When drawing another vehicle with a chain, what should be displayed at the connection?

When a vehicle is being towed or drawn with a chain, safety is paramount, and it’s crucial to ensure that the connection point is clearly visible to other drivers. A white flag is typically used in this context because it is a universal symbol indicating a warning, particularly that a vehicle is being drawn or towed.

Displaying a white flag at the connection ensures that approaching vehicles are alerted to the situation, allowing them to adjust their speed and distance appropriately. This visibility reduces the risk of accidents, especially in situations where a chain connection could otherwise be obscured.

The other colors listed do not convey the same standard warning associated with towed vehicles and may not be recognized, leading to potential confusion or increased risks on the road. Thus, using a white flag is the correct and standard practice for indicating that a vehicle is being towed.
