    Abstract: A vehicle-positioning aid includes a field unit and a cab unit. The field unit is configured to generate a vehicle-contact signal when physically contacted by a vehicle and to wirelessly transmit a signal indicative that the field unit has be contacted by a vehicle. The cab unit is configured to provide the vehicle operator with an indication that the vehicle has contacted the field unit; for example, by emitting a particular sound pattern. The operator places the vehicle-positioning aid at a desired location on, for example, a worksite, and is able to position the vehicle at the desired location by moving the vehicle until it contacts the field unit. Thus, the operator is able to position the vehicle at a desired spot without the need for other workers (spotters) to monitor the blind spots and relay information to the operator.
