Four full-scale crash tests were conducted on inertia barriers using scrap tires as containers for the sand mass. The first barrier utilized additional tires with empty beverage cans in the annular space and banded together for a support base. The bases of scrap tires collected under the front of the impacting vehicle and caused it to ramp upward. The second scrap tire-sand barrier was tested in which the modules were supported by a 14 gage welded wire cage. This inertia barrier performed satisfactorily. The ramping of the vehicle was eliminated and the vehicle was stopped smoothly. In the third and fourth tests the supports were fabricated from used 55 gal paint drums. When the chimes and tops and bottoms were removed and a series of vertical cuts made in the drum, the barrier performed satisfactorily. There was a slight tendency toward vertical ramping, but the vehicle was stopped smoothly.
