If we drive at night with a truck whose load protrudes both at the front and the rear, how shall we mark it?

A)With a red light at the rear and a white one at the front.
B)With a red light at the rear, a white one at the front and a regulation panel of 50 centimetres per side.Correct
C)Only with the red light at the rear, plus the regulation panel of 50 centimetres per side.
In any case, the load protruding from the rear of vehicles, except 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 vehicle's axis.
When the load protrudes longitudinally across the entire width of the rear of the vehicle, we will place 2 panels and their stripes will form an inverted "V".
In addition, when driving at night or in conditions that significantly reduce visibility, we shall carry a red light at the rear and a white light at the front.
