This paper discusses the results of five full-scale crash tests, using light automobiles, designed to assess the hazard to motorists posed by roadside mailbox installations. Three of the tests involved commonly used wood post supports, two of which were single box installations and the third a four-box installation. The other two tests involved two promising new support concepts which utilized standard steel pipe, both of which involved single box installations. Results showed that since most mailboxes are mounted at a height which places the box in direct line with the windshield of many vehicles, it is necessary that the box-to-post attachment be strong enough to prevent separation during impact and thus reduce potential for the box to strike the windshield; therefore, a pipe post is more desirable than a wood post. Multiple box installations are deemed hazardous; because they contain a beam or support member running parallel to the roadway which, when impacted, can penetrate the windshield.
