At what maximum speed are you allowed to drive on the road beyond this sign if you are driving a lorry of gross vehicle weight rating over 3.5 tons?
Show the correct answer
Correct answer
A. 80 km/h.
Explanation
In the photo you are driving along a dual carriageway behind a lorry, and on the right there is sign D-7 "expressway" - a blue square with a white car symbol. When driving a lorry with a maximum permissible mass of over 3.5 t, you may drive at most at 80 km/h - answer A.
The Road Traffic Act states that the speed limit for a vehicle combination or a vehicle other than a passenger car, a motorcycle and a lorry of up to 3.5 t, outside built-up areas, is 80 km/h on a motorway, an expressway or a dual carriageway with at least two lanes in each direction, and 70 km/h on other roads. So for a lorry over 3.5 t, 80 km/h is the upper limit on every Polish road - no sign or road class raises it. That is why the answers 100 and 120 km/h are wrong: these limits apply to passenger cars and lorries of up to 3.5 t. On an expressway you must also keep a distance of at least half your speed in metres, which is 40 m at 80 km/h.
