What following distance from the vehicle ahead must a vehicle with a GVW of more than 3,500 kg maintain when travelling on a dual carriageway?

A)At least 50 metres.
B)50 metres if not intending to overtake.
C)The distance that allows stopping without colliding with it.Correct
When travelling behind another vehicle, a space must be left that allows stopping, in the event of sudden braking, without colliding with it, taking into account the speed and the grip and braking conditions. Furthermore, if we are travelling without the intention of overtaking, this gap must be such that it allows the vehicle behind us to overtake. For these purposes, vehicles with a GVW of more than 3,500 kg and vehicles and vehicle combinations of more than 10 metres must maintain a distance of 50 metres.
However, it will be sufficient to maintain a distance to avoid a collision (at these points there are no longer specific metres):
- In built-up areas.
- Where overtaking is prohibited.
- Where there is more than one lane in the same direction. (This point is the case for motorways and dual carriageways as they always have more than one lane).
- When traffic is congested.
- When intending to overtake.
