ABSTRACT:
An alignment assembly includes first and second markers that have shafts provided with opposed ends. Each shaft has a bottom end situated below an operator's line of sight and top end situated within the operator's line of sight such that the operator can identify a location of the markers. The first marker is seated on the rear of the vehicle hitch. The second marker is seated on a proximal end of the trailer hitch. Each marker has a diameter less than a width of the vehicle and trailer hitches so that the markers maintain continuous surface area contact therewith. A mechanism is included for locking the second marker at a static position. The locking mechanism is spaced from the first marker and independently operable therefrom. The vehicle operator can determine when the vehicle and trailer hitches are aligned by aligning the first and second markers in a linear relationship.
