A reinforced traction aid device is provided for use with heavy transport and utility vehicles (HTUVs). The device comprises a U-shaped frame and a plurality of cross bars joining the side bars of the frame. This configuration provides structural support and traction means for a tire of a HTUV to engage and climb over the device when in use. Traction cleats engage the ground surface and stabilize the traction aid device, and two converging claws supported by a claw brace form the open end of the U-shaped frame to engage the tire tread cavities of the tire. A brace system is integrated into the device, comprising at least one linear and one or more additional linear and/or V-braces disposed in between the end bar of the U-shaped frame and cross bars to reinforce and help maintain the structural alignment of the traction aid device after repeated use.
