Methods and apparatus are provided for determining the intent of a driver of a motor vehicle in moving a trailer towed by the motor vehicle along a desired path. The method comprises the step of positioning a first reference point at a first location spaced apart from the motor vehicle and sequentially positioning a second reference point at a plurality of way points along the desired point. A signal relative to the motor vehicle, the first reference point, and the plurality of way points is transmitted as the second reference point is positioned at each of the way points. The transmitted signals corresponding to each of the way points are received and are used to determine the position of the plurality of way points relative to the motor vehicle by a process of triangulation. The position of the plurality of way points indicate positions along the desired path.
