What color cloth must be placed on the towing rope when towing a broken-down vehicle?

When towing a broken-down vehicle, a white cloth must be placed on the towing rope. This practice serves as a signal to other road users indicating that the vehicle is being towed. The use of white is important because it is a universally recognized color for signaling and enhances visibility, ensuring that other drivers are aware of the situation. This helps to prevent accidents and promotes safety on the road, as other drivers can easily see the towed vehicle and understand that it may be moving slower than usual or is being maneuvered in a potentially hazardous situation.

In contrast, other colors like red, blue, and green are not commonly used for this specific purpose, and could cause confusion among drivers who may misinterpret those signals. Therefore, using a white cloth on the towing rope is the standard and safest practice in Japan, contributing to overall road safety.
