A sign mounting adapter system includes a hitch extension tube. A sign orientation post connected and oriented perpendicular to the hitch extension tube has a longitudinal axis. A sign support post is axially and rotatably received on the sign orientation post. The sign support post has a longitudinal axis co-axially aligned with the sign orientation post longitudinal axis, and a receiving bore perpendicular to the sign support post longitudinal axis. Multiple orientation bores extend through the sign orientation post, each oriented at a first angle to proximate orientation bores and perpendicular to the orientation post longitudinal axis. A retention assembly is releasably and co-axially received in the receiving bore and one of the orientation bores. The retention assembly releasably connects the sign support post to the sign orientation post to permit selection of a sign support post axial angle of rotation to the sign orientation post.
