If you drive a truck with a gross vehicle weight of over 3.5 t, what's the maximum speed at which you can drive once you go past this sign?

The visible D-43 sign "End of built-up area" indicates leaving an area where the 50 km/h speed limit applies. According to road traffic regulations, on a road outside a built-up area, the maximum permitted speed for a combination of vehicles consisting of a lorry with a Maximum Authorised Mass (MAM) of over 3.5 tonnes and a trailer is 70 km/h.
