Question

DentroTest · Accepted Answer

The R-306 sign prohibits trucks with a maximum authorized mass (MAM) above 3,500 kg from overtaking motor vehicles traveling on the roadway, even when the maneuver does not involve entering the area reserved for the opposite direction. Since 1 July 2025 (Royal Decree 465/2025) the sign no longer has an exception for motorcycles, which are also motor vehicles: the truck must not overtake any of them, not even without entering the opposite lane. The old rule, which allowed overtaking two-wheeled motorcycles without entering the opposite direction, is no longer valid. And the speed with which the maneuver is completed does not exempt from the prohibition either.
