In this situation, when driving a lorry with a maximum gross weight exceeding 3.5 tonnes on an expressway, are you allowed to overtake another motor vehicle travelling at 75 km/h?

Explanation
Correct answer: No
No. On an expressway the permitted speed for a truck with a permissible gross weight over 3.5 t is 80 km/h (under art. 18 para. 3). With the overtaken vehicle travelling at 75 km/h, the speed difference is only 5 km/h, so the overtaking would take too long, blocking the left-hand lane and endangering road safety.
