What is the maximum permitted speed on an expressway for a goods vehicle with a maximum authorised mass of 4 t?
Explanation
Heavy goods vehicles with a maximum authorised mass over 3.5 t have a lower speed limit on motorways and expressways than cars do. Such a vehicle may travel no faster than 90 km/h, so the 4 t goods vehicle here is held to that limit.
KET reference: KET 131.3: goods vehicles over 3.5 t may not exceed 90 km/h on motorways and expressways.
