Correct answer
Yes.
Yes. This is R-406, a compulsory carriageway for lorries, tractor units and goods vans regardless of mass when no figure is displayed. A tonnage inscription or panel limits the obligation to vehicles or combinations whose MAM exceeds that figure. This is not S-3, the road reserved for motor vehicles. Other signs and restrictions still apply.
