On a two-lane road with two-way traffic, where must a special vehicle with a Maximum Authorized Mass (MAM) exceeding 3,500 kg normally circulate?

Question

DentroTest · Accepted Answer

The correct answer is in the lane on their right. As a general rule, special vehicles with a MAM exceeding 3,500 kg follow the same positioning rules as trucks or cars: they must travel on the roadway (calzada) and not on the shoulder. It is important to distinguish this from special vehicles up to 3,500 kg, which are required to use the shoulder if it exists and is passable. Therefore: They cannot use the right shoulder (reserved for light special vehicles, cycles, mopeds, etc.). They cannot use the left lane, because on a two-lane, two-way road, the left lane is for oncoming traffic (invading it is dangerous unless overtaking, if permitted).
