A multi-section support post for a reflective, roadway delineator that collapses upon impact at a replaceable joint. A ground stake and a sign stake are joined together with hardwood blocks that are separated with a material having a large coefficient of friction. The blocks are secured with a pivot bolt to recessed channels at the stakes. An intervening layer of tarpaper is compressed between the blocks. The sign stake collapses at the joint upon impact, such as from a snowplow. A reflective roadway delineator rotates about a pivot bolt or axle that projects from the sign stake.
