The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. A visual warning device adapted to extend between a first cargo-carrying unit and a second cargo-carrying unit that is towed following the first cargo-carrying unit by a connecting drawbar, the visual warning device comprising: (a) a first mounting fixedly attached to the first cargo-carrying unit at a higher elevation than the connecting drawbar; (b) a second mounting fixedly attached to the second cargo-carrying unit at a higher elevation than the connecting drawbar; and (c) a first conspicuous, elongate belt having a first end that engages the first mounting and a second end that engages the second mounting; wherein the first and second mountings are disposed between 48 inches and 80 inches above ground level. 2. The visual warning device of claim 1, wherein the first mounting comprises a first plate portion fixedly attached to the first cargo-carrying unit and a second plate portion pivotably attached to the first plate portion, and further wherein the first end of the elongate belt releasably engages the second plate portion. 3. The visual warning device of claim 2, wherein the second plate portion further comprises an aperture and the first end of the elongate belt further comprises a rigid hook that engages the second plate portion through the aperture. 4. The visual warning device of claim 1, wherein one of the first and second mountings adjustably engages the elongate belt such that the effective length of the elongate belt is adjustable. 5. The visual warning device of claim 1, wherein the elongate belt further comprises a locking device for fastening the elongate belt at a predetermined effective length. 6. The visual warning device of claim 1, wherein at least one of the first or second mountings comprises a take-up reel for the elongate belt. 7. The visual warning device of claim 1 further comprising a second conspicuous, elongate belt, wherein the first elongate belt is attached on a right side of the first and second cargo-carrying units and the second elongate belt is attached on a left side of the first and second cargo-carrying units. 8. The visual warning device of claim 7 further comprising an equalizer strap, wherein a first end of the equalizer strap is attached to the first elongate belt and a second end of the equalizer strap is attached to the second elongate belt. 9. The visual warning device of claim 1, wherein the elongate belt comprises an elastic material. 10. The visual warning device of claim 1, wherein the elongate belt comprises a reflective material. 11. The visual warning device of claim 1, wherein the elongate belt comprises a brightly-colored material. 12. The visual warning device of claim 1, wherein a surface of the elongate belt is illuminated. 13. The visual warning device of claim 1, wherein the elongate belt comprises an abrasive outer surface such that the belt produces an audible sound when contacted at freeway speeds. 14. A warning device for use with a transfer dump system comprising a dump truck and a pull trailer that is towed following the dump truck by the connecting drawbar, the warning device comprising: (a) a first bracket fixedly connected to the dump truck at a higher elevation than the connecting drawbar; (b) a second bracket fixedly connected to the pull trailer at a higher elevation than the connecting drawbar; and (c) a conspicuous, tensioned strap extending between the dump truck and the pull trailer, wherein the tensioned strap has a first end that is connected to the first bracket and a second end that is connected to the second bracket wherein the first and second brackets are disposed between 48 inches and 80 inches above ground level. 15. The warning device of claim 14, wherein the tensioned strap is releasably connected to one of the first and second brackets. 16. The warning device of claim 14, wherein the effective length of the tensioned strap is adjustable. 17. The warning device of claim 14, wherein the tensioned strap comprises an elastic, brightly colored material. 18. The warning device of claim 14, wherein the tensioned strap comprises a reflective material. 19. A method of providing a visual indicator of a region between a dump truck and a pull trailer that is towed following the dump truck by a connecting drawbar, the method comprising: (a) providing a first bracket fixedly connected to the dump truck at a higher elevation than the connecting drawbar; (b) providing a second bracket fixedly connected to the pull trailer at a higher elevation than the connecting drawbar; (c) attaching a conspicuous, adjustable belt extending between the dump truck and the pull trailer, wherein the adjustable belt has a first end that is connected to the first bracket and a second end that is connected to the second bracket; and (d) adjusting the length of the adjustable belt such that the effective length of the adjustable belt is comparable to an interval between the dump truck and the pull trailer; wherein the first and second brackets are disposed between 48 inches and 80 inches above ground level. 20. The method of claim 19, wherein the adjustable belt is releasably connected to one of the first and second brackets. 21. The method of claim 19, further comprising a locking device that can be used to attach a length of the belt to itself. 22. The method of claim 19, wherein the adjustable belt is reflective. 23. The method of claim 19, wherein the adjustable belt is attached to a right side of the dump truck and the pull trailer and to a left side of the dump truck and the pull trailer.
