• Abstract:
  This report describes a vehicle crash test on a mile post marker. The vehicle was a sedan weighing 3400 lbs. and was towed into the mile post marker at 43.9 mph. The mile post marker, proposed for use on interstate highways, consisted of a 1 ft. by 4 ft. sign panel mounted on a 2 in. standard pipe 8 ft. high with a threaded coupling as a breakaway feature. The standard threaded coupling breakaway feature resulted in only 1.6 mph change in vehicle velocity during impact. However, the behavior of the sign panel and post, which struck the windshield, is considered undesirable. Penetration through the windshield was estimated to have been about 3 in. and was reduced by the sign's contact with the vehicle's cowling, windshield, wiper assembly and top of dash.
