Mailbox supports

Mailbox supports

A mailbox and its support are sometimes used for personal expression, but a review of Minnesota crash data provides a sobering reminder of the importance of crashworthy installations. Crashes involving mailboxes accounted for nearly 2,700 incidents and 354 personal injuries from 2014-2023.

Steel tractor wheels, concrete filled cream cans and welded chain are only a few examples for existing installations that are candidates for replacement. Minnesota Statue 169.072 considers any mailbox not meeting crashworthiness requirements a hazard and provides road authorities the ability to replace non-conforming installation.
