Five full-scale crash test were conducted to evaluate the impact behavior of rural mailbox installations. Three of the five tests involved commonly used wood post supports, two of which were single box installations and the third was a four-box installation. The other two tests involved two promising new support concepts which utilized standard steel pipe. Both tests involved single box installations. Results showed that installations with multiple boxes mounted on boards pose a serious hazard to motorists since the board can easily penetrate the windshield. The results also showed that a pipe support post performs in a more desirable manner than does a wood post. Careful attention must be given to the box-to-post attachment to prevent separation during impact and thus minimize the potential for windshield penetration by the mailbox. (FHWA)
