Does the trailers rotation push an impacting vehicle into traffic?
When the TTMA-100 captures the front of an impacting vehicle, it actually begins to pull the vehicle into the cushion. Further, by aligning itself with the impact, the TTMA-100 is able to maximize energy dissipation and avoid pushing the vehicle into adjacent traffic lanes. Comparison of vehicle rest locations after the pickup truck offset and angled tests (tests 3-52 and 3-53, respectively) with other TMA systems shows that the TTMA-100 has no greater tendency to push vehicles into adjacent traffic lanes than other trailer TMA designs. Further, the TTMA-100 was tested with a blocked support truck while all other systems were tested with relatively light, 20,000-lb support vehicles. A light support truck rolls ahead as much as 16 ft during an impact to significantly increase the effectiveness of an attenuation system. Hence, the TTMA-100 performed just as well as the other TMA and trailer systems, even though it was tested under much more stringent conditions. Therefore, it must be con
