Offset Barrier Crash Test Protocol (Version III) TEST CONDITIONS Impact Speed and Overlap

Offset barrier crash tests are conducted at 40 mi/h (64.4 km/h) and 40 percent overlap. The test vehicle is aligned with the deformable barrier such that the right edge of the barrier face is offset to the left of the vehicle centerline by 10 percent of the vehicle’s width (Figure 1). The vehicle width is defined and measured as indicated in SAE J1100 – Motor Vehicle Dimensions, which states, “The maximum dimension measured between the widest part on the vehicle, excluding exterior mirrors, flexible mud flaps, and marker lamps, but including bumpers, moldings, sheet metal protrusions, or dual wheels, if standard equipment.
