I was under the impression that such a law exist based on past accidents where drivers have been seriously injured when they hit brick or stone mailbox posts. Old Fairground Rd. In
Johnston County has a number of such posts.
Maybe this isn't the place for this question, but, it is concern.

Thanks for the responses. At was a friend of mine, in fact, that run off the road and a brick
from one of the rigid mailbox stands went through his windshield and he now has permanent brain damage. I think this is the reason the law was passed. Close to my home, I saw where a car ran off the road, wiped out a mailbox on a wooden post and hit and killed a deer. I assume the driver was trying to avoid the deer. If that had been a rigid mailbox stand, the outcome could have been a similar incident. I will contact the DOT.
