1. The TMA should be rigidly fastened to the truck. In the
horizontal position, the bottom of the TMA should be
280 to 330 mm [11" to 13"] from the ground and level
(see Figure 3). *The TMA should be left in the folded
position whenever it is not being used as an impact
attenuator. The TMA can only absorb the energy of an
impacting vehicle in the unfolded position.
2. Jacks may be used to support the folded TMA when
it is off the truck. The jacks must be stored while the
TMA is attached to the truck. The jacks can be stored
on the brackets provided on the support frame. (See
Figure 3). If you are subject to vandalism, prepare
another storage plan.

*The Safe-Stop 180 TMA shall be employed in the un-
folded position: At
all times while operating as either a
Barrier Vehicle or Shadow Vehicle.
The Safe-Stop 180 TMA should be in the "unfolded" po-
sition when: Transporting short distances at a low speed,
Transporting at a speed much lower that adjacent traffic,
and Transporting in areas where vehicle ride characteris-
tics and maneuverability are maintainable.
The Safe-Stop 180 TMA should be in the "folded" posi-
tion when: Transporting long distances at a high speed,
Transporting at a speed near the speed of adjacent traf-
fic, and Transporting under conditions of compromised
maneuverability typically when the large turning radius
clearance needed for the extended TMA is not safe.
