Description / Abstract:
The procedure applies to heavy vehicles weighing more than
11800kg (26 000lb) and particularly to those vehicles having two or
more articulation joints that allow rotation in a horizontal plane.
The procedure pertains to the lateral directional response of
multi-articulated vehicles in avoidance maneuvers performed at
highway speeds without braking.
Purpose- This test procedure is intended to be
used for determining the rearward amplification and dynamic off
tracking qualities of multi-trailer commercial vehicles (heavy
trucks and buses).
