Object Markers on Mailbox Supports
On two-lane, two-way roads, object markers should be placed on both sides of the mailbox support. In other cases, mailboxes should have a yellow Type 2 object marker facing traffic on the near side of the roadway. The Type 2 object marker can be either of the following:
- A 6 inch wide by 12 inch tall rectangular unit with reflective sheeting bolted or affixed to the support.
- A 12 inch strip of sheeting wrapped around the support post.
The top of the Type 2 object marker should be 6-8 inches below the bottom of the mailbox. Figures 9-19 and 9-20 illustrate the use of the object marker on mailbox supports.
