The report describes a series of full-scale vehicular crash tests conducted to evaluate the impact performance of small sign supports used by the Arizona Department of Transportation. The tests were conducted and evaluated in accordance with the recommendations of NCHRP Report 230 and the 1985 AASHTO 'Standard specifications for structural supports for highway signs, luminaires and traffic signals.' Based on the test program, it was concluded that the following systems are in compliance with recommended safety performance standards: one P1 post; one 3 lb/ft U-post; one 4 lb/ft U-post; two 3 lb/ft U-posts; and a slipbase design having two S4 x 7.7 posts with a hinge at the midheight of the sign panel. It was concluded that the following systems are not in compliance with recommended safety performance standards: two or more P2 posts within a 7 ft spacing; three or more 3 lb/ft U-posts within a 7 ft spacing; and two or more 4 lb/ft U-posts within a 7 ft spacing.
