Loads that protrude from the rear of the vehicle, whether on a truck or a passenger car, must be marked with the panel in the image. If we drive in adverse weather conditions that reduce visibility or from sunset to sunrise, we must also display a red light.
In addition, when the load protrudes longitudinally over the entire width of the rear of the vehicle, we will place 2 panels and their stripes will form an inverted "V".
