If the mailbox is mounted on the house he must have a clear path to the mailbox. If you are mounting your mailbox on a rural road, mount it so the bottom of the mailbox is 47 inches from the surface of the road. Mount the mailbox far enough off the side of the road where it won't get hit. 12" is a good figure to use. Remember that school buses and trucks have mirrors that stick out on the right side that could hit your mailbox. If your mailbox is on a street with a curb, mount the mailbox so the bottom of the mailbox is 47" from the street. Mount the front of the mailbox 9" from the curb.
