Zusammenfassung:A breakaway utility pole (9, 109) mounting structure. The mounting structure presents a base portion (11', 16 or 20) within which the end portion (10, 110) of the pole (9, 109) is telescopically received. The base portion (11', 16 or 20) of the mounting structure extends below ground level, and an adhesive material (17, 117) bonds the pole end portion (10, 110) to the base portion (11', 16 or 20). The adhesive material (17, 117) is adapted to fail when the pole (9, 109) is subjected to an impact at a predetermined distance above ground level from a vehicle of predetermined minimum weight moving at a predetermined minimum speed.
