Yes, an optional arrow board support mount is available for use with the TTMA-100 to accommodate an arrow board or a variable message sign. The arrow board support mount is specifically designed to handle the maximum impact loads experienced by the TTMA-100 and the support truck during crash tests under NCHRP 350 test conditions. During an impact, the TTMA and the support truck are accelerated forward. The concern is that the support mount would collapse and allow the arrow board to crash into the windshield of the impacting vehicle. By designing for the maximum impact force experienced during a crash, the support mount will remain attached to the Trailer TMA and will not collapse, thus eliminating the concern that the arrow board or variable message sign would fall and contact the impact vehicle.
