What is the maximum speed you are allowed to drive a car on roads with one marked lane for each direction outside built-up areas?

On roads outside built-up areas in Germany that have one marked lane for each direction, the general speed limit is 100 km/h for cars. This rule helps ensure safety on these two-lane roads, which may have oncoming traffic and limited opportunities for overtaking. Speed limits can sometimes be lower if indicated by signs, but without specific signs, 100 km/h is the maximum allowed speed. This standard helps balance efficient travel with safety considerations.
