If driving on a motorway with very thick fog, is it permitted to drive at an unusually low speed?

Question

DentroTest · Accepted Answer

Yes, it is permitted. Although the general rule states that the minimum speed on motorways and dual carriageways is 60 km/h (driving below this is considered an unusually low speed), there are exceptions for justified causes. Thick fog, heavy rain, or snow are circumstances that reduce safety and visibility. In these cases, the driver is obliged to moderate their speed as much as necessary, even below the generic minimum limit, to be able to stop the vehicle within their field of vision and avoid accidents. Safety takes precedence over the minimum limit in adverse conditions.
