Yesterday Salem Reporter published on a welcome sign drivers keep hitting.

They say,
Since 2021, the sign has been struck at least once a year....“There has been no official determination for why the sign is frequently damaged,” according to Trevor Smith, spokesman for Salem’s Public Works Department....The frequent damage to the sign began a year after it was built [in 1994].
Seemingly, it's a mystery why it happens.
But this is centrally a refusal to see, an instance of autoist blind spots.
Zooming out just a pinch, you see the sign at an intersection of stroads, overengineered for speed. The southbound continuation of River Road operates like a slip lane and even a highway exit lane.
Going South: Big stroads, overengineered for speed |
Drivers are going at high rates of speed here.
Going North: "Do not enter" and sweeping curve (rubble from a previous crash also!) |
In the other direction, there's a stroad with a sweeping curve and the "straight" movement is into that one-way slip lane.
The spandrel, the unused triangle in which the sign is mounted, is a result of engineering roads for speed and capacity.
Last minute lane decisions are a likely cause of at least some crashes. The problem to solve is high speed, and the solution is much slower speed. This is a drivers, driving, and car problem, not a sign location problem.
Even if the compound intersection is tricky, slower speeds allow drivers to parse the intersection and make unrushed decisions.
We might also compare it with similar "roadway departure" crashes.
