In case a car runs off the road into this sign, these posts will cleanly snap off at ground level, reducing the damage to the vehicle.

Brilliant! (I assume they can still withstand strong winds?)
Yes sir. Here’s a decent guide to sign supports: http://www.trafficsign.us/signposts.html
And that rock-shaped object expands into a giant airbag, I bet? Please. What are you, a retired transportation engineer?
They’ve had this in Texas from way back. Part of it is not saving the car so much (just a pleasant by-product) as allowing them to reinstall the next sign with much less time/effort/expense.
I’ll have to let Matt speak to his “retirement” status, but I can tell you he is indeed a very talented transportation engineer – we miss him in the office.
We definitely don’t have those in Alabama, or atleast not that I have seen. There are plenty of dead signs around here. Then again I wonder if they chose not to have them here because we have a lot of Tornados and straight line winds. Flying sharp signs would not be good.
