White Cloth Signal Used by Drivers to Indicate Emergency Situations

Drivers sometimes hang a piece of white cloth from a car window or door to signal that they need assistance or are facing an urgent problem. The gesture is not defined in most national traffic codes, but it is recognized in some regions as an informal alert for mechanical breakdowns, medical emergencies, or other urgent needs.

In Romania, the practice has appeared online, with motorists describing the white cloth as a historic symbol of peace that has been adapted for roadside help. Romanian traffic legislation does not expressly define the cloth as an official warning, so authorities advise callers to use emergency services (112) when a medical emergency is suspected. In the United States, the North Carolina Driver's Manual mentions attaching a white cloth to the left‑hand door handle or antenna to make a vehicle’s distress visible, especially when the car is stopped due to a malfunction.
