In the absence of signage, what is the maximum speed allowed for a van when driving on a dual carriageway that runs within a built-up area?

On a dual carriageway running within a built-up area without specific signage, the maximum speed allowed for a van is **80 km/h**. This limit applies because, although it is a dual carriageway, the fact of driving within a populated area requires a reduced speed for safety reasons. Vans have the same speed restrictions as cars on this type of urban road.
