ABSTRACT:
A trailer hitch guide includes a plurality of visual guides that are stored in an out-of-the way location and are deployed automatically as the element being carried on the trailer moves off of that trailer. The visual guides are located to provide an exact positional readout to the vehicle driver, and a template can be mounted within the vehicle to quantify the amount of misalignment between the vehicle and the trailer. Mispositioning of the vehicle in a single plane can be indicated and mispositioning of the vehicle plane with respect to the trailer plane can also be indicated.
