Classification – motorways and speed (2)

In an earlier post (see here) I wrote:

 Maybe there should be different sub-classes of motorway, such as

  • Class A (speed limit of 120 km/hr)
  • Class B (speed limit of 120 km/hr, no emergency lanes)
  • Class C (speed limit of 80 km/hr)

Portugal is one country which seems already to have a sub-classification for motorways. The country’s INIR (Institute of Road Infrastructure) has a document which shows the following breakdown:

Portugal 22
