You are driving on a one-way street with signposting. What is correct?

Your answer is fully correct.

In a one-way street in Germany, you must position yourself as far to the left as possible if you intend to turn left. This is because traffic flows only in one direction, so the left side becomes the lane for turning left safely.

Additionally, parking is allowed on both sides of a one-way street, including the left-hand side. This is different from normal two-way streets, where parking on the left is often restricted or only allowed on certain sides.

However, parking against the direction of traffic (i.e., facing the opposite direction you are driving in) is not allowed, even on a one-way street. Vehicles must be parked in the same direction as the flow of traffic.

Understanding these rules helps you prepare for maneuvers safely and legally on one-way streets.
