Mailbox supports in the ten of millions exist on the “Federal Aid System” roadsides and are the closest devices in proximity to the traveled roadway of all roadside appurtenances. As with all clear-zone devices, they too must be crashworthy.
Segments of: "Interpretation Letter 2-547(I)-Relationship of the Terms Breakaway and Crashworthy"
"The definition of crashworthy is contained in Section 1A.13 of the MUTCD. This definition reads as follows: A characteristic of a roadside appurtenance that has been successfully crash tested in accordance with a national standard such as the National Cooperative Highway Research Program Report 350, "Recommended Procedures for Safety Performance Evaluation of Highway Features."
The 2002 AASHTO Roadside Design Guide (Chapter 4.1, Acceptance Criteria for Breakaway Supports) uses the term "breakaway" to describe all types of sign, luminaire, and traffic signal supports that are designed to yield when impacted by a vehicle. The Roadside Design Guide also indicates that the criteria used to determine if a support is considered breakaway can be found in the AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals. The AASHTO specifications have been revised so that the breakaway requirements are identical to the crashworthy requirements in NCHRP Report 350.
