Do roads have speed limits: Partially.
If so, where: Everywhere except for highways.
What are the speed limits:
- Within municipalities: 60 km/h.
On country roads (State Roads): varies by state (lowest is 90 km/h, highest is 120 km/h).
Single-carriageway Federal Roads: 100/120 km/h.
Multiple-carriageway highways: no limit.
Does your nation have freeways: Yes.
Does your nation have numbered roads: Yes.
If so, what system do the numbers follow:
The highway (Autobahn) system has a logical pattern. They are called A1, A2 etc.
East-west highways have even numbers.
North-south highways have odd numbers.
Ringroads have numbers ending in 0.
Single-digit numbers are main highways with a national meaning, double-digit numbers are those with a regional meaning. Three-digit numbers are mostly bypasses and feeder roads.
Federal Routes (B1, B2, etc.) follow a similar pattern. The B1 to B10 roads are main routes with a national meaning. From there, the numbers start in the southeast and radiate clockwise around the center, until they reach the southeast again; in a second process, more routes got numbered again, this time radiating counter-clockwise.
State Road numberings vary by state.
