This report presents the results of the six passenger car-to-rear underride crash tests conducted in accordance with the requirements of Task 4 of the "Development of Compliance Test for Truck Rear Underride Protection" program. The test vehicles selected for Task 4 tests were 1978 VW Rabbit and 1978 Chevrolet Impala four-door sedans. These vehicles were impacted into a bolt-on underride guard (Fruehauf Part No. FCE-1456-1) mounted to a truck-trailer body simulator. The trailer body simulator used for the tests was modified 1977 Fruehauf 40-foot heavy duty platform trailer with Select-A-Point tandem rear wheels. For these six tests, two instrumented 50th percentile Part 572 anthropomorphic dummies were placed in the driver and front passenger positions in the car. The occupants were restrained with the vehicle's restraint system. The seat tracks were welded in the mid-position to prevent breakaway and/or rotation.
