At what maximum speed limit can you drive a passenger car of maximum permissible weight 3 t, on a single-carriage expressway?

The D-7 'Expressway' sign visible on the right informs you that you are entering this type of road. According to Art. 20 para. 3 of the Road Traffic Act, on a single-carriageway expressway, the maximum permitted speed for a passenger car is 100 km/h. It should be remembered that on a dual-carriageway expressway, this limit is higher and amounts to 120 km/h.
