At a school this is limited to 30 by the well-known 30 sign. Directly behind the school a federal road crosses (two lanes each direction), which is of course also authorized to drive across from our road, at an elaborate traffic light crossing. After that our road runs on again as an authorised road. We are still located inside. There are no further speed signs of any height or signs for the suspension. After the crossing of the Bundesstrasse on “our” road, is the speed valid?
