The present invention provides a trailer to transport materials or equipment, the front tongue assembly of which converts to a highway traffic arrow board, or other preferred display, and which locks the trailer securely in place. The tongue extension frame extends through and pivots on the trailer frame and is moved to vertical by rack and pinion, or other suitable means such as hydraulic cylinder. Its upper end pivotably supports a Y-shaped tongue assembly with sign affixed opposite the towbar and hitch means. Power is applied to a gear box mounted on upper end of said tongue extension frame which turns the pivot bar 180 degrees to place the sign at the top for display and the towbar with hitch means at the bottom. Flip-down legs with extended side supports give added stability in the setup positions.
