highly visible to traffic approaching from behind, especially at night thanks to reflective material. Putting the sign on the back ensures that the warning reaches following drivers; if it were on the front, top, or sides, drivers behind wouldn’t see it as readily, defeating its purpose. This is why slow-moving vehicles like tractors or construction equipment carry the emblem on the rear.
