A lorry over 10 metres in total length including its load travels without signalling an intention to overtake and outside a tunnel. With traffic not saturated and overtaking permitted, on which road must it additionally leave at least 50 metres to help following traffic overtake?

Correct answer

When travelling on a conventional road, outside a built-up area, with one lane for each direction.

On a conventional road outside a built-up area with one lane in the lorry’s direction, under the stated conditions. Article 54.2’s 50 metres help following traffic overtake; they do not replace the gap needed to stop without collision. This additional obligation does not apply in built-up areas, where overtaking is prohibited, with more than one lane in the same direction or in saturated traffic preventing overtaking. Other minima can still apply.
