There are 30 to 35 million rural and suburban mailboxes in this country. These mailboxes must accommodate both the owner and the mail carrier. However, safety considerations are often overlooked.
Although crash reports related to mailboxes are sketchy, the limited data available suggests that 70 to 100 highway deaths in the U.S. each year could be attributed to mailboxes. This data relates the construction of the mailbox system, and especially its support, to the severity of the accident.
