This report documents the results of Phase 1-A testing for NHTSA's 1997-1998 Light Vehicle Rollover Research program. This phase was an initial, exploratory study of using test track maneuvers to quantify on-road, untripped rollover propensity. This study examined a broad range of maneuvers that might induce on-road, untripped rollover including: J-Turn, J-Turn With Pulse Braking, Brake and Steer, Steering Reversal, Toyota Fishhook, Double Lane Change, Split-Mu Two Wheels Off-Road Recovery Simulation, and Toyota Fishhook with Pulse Braking. Three vehicles were selected for the Phase 1-a testing. The vehicles selected were a 1984 Ford Bronco II, a 1997 Jeep Cherokee, and a 1990 Toyota 4Runner. These test vehicles were not in new condition. None of the test vehicles necessarily performed as would new vehicle without outriggers. However, this was not important for the Phase 1-A research. The goal of the Phase 1-A research was maneuver selection and test procedure development, not vehicle characterization.
