A lift truck has a pair of wheel assemblies each of which is rotatable about a pivot point relative to the chassis of the truck through at least 90 degrees between a forward mode and a sideward mode. The wheel of each assembly is laterally offset from the assembly's pivot point, causing the wheel to describe an arcuate path over the ground as it transitions between the forward and sideward modes. During the transition, an actuator acts on each wheel assembly to pivot the assembly about the pivot point, while drive is applied to the wheel to positively drive the wheel along the arcuate patch at a speed that matches the pivotal rotation caused by the actuator. This positive drive imparted to the wheels during the transition prevents the truck from rolling if it is located on a slope during the change in orientation of the wheel assemblies.
