A tractor-trailer coupling mechanism for a powered tow vehicle and unpowered trailer vehicle which eliminates jack-knifing. The coupling includes at least one extension or more on the trailer vehicle which is constructed to slide into a receptor channel or recesses in the powered vehicle. A locking or latching arrangement is attached at the front of the tractor vehicle. The result is that the tractor vehicle and the trailer vehicle are fixedly connected to each other as a single chassis vehicle, making the powered tractor vehicle and the trailer vehicle operate as one unit. An alternative arrangement would provide the channel on the trailer and the extension protruding from the powered tractor vehicle.

What is claimed is: 1. A tractor-trailer combination comprising a tractor vehicle and a trailer vehicle, wherein: a) the trailer vehicle, having a length and a front end, comprises a plurality of reinforcement rods extending along the length of the trailer vehicle and protruding from the front end

What is claimed is: 1. A tractor-trailer combination comprising a tractor vehicle and a trailer vehicle, wherein: a) the trailer vehicle, having a length and a front end, comprises a plurality of reinforcement rods extending along the length of the trailer vehicle and protruding from the front end of the trailer vehicle as extensions of said reinforcement rods; b) the tractor vehicle, having a length, a rear end, and a front end, comprises the same plurality of receptor channels as the plurality of reinforcement rods; c) the receptor channels are positioned such that the extensions are able to slide into the corresponding receptor channels so as to join the tractor and trailer vehicles, thereby enabling the tractor-trailer combination to act as a single unitary vehicle; d) the receptor channels extend from the rear end of the tractor vehicle to the front end of the tractor vehicle; e) the extensions have a length greater than the length of the tractor vehicle, such that when the tractor and trailer vehicles are joined, the extensions protrude from the front end of the tractor vehicle through the receptor channels; and, f) the extensions and receptor channels comprise matching apertures or locking mechanisms that permit the extensions to be securely attached to the receptor channels. 2. The tractor-trailer combination of claim 1 wherein the number of the plurality is two. 3. The tractor-trailer combination of claim 1 wherein the apertures or mechanisms of the extensions and receptor channels permit the extensions to be securely attached to the receptor channels at the front end of the tractor vehicle. 4. The tractor-trailer combination of claim 1 wherein the tractor vehicle further comprises four powered wheels. 5. The tractor-trailer combination of claim 4 further comprising four-wheel synchronized steering. 6. The tractor-trailer combination of claim 1 wherein the extensions can retract into the reinforcement rods so as not to protrude from the front of the trailer vehicle when such protrusion is not desired. 7. The tractor-trailer combination of claim 1 wherein the reinforcement rods can be removably mounted to the trailer vehicle.
