When driving a truck on a motorway or dual carriageway, what safety distance must we keep from the vehicle ahead of us?

Question

DentroTest · Accepted Answer

In accordance with the General Traffic Regulations, every driver must keep from the vehicle ahead a gap that allows them to stop in the event of sudden braking without colliding with it (safety distance). On conventional roads with one lane in each direction, heavy vehicles (maximum authorized mass (MAM) over 3,500 kg or length over 10 meters) must also leave a gap of 50 meters that allows them to be overtaken safely. On motorways and dual carriageways, since there is more than one lane for the same direction, that obligation does not apply (Article 54(3)), so only the distance essential to avoid a rear-end collision is required. That is why it is incorrect to add space to facilitate being overtaken, and there is no general fixed figure of 50 meters for motorways either.
