A rough terrain vehicle is described which includes auxiliary wheels that can be deployed to avoid overturning the vehicle when turning while traversing a slope, to climb an embankment or the like, and to right the vehicle when it is overturned. The vehicle includes a pair of front and rear primary wheels, and a pair of auxiliary arms having inner ends pivotally mounted on the front wheel axes and outer ends that carry auxiliary wheels. A motor can turn the arms to move the auxiliary wheels from a stowed position about halfway between the front and rear wheels and above the ground, to a second position against the ground to stabilize the vehicle. The arms can be turned more than 180.degree. to move the auxiliary wheels in front of the front primary wheels to help climb an embankment. The primary wheels can be mounted at the end of primary arms, so when the primary arms are turned they not only move the primary front wheels but also the inner ends of the auxiliary arms.
In a rough terrain vehicle which includes a chassis having front and rear portions and laterally spaced opposite sides, a pair of front primary wheels on either side of the chassis, and a pair of rear primary wheels on either side of the chassis, the primary wheels being rotatably mounted on the chassis about parallel lateral axes, the improvement including:
