Section 532.520 Postal
Patron Maintenance
a) Postal regulations require that the postal patron maintain his
mailbox and mounting structure in good repair. Mail boxes and their supporting
structures are the property of the mail route patron and patrons should
familiarize themselves with U.S. Postal regulations.
b) Postal regulations require mailbox patrons to remove
obstructions including snow that makes delivery difficult. However, State
Highway maintenance forces will remove snow from mailbox turnouts under the
conditions mentioned in Section 532.510.
