1. A method of controlling a bed of an articulated dump truck, comprising:
sensing a speed of the dump truck;
sensing a position of the dump truck bed;
sensing actuation of a manual override switch by a user;
comparing the sensed speed of the dump truck to a predetermined speed; and
if the dump truck bed is at least partially raised, automatically lowering the dump truck bed in response to and the sensed speed of the dump truck equaling or exceeding the predetermined speed and the manual override switch not being actuated; and
if the dump truck bed is at least partially raised, refraining from automatically lowering the dump truck bed in response to the sensed speed of the dump truck equaling or exceeding the predetermined speed and the manual override switch being actuated.
