When I lived in Mobile, AL it seemed the "hot thing to do" for the HS kids was
tumping over brick mailboxes. It seemes the typical construction was to pour
a failr small concrete base and then just run the brick on it. They
apparently were not that hard to tump into the street.
I sunk several pieces of rebar through the core and bored into the ground
before filling it with concrete. No way they were gonna tip that - then I
considered the car impact issue.
I searched but couldn't find anything about mail box spec except for min/max
height and distance from the curb - all based on it being reachable by the
mail person. If you think about it, how would you measure the frangiblity?
Some of those a pretty massive and incorporate planters, etc. Some
neighborhoods have pretty massive brick entrances, they aren't break-away.
I recall that one of the neighbors had a beautiful, somewhat intricate stacked
stone mail box that looked pretty fragile... He surrounded it with some
serious posts about 3' high that would have done a number on any encroaching
cars.
Looking forward to your pix!

Subject: [Shop-talk] Mailbox to end all mailboxes

I have a question about mailbox posts. Does anyone know if there is a
requirement for your mailbox to "break away" if a car hits it?
Here is my problem, in my rural area of NJ, we get lots of wet snow. The
plow drivers are off season NASCAR drivers practicing their time trials as
they plow.
So my mail box next knocked down every now and then.
The first step I did was to pave about 10' in from the edge of the road.
This means there is now a 10' gap from where they are plowing to my
mailbox. It didn't take them long to figure out the new speeds they need
to go in order to knock it down at that distance.
The county says they are not responsible for mailboxes knocked over by
plows. (and I need to stay on the good side of my county guys.)
So, I figured I'd make a mailbox post that was indestructible.
What I did was take 2 1/2" rebar posts (two of them) and concreted them
into the ground 20" and they are 19" apart. Then I welded a 6" C beam
across the top of them, and welded another 6" C beam to that for the
mailbox to be attached to.
But I started thinking (always dangerous for me to do) that if a car was
to go off the road and hit this thing, it would be "Car, meet immovable
object" and I was wondering if I'm liable.
Now don't get me wrong, if there are any requirements, I'll just add a
guardrail around this thing as the mail box isn't going anywhere anytime
soon.
I'll post pictures the first nice day I get of the mail boxes, and the two
navigational buoys I added to the end of my driveway for those of you with
more time on your hands then you need. 8>)
