Abstract:This test report contains the results of a crash test performed at the Federal Outdoor Impact Laboratory (FOIL) in McLean, Virginia. The test was performed on a small sign support system at 60 mi/h (96.6 km/h), test 92F040. The vehicle used for this test was a 1986 Honda Civic. The purpose of this test was to evaluate the high-speed safety performance of a triple-legged 12-gauge 1.75-in (44.4-mm) square tube sign support. The performance evaluation was based on the latest requirements for breakaway supports as specified in Volume 54, Number 3 of the Federal Register dated January 5, 1989. These criteria specify, in part, that the occupant change in velocity must be 16 ft/s (4.9 m/s) or less, that the significant test article stub height remaining after impact be no more than 4 in (101.6 mm), and that there can be no occupant compartment intrusion. The test results indicate that the square tube sign support system does not meet all of the applicable safety criteria for the high-speed test in strong soil as specified by the FHWA.
