Correct answer
30 km/h.
30 km/h, because this lorry’s general maximum is 80 km/h and its general minimum is half that: 40 km/h. Shoulder width does not change this lorry limit. Article 49 allows speeds below the minimum when traffic, vehicle or road conditions prevent maintaining it safely, among other regulatory cases. Do not accelerate to 40 km/h when that would be unsafe.
