position. The dummy, pickup truck, and lighting standard bolts were instrumented with various transducers to record pertinent test data. The Valmont Industries Slip Away lighting standard is currently used on the National Highway System (NHS) in several states. The slip-base bolts used to clamp the slip base of the pole to the foundation base plate were 32-mm strain gage bolts pretensioned to 44,500 N each the morning of the test.
TEST MATRIX One broadside crash test was conducted in support of the FHWAs computer simulation program. The vehicle used was a 1994 Chevrolet C2500 pickup truck. The pickup truck was oriented on the FOIL runway perpendicular to the runway centerline (broadside-impact). A Valmont Industries lighting standard was erected on the FOIL runway foundation base plate in the impact zone. An SIDH3 dummy was placed in the driver seat in accordance with FMVSS 214. The lighting standard was aligned with a point on the driver door just forward of the SIDH3's head so as not to allow contact between the SIDH3's head and the pole. This point was later determined to be 1320 mm rearward of the pickup trucks front axle or 102 mm forward of the pickup trucks longitudinal center of gravity (c.g.). Table 1 outlines the test matrix followed for the broadside crash test.

TEST VEHICLE
The test vehicle used was a 1994 Chevrolet C2500 pickup truck. The pickup truck was equipped with standard equipment and options. Prior to the test, the truck was drained of all fluids and the curb weight, sill attitudes, and the vehicles physical parameters were measured. A NHTSA-supplied OSCAR was used to determine the three-dimensional coordinate of the SIDH3's H-point relative to the driver door-striker. The measurement was recorded and was used the day of the test to position the dummy in the driver seat just before the test. The test vehicle was
