Using the techniques outlined in NCHRP Report 350, the lateral OIV was calculated. The lateral OIV is based on vehicle c.g. lateral acceleration data. The computed lateral OIV was 10.2 m/s, below current FHWA safety performance levels.

The load cells measured eight separate forces on the rigid pole. The total load from summing the eight load cell signals was 301,280 N. The significant loads were contributed by the roof-rail, floor-sill, and the mid-point of the driver door. The peak loads from the roof-rail, mid-door, and floor-sill were 26,600 N, 110,400 N, and 193,600 N, respectively. Using torque equations, the height of the
