RED CEDAR WOOD POST SINGLE SIGN SUPPORT SYSTEM LOW-SPEED TEST, FOIL TEST NUMBER 93F001

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 32 km/h (20 mi/h), test 93F001. The vehicle used for this test was the FOIL's reusable breakaway bogie. The purpose of this test was to evaluate the low-speed safety performance of the South Dakota red cedar post sign support. The sign support was made from a 102-mm by 152-mm (4-in. by 6-in.) western red cedar wood post. No holes were drilled in the post, and the post was buried 1.2 m (4 ft) in weak soil. 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 4.9 m/s (16 ft/s) or less, that the significant test article stub height remaining after impact be no more than 102 mm (4 in.), and that there be no occupant compartment intrusion. The test results indicate that the western red cedar wood post sign support system meets all of the applicable safety criteria for the low-speed test in weak soil as specified by the FHWA.
