A support arrangement for supporting an object above ground level is designed to reduce hazards for passing motorists. The support arrangement includes an above-ground portion rigidly connected to an in-ground portion by a frangible connector assembly. The above-ground portion can include a generally horizontally extending portion for supporting an object in a cantilevered manner. The horizontally extending portion is formed as part of a moveable portion connected to a generally vertically extending fixed portion by a rotatable connector assembly. The support arrangement is designed to bend and break away in a predetermined manner when impacted and, if it does not break, the rotatable connector is designed to permit the moveable portion to be pulled free and thrown clear of the vehicle. If only the cantilevered object is impacted, the object and moveable portion can rotate out of the path of the impacting force. Once the impacting force has passed, the moveable portion will return to an at-rest position.
