1. A containment impact sled for use in an end treatment array for attenuating the forces generated by a vehicular impact, the containment impact sled comprising:

  • a frame extending in an axial direction and comprising;

    a first side frame member;

    a second side frame member spaced from the first side frame member; and

    an end frame member extending across a width of the frame and securing the first side frame member to the second side frame member, said frame members together defining an interior space;

    wherein each of said side frame members comprise a bottom frame member and a top frame member, wherein the bottom frame member is disposed substantially horizontally, and the top frame member extends downwardly at an angle from its frontmost end to its rearmost end, with the frontmost end of the top frame member being connected to said end frame member near a top of said end frame member and the rearmost end of the top frame member is connected to a rearmost end of the bottom frame member near ground level, such that each side frame member is triangular in shape;

    a floor attached to and extending between each of said side frame members and said end frame member; and

    an upright wall attached to a front end of said end frame member;

    wherein the containment impact sled is adapted for attachment to an adjacent barrier module in an assembled end treatment array in such a manner as to contain a substantial portion of said adjacent barrier module within said interior space when the end treatment array is assembled.
