On what roads does the recommended speed of 130 km/h apply?

The recommended speed of 130 km/h in Germany applies primarily on motorways (autobahns), where higher speeds are typical and safe conditions often exist. It is also advised on dual carriageways outside built-up areas, meaning roads that have separate lanes for each direction of traffic, even if they are not classified as motorways. Additionally, this recommendation extends to roads outside built-up areas that have at least two marked lanes for each direction, allowing for safer overtaking and smoother traffic flow. The idea is that on roads designed for higher speeds and with proper lane separation, driving at or below 130 km/h is safest. This recommendation is not a strict speed limit but a guideline to promote safety under normal driving conditions.
