Driving on roads and highways requires attention to various signals: brake lights, hazard lights, gestures from other drivers, and road signs. However, there is an informal code that many drivers use, which can be confusing for those who see it for the first time: a white cloth hanging from the window. Although not stipulated in any regulation, this practice persists as a way to communicate a specific situation inside the vehicle.
The Origin of an Unofficial Signal:
Unlike flashing lights or reflective triangles, the white cloth is not mentioned in any driver's manual or traffic law. It is a custom that spread among drivers as an improvised way to communicate an emergency while the vehicle is in motion or stopped on the side of the road.
The choice of color is not accidental: white is historically associated with truce, peace, and a plea for help. That's why, when they see it flickering in the window, many drivers interpret it as a sign that something is wrong inside the car and pay closer attention.
Common situations in which it is used:
There are several reasons why a driver might use this visual aid. The most frequent are:
Mechanical failure: when the vehicle stops on the shoulder due to a technical problem and the driver wishes to signal their presence to avoid collisions or request assistance.
Medical emergency: the driver is trying to alert others that they are transporting a person who needs urgent care.
Caravans and group trips: in funeral processions, religious pilgrimages, or group trips, the white stripe serves to identify vehicles that are part of the same group.
Lack of fuel: in some cases, it is used to indicate that the car has run out of gasoline or diesel.
Does it give priority?
One of the most frequent questions is whether this gesture gives the driver priority over other vehicles. The answer is clear: no. Traffic laws establish that only official emergency vehicles have priority, provided they are traveling with their lights and sirens activated.
These vehicles include:
