Which color flag must be attached to the towing connections?

• A. Red
• B. White
• C. Orange
• D. Yellow

Answer: (A)

Red is used to signal a warning and draw attention to a potential hazard. When a vehicle is towing another vehicle or equipment, the towing connections and any part that sticks out beyond the vehicle can surprise drivers if it isn’t clearly seen. Attaching a red flag to the towing connection makes the danger immediately obvious to others, helping prevent rear-end or side-swipe crashes. The flag should be clearly visible and large enough to notice from a distance.

White, orange, and yellow don’t carry the same universal warning signal for towing hazards. White isn’t used for marking towing links, orange is typically reserved for construction or maintenance hazards, and yellow is a general caution color but not the standard for signaling a towing connection.
