Abstract: Apparatus for guiding the driver of a towing vehicle in positioning a first hitch element on the towing vehicle adjacent a complementary second hitch element on a trailer so that they can be readily engaged. The apparatus includes an arm which is adapted to be releasably mounted to the second hitch element. The arm has a first portion extending transversely from the second hitch element to beyond the side of the towing vehicle, and a second portion extending forwardly closely adjacent the side of the towing vehicle to indicate to the driver when the towing vehicle and trailer are transversely aligned. The guide apparatus further includes sensing means which are mounted proximate the second hitch element and are adapted to be actuated by the first hitch element as the towing vehicle and trailer are moved into positions in alignment with one another so that their hitch elements are adjacent.
