Thank you InsertUser for your answer,
the max_age is interesting, but I'm not sure it's adapted to that situation : It's not forbidden for people older than X. It depends on the size of the vehicle, and it's not a value, it's a category : for children. I couldn't decide which age is the correct one... For "playground", a sign often indicate an age range, but not in that situation. Maybe the answer is 12 ? https://taginfo.openstreetmap.org/keys/max_age#projects
It if is actually a vehicle size issue, then
maxheightormaxlengthmight be suitable with a bit of generous interpretation (although these are normally for legal limitsmaxheight:physicalmight be more apt). Whatever you settle on I think a note or description might be a useful addition until such times as we have "proper" standard tagging for this.
