Correct answer
80 km/h.
It is 80 km/h. A lorry’s general motorway and dual-carriageway maximum is 90 km/h. Dangerous-goods transport reduces the applicable limit by 10 km/h; the question excludes that case. Overtaking does not permit a speed increase above the limit. Always observe lower limits and adapt speed to the road, visibility, grip and traffic.
