In Minnesota snow presents a special problem for rural mailbox installations. So, Minnesota Department of Transportation (Mn/DOT) developed cantilevered mailbox support designs. Recent studies had shown that certain rural mailbox installations easily penetrated the passenger compartment of an impacting vehicle. These same studies pointed out that a large number of people are seriously injured or killed each year as a result of mailbox collisions. Therefore, Mn/DOT initiated full scale crash test to ascertain the crashworthiness of its cantilevered design.
