The panel that indicates the load protruding from the rear is mandatory and cannot be replaced by any other device.
The load that protrudes from the rear of vehicles, except for those less than 1 metre wide, shall be marked with a 50 by 50 cm panel with alternating diagonal red and white stripes, placed at the rear end of the load and perpendicular to the axis of the vehicle.
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".
