The view is obstructed by bushes or a wall. Now what?
Sometimes there is sight obstructing vegetation. In general, in a 30 km/h zone, obstruction of visibility only occurs if the vegetation is close to the edge of the roadway and is so high that traffic (from a vehicle) cannot see over it. If the vegetation is well away from the roadway, there is generally sufficient opportunity, if necessary at an appropriate speed, to drive up to the intersection and thus gain visibility of the intersecting traffic.
At higher speeds (e.g., 50 km/h), sight obstruction may be present earlier. Whether there is sight obstructing vegetation is assessed by the traffic engineer. If visibility-obstructing vegetation is present, the owner of the vegetation is obliged to prune or possibly remove it.
If a wall of a barn, for example, creates an obstruction to visibility, then traffic should adapt its behavior to this situation. The municipality does not usually take action in such cases.
