This report contains the test procedures, test setup, and test results from two crash tests performed at the Federal Outdoor Impact Laboratory (FOIL) located at the Turner-Fairbank Highway Research Center in McLean, Virginia. The objectives of these tests were to evaluate the safety performance of a large sign support system provided by the Oregon Department of Transportation (DOT) and to provide Federal Highway Administration (FHWA) finite element model simulation engineers with data on the performance of a slip-base sign support. Previous testing on Oregon slip-base sign supports was conducted a the FOIL. These tests demonstrated a problem with the slip-base sign supports was conducted at the FOIL. These tests demonstrated a problem with the bolt-notch angle from 60 deg. to 90 deg. This change was made to one slip-base sign support design and to the new system tested at the FOIL. This report documents the results from two crash tests using the FOIL bogie vehicle and the Oregons DOT's 8 by 8 TBB sign support. The two tests were conducted at nominal test speeds of 35 km/h and 100 km/h. The results indicate that the larger notch angle improves the safety performance of the sign support. The sign support met the FHWA safety performance criteria outlined in National Cooperative Highway Research Program (NCHRP) Report Number 350.
