- Major Highways are express roads that are not freeways, and always starts with DXXX. Similar to freeways, there might be an E-x number assigned as well.
- Minor Highways are mostly maintained by local authorities. There is no standard for road naming. We use this road type for through-going traffic or for longer distances connecting cities or towns.
- Ramps are entrance and exit roads to highways and have special functions for routing instructions. See the explanation on Interchanges and other connecting segments for detailed information.
