Driving at an abnormally reduced speed without justified cause is prohibited (on motorways and dual carriageways below 60 km/h, and on other roads below half of the generic maximum for each vehicle).
Nevertheless, driving below the minimum speed limits is allowed for cycles, animal-drawn vehicles, special transports and special vehicles, or when traffic circumstances prevent maintaining a higher speed than the minimum without risk to traffic, as well as in cases of protection or escort of other vehicles, in which the speed shall be adjusted to that of the escorted vehicle.
When a vehicle cannot reach the required minimum speed and there is a risk of being overtaken, the emergency light or signal must be used.
Any driver who, due to emergency reasons, is forced to drive on a motorway or dual carriageway at an abnormally reduced speed must leave it at the first exit.
