When driving outside built-up areas on a conventional road at the wheel of a truck with a maximum authorized mass (MAM) of 5,000 kg, below what speed limit is it prohibited to drive as a general rule?

Question

DentroTest · Accepted Answer

The General Traffic Regulations establish that driving at an abnormally low speed without justified cause is prohibited. As a general rule, on conventional roads the mandatory minimum speed for any vehicle is half of the general maximum speed set for that vehicle on that road. Since the general maximum speed for a truck on a conventional road is 80 km/h, its minimum permitted speed is 40 km/h (half of its maximum). The 50 km/h and 60 km/h options are incorrect, 60 km/h being the minimum limit set in general for motorways and dual carriageways, but not for conventional roads.
