PRODUCT DESCRIPTION

New Hardware or 

Significant Modification

Modification to 

Existing Hardware

Each test was performed using a proprietary Truck Trailer Mounted Attenuator (“TTMA”), manufactured by 

Verdegro® Holding BV, and attached per the manufacturers instructions to a 1999 Ford F-750 single-unit 

support truck.

The TTMA is attached to the rear end of the support truck via a special hitch system, which attaches then to the 

main body of the TTMA. The TTMA has a sleeve on each side, which has metal slides that can slide into the 

sleeves to collapse the TTMA down for transport. The rear end of the TTMA connects the two slides together 

with a panel system. The trailer has two wheels, and also a sign board which extends above the trailer there the 

receiving hitch meets the body of the trailer. The TTMA measured 6.2 m (247 inches) long from the pintle hitch 

to the back of the TMA in the deployed position. The TTMA itself measured 5 m (197 inches) in length and its 

hitch attachment assembly measured 1.2 m (50 inches) in length. The TTMA with both mast and arrow board 

weighed 1243 kg (2740 lb).
