Vehicle response . A sharpened rod attached to the slip base pole punctured the vehicle 25 mm rearward of the vertical target tape denoting the intended target location. The driver door, floor pan, and B-pillar collapsed inward as the pole penetrated the occupant compartment. The roof rail crushed inward causing the windshield to crack. The intrusion continued until enough force was present to activate the slip base. The intrusion stopped when the truck frame rail contacted the pole, activating the slip base. The truck continued forward, pushing on the pole. The pole’s inertia and the sliding friction continued to retard the truck’s motion. The base activated approximately 0.032 s after initial contact and the bolts were free of the slip base flange at 0.044 s. The pole base plate was no longer in contact
