The main reason the white cloth is still used is the lack of an official protocol for drivers to communicate an emergency while on the road. Hazard lights alert other drivers to a stop, but don't allow them to convey the reason. In this communication gap, motorists developed this informal code which, over time, became a recognized practice in various countries in the region.
Understanding their meaning contributes to more empathetic and attentive driving. Even so, it's crucial to remember that road safety must always take precedence over any act of solidarity. When in doubt, the wisest course of action is to maintain a safe distance, reduce speed, and notify the authorities so they can provide appropriate assistance.
