What must be attached to a load that exceeds the rear load projection limit?

• A. Warning lights
• B. Red flag
• C. Reflective tape
• D. Load covering

Answer: (B)

When a load exceeds the rear load projection limit, it is crucial to signal the increased length of the vehicle to other road users for safety reasons. Attaching a red flag at the end of the protruding load is a standard practice. This flag serves to visually indicate to drivers approaching from behind that there is a load extending beyond the usual length of the vehicle, thereby preventing potential accidents or misunderstandings.

The red flag is highly visible, especially in daylight, and meets regulatory requirements for load projection. Drivers who see the flag can maintain a safe distance or make necessary maneuvers to avoid a collision.

In contrast, while warning lights, reflective tape, and load coverings may serve other safety functions, they do not specifically fulfill the requirement to indicate an exceeding load projection in the same direct and universally recognized manner as a red flag does. This makes the red flag the appropriate and correct answer in this context.
