But there’s technically no sign prohibiting that. However that’s besides the point. The highway should be tagged as vehicle:practical=no since there’s a physical barrier making it impassable with a car. Also in case of emergency it will nicely represent that a pedestrian could jump over it, even though it’s not permitted by law in most situations.
My question is what tag should I use to signify that in case of emergency an emergency vehicle will try to break through the barrier whereas they couldn’t do the same to a barrier=wall.
