Mailbox Roadside Hazard Information

Do You Own a Roadside Hazard??

Anything alongside a street or highway that is a possible source of damage or injury if struck by an errant vehicle is considered a roadside hazard. Since nearly 50% of Colorado’s fatal accidents involve vehicles that run off the road, mailboxes designed to be aesthetically pleasing may be a hazard waiting to be struck.

The design of a mailbox and its support have a direct correlation to the damage/injury severity caused by the vehicle impact. Massive mailbox supports such as rock columns, plow blades, railroad ties are potentially hazardous to the motorist. Mailbox designs that are shown in this pamphlet are approved by Postal authorities and the Department of Highways and are not considered to be a hazard.

Cantilever Mailbox Support

Supports that bend are desirable although 4” x 4” wood post may be used. Boxes should be properly attached so as not to become “missiles” if impacted.

Multiple Mailbox Support

Can You Afford a Lawsuit??

Cantilever and multiple mailbox supports eliminate the chance of “spearing” an occupant of a motor vehicle.

There are in excess of 30 million mailboxes in the United States. As many as 100 fatalities a year occur as a result of vehicles colliding with these mailboxes. The potential for disabling injury and the resulting civil action is reduced when mailboxes are installed using approved methods and materials that are designed with highway safety in mind. Remember, the mailbox owner may be held liable in case of collision.

• Do you want to be responsible for serious injury to others?
• Do you want to be involved in a lengthy liability suit?
