An aerodynamic underride guard comprising an angled front section located ahead of the trailer landing gear, a crash attenuating middle section located between the trailer landing gear and the trailer wheel assembly, and an angled rear section located in proximity to the trailer wheel assembly. The front angled section deflects air away from the non-aerodynamic features of the trailer landing gear. The rear angled section deflects air away from the non-aerodynamic features of the trailer wheel assembly, and the crash attenuating middle section can prevent vehicles from under riding the trailer.

The invention claimed is: 1. An over-the-road trailer comprising: a frame adapted for carrying cargo; a wheel assembly and a landing gear assembly, each connecting to the frame; the landing gear assembly including a non-retractable portion capable of moving a plurality of vertically retractable landing gear legs; a fairing interconnected with and located below the frame, the fairing having a bottom surface extending from about the wheel assembly to about the landing gear assembly; the plurality of vertically retractable landing gear legs extending through a plurality of apertures in the bottom surface of the fairing; the shape of each aperture substantially defined by a single vertically retractable landing gear leg. 2. The over-the-road trailer of claim 1 further comprising the fairing including a first and second sidewall, the sidewalls separated by a distance substantially similar to the width of the frame; the bottom surface of the fairing connecting to and extending between the first and second sidewalls. 3. The over-the-road trailer of claim 2 further comprising the fairing having a front surface connecting to the bottom surface and both of the sidewalls; wherein substantially all of the non-retractable portion of the non-retractable portion of the landing gear assembly is located directly between the front surface and wheel assembly. 4. The over-the-road trailer of claim 3 wherein the front surface includes a substantially flat surface portion connected between a first and second concave surface portion. 5. The over-the-road trailer of claim 3 further comprising an impact-absorbing underride guard connected to the frame of the trailer, wherein substantially all of the underride guard is located directly between the bottom surface and the frame. 6. The over-the-road trailer of claim 5 further comprising the impact-absorbing underride guard having a network of energy absorbing structural supports secured to the frame; and the frame and the fairing cooperating to enclose both the impact-absorbing underride and the non-retractable portion of the landing gear assembly. 7. The over-the-road trailer of claim 6 the network of energy absorbing structural supports including a plurality of impact absorbing foam sections; and each of the plurality of vertically retractable landing gear legs having a portion that is always located below the bottom surface of the fairing. 8. The over-the-road trailer of claim 3 further comprising an impact absorbing foam lattice extending between and connecting to both the first and second sidewall. 9. The over-the-road trailer of claim 3 further comprising the non-retractable portion of the landing gear assembly including a first and second fore stabilizer rod, each stabilizer rod extending towards the frame at a first angle; and the front surface of the fairing extending from the bottom surface towards the frame at substantially the first angle. 10. The over-the-road trailer of claim 8 further comprising the first and second sidewalls including a plurality of openings; the foam lattice having a plurality of voids aligned with the plurality of openings; wherein at least one of the voids is larger than a spare tire for the wheel assembly. 11. The over-the-road trailer of claim 3 further comprising the non-retractable portion of the landing gear assembly having a crank for vertically moving the vertically retractable landing gear legs; the first sidewall having an opening proximal to the crank; and a door connected to the first sidewall near the opening, the door capable of securing the first opening. 12. The over-the-road trailer of claim 1 further comprising: a kingpin, each connecting to the frame; the landing gear assembly located between the kingpin and the wheel assembly; the landing gear assembly including a first fore stabilizer distant from a second fore stabilizer, each fore stabilizer connecting to one of a plurality of receivers adapted for vertically moving one of the vertically retractable landing gear legs, and each fore stabilizer substantially located between one of the plurality of receivers and the kingpin; and the fairing including a front structure extending between and connecting to both the first fore stabilizer and the second fore stabilizer, the fairing having a first and second sidewall, each sidewall connecting to the front structure and extending to about the wheel assembly. 13. The over-the-road trailer of 12 wherein the first sidewall has a cross-section with a first convex section, a second convex section, and a first concave section; the first concave section connecting between the first and second convex sections. 14. The over-the-road trailer of claim 13 further comprising the second concave section of the first sidewall substantially surrounding a horizontal impact member. 15. The over-the-road trailer of claim 12 further comprising an impact absorbing foam lattice extending between and connecting to both the first and second sidewall; the foam lattice including a resilient section with a high density foam and a compression section with a low density foam. 16. The over-the-road trailer of claim 15 further comprising the first and second sidewalls including a plurality of openings; the foam lattice having a plurality of voids aligned with the plurality of openings; wherein at least one on void is larger than a spare tire for the wheel assembly.
