For convenience and practicality, mailbox installations have been allowed within the right-of-way of Maine’s public highway/roadways; however, it is important to recognize that such installations have two very important conditions:
The mailbox must be installed in accordance with applicable standards to ensure that mail can be delivered and that the mailbox does not create an obstacle or safety hazard to those that use or maintain the highway/roadway, and
The mailbox is installed entirely at the owner’s risk. In other words, if the mailbox incurs damage during any sort of highway/roadway operations or maintenance, the property owner is not entitled to replacement or compensation. In fact, if the mailbox was not installed in accordance with the applicable standards as stated above, the owner may even be held liable for injuries or damages that may have been incurred as a result.
